Tuning VAZ 2104: modifications to the exterior and interior, modernization of the technical part

Internal changes

The inside of the car will require just as much work as the outside. By internal tuning we mean pumping the engine, replacing the brake system and modifying the interior. But first things first.

Engine and brakes

Tuning of domestic cars is embodied not only in external changes, but also in internal ones. Believe me, there are many parts under the hood that need reorganization or complete replacement. The main element of any car - the engine - is primarily subject to tuning. If your car has its original power unit, which has faithfully served its intended life, then it is better to send it to a well-deserved rest, that is, to scrap metal. Still, the metal is quite tired, and there is also physical wear and tear - these factors do not allow us to talk about further refinement and boosting. There is only one conclusion - the old engine, which has unscrewed several circles of the speedometer, must be replaced, and newer units can still be worked on.

A worthy replacement for the old engine will be a powerful unit taken from the VAZ-21213, its volume will be 1900 cm3. Its power can be increased from 79 to 120 horses, but this will require some effort and parting with your hard-earned money. The forcing process consists of boring the channels, grinding the intake manifold, and installing cast pistons with a diameter of 82 mm. To change the valve timing, you will need to purchase a new camshaft, with which it will be possible to lift the valves up to 10.8 mm.

By using a sports crankshaft of 88 mm and increasing the level of piston lift, you can increase the volume of the power unit and make it easier to remove the increased force that occurs during the combustion of the fuel-air mixture.

Installing a lightweight flywheel will reduce the loss of power that is spent on spinning up the engine. As a result, the car will gain the required speed in a short time.

The exhaust and power system also need modernization, which consists of installing an air filter, a sports exhaust manifold and a direct-flow muffler.

The engine of any old car needs to be modernized

It remains to modernize the brakes, which are responsible for the safety of the driver, his passengers and other road users. The drum brakes, which are available on the rear axle in the VAZ-2104, are difficult to operate and are also not effective enough. Their replacement is required; 13-inch ventilated disc brakes are well suited for this.

Change of interior

The effect of all external changes that occurred with the VAZ-2104 will be irrevocably spoiled by the outdated interior. Internal tuning is no less important than upgrading the engine and working on the body. Everything can be very simple here. If the seats are in good condition but look shabby, you can replace the upholstery. If you have enough funding, you can choose leather material for upholstery, but any other will also look good. Carbon fiber decor is a great way to enhance the effect of tuning and make the interior more expensive.

Any car can be restored, transformed and improved upon its previous characteristics. This is especially true for domestic models, for example, the VAZ-2104; do-it-yourself tuning, although it requires an investment of money and finances, is worth it.

Introduction

Tuning the interior of a VAZ-2104 is a labor-intensive, but very effective modernization of a domestic vehicle, which is in many ways inferior in its characteristics and interior to similar foreign versions.
In fact, for a person who is just thinking about ways to improve the properties and abilities of the VAZ-2104, there are many different ways that, as a result, will radically transform the boring car. It is worth noting that due to the relative low cost of components for the VAZ-2104, which has long been removed from the manufacturer’s tape, the motorist has the opportunity to tune almost all parts of the device for modest funds. In particular, a powerful power unit and a more refined body can be installed on a VAZ-2104 car. In addition, interior tuning can be an important modification of movable property. Let's consider methods and methods for refining the internal space of the domestic “four”

The VAZ 2104 interior is not distinguished by any special aesthetics, so many motorists want to improve their interior

Time has passed and after long nights in the garage under the car and on it, in front of you is a completely new, luxurious car with a strong engine and a fantastically attractive exterior. Now the stars have aligned in the right direction and the time has come to upgrade the interior

He has been waiting for a very long time for people to pay attention to him and he really needs it, because he is old and ugly

There are many options for changes here. First, change the lighting of the VAZ 2104 instruments. The inside of the car will become more joyful and optimistic. And driving the car will become much more comfortable.

What you need to replace the backlight:

• LED bulbs;
• screwdrivers of different sizes;
• strong glue;
• modern, fashionable scales for the speedometer and other instruments;

First of all, we remove the instrument panel of the “four”. We uncork the special latches on all sides of the shield and unscrew the bolts with screwdrivers. Separate the scales and turn off the backlighting devices. We place diode lamps in the vacant spaces and insert translucent scales above them. You can spread glue on the edges of the scales. We check the operation of the devices and install the panel back.

A lowered interior and reduced ground clearance are also ways to achieve a new ideal look for your “fourth” baby.

A useful technical insert that eliminates body sway and softens the ride is air springs, they are mounted inside the springs. Air springs work both on a lifted body and when the car is factory assembled.

Nothing pleases the eye like a good car paint job. Correctly selected color scheme and competent application of paint is already half the success. Spit in the eyes of anyone who says that airbrushing is only for expensive cars produced exclusively in the West. To upgrade the VAZ 2104, it is necessary like air. A wide space on the body attracts the hand of a talented artist, with a spray bottle in his hand.

Arography is not a scribble, but a true art. Remove everything unnecessary from the car that could spoil a beautifully painted picture, in short, remove the trunk from the roof. Dismantle the factory engine, which still remembers the heyday of Soviet power, and take it to the farthest scrap metal collection point. Anyone who has studied strength of strength knows that metal fatigue has not been canceled. When the engine is on its last legs, the chances of making it more powerful, stronger and more modern are zero. The possibility of forcing is completely excluded.

An engine from the distant past will replace a cooler, modernized engine from a VAZ 21213 with a volume of 1900 cm3. If you want more, well, then pay! Bore the duct head, grind the intake manifold and install 82mm cast pistons and a new camshaft. An 88 mm crankshaft with high piston lift will make the engine displacement larger and make it easier to remove the increased force of the burning mixture.

A new modern flywheel will reduce power loss during engine spin-up and make it possible to quickly pick up speed.

VAZ-2104 engine and its features

Do-it-yourself tuning of the VAZ 2106 interior

Engine 2104-1000260

can be used for installation on VAZ 2103, 2104, 2106, 21053, 2107 cars. Initially, the VAZ 2104 engine was produced only in a carburetor version. Subsequently, it was modified to use a fuel injection system and received the designation VAZ 2104-21. The VAZ 2104 engine was created on the basis of the previous model - VAZ 2103. The design used: a cylinder block, a connecting rod and piston group, a timing drive and a crankshaft from the 2103 engine.

photo VAZ-2104 engine

Cylinder block from a VAZ 2103 engine. Cylinder diameter - 76.00 mm. The accepted overhaul dimensions are 76.40 and 76.80. The engine is equipped with a crankshaft 2103 or an interchangeable shaft model 21213. To ensure the operation of the injection system, it was necessary to install components and parts from other engines that were originally developed for an injection fuel supply system. A new camshaft drive cover is used, on which there is space for installing a sensor that controls the position of the crankshaft. It was necessary to install cylinder head 2104-1003015, an original design, with enlarged areas for the intake manifold. The design of the head provides for the installation of nozzles. The camshaft, valves and springs correspond to those installed on the VAZ 2103 engine. The installation of hydraulic supports for the valve levers is not provided. The timing drive is carried out from a double-row bush-roller chain 2103-1006040. The chain tensioning mechanism is mechanical, similar to the device on the VAZ 2103 engine.

A pulley with a damper and a drive disk 21214-1005058-11 is installed on the crankshaft. To drive the generator, a belt 2107-1308020 is used (length - 944 mm). The injection modification 2104 has an original power system. The system includes an electric fuel pump with a fuel level indicator sensor, fuel lines, a fuel filter, a fuel rail with injectors, an air filter, air supply hoses, a throttle valve and a fuel vapor recovery system. To clean the air entering the engine, an air filter model 2112 is installed. A receiver model 2104 or model 2123-1008027 is installed together with the intake manifold. To adjust the volume of incoming air, a throttle pipe 2112 is installed. The electric fuel pump module 21073-1139009 is installed in the tank and supplies fuel to the fuel rail and injectors. The original fuel rail 2104-1144010 is used, box type with pressure regulator and return drain pipe. Injection is carried out using four nozzles of pair-parallel action. It is possible to install nozzles BOSCH 0 280 158 502 (black, thin), SIEMENS VAZ 6393 (beige, thick) or other types with the appropriate parameters. The ignition system includes: a Model 2112 ignition module mounted on a special bracket on the cylinder block, spark plugs and high voltage wires. The ignition module includes two ignition coils and two electronic control devices. In accordance with control signals from the control unit, the ignition module generates and supplies high-voltage pulses to the spark plugs. Ignition control is assigned to the electronic engine management system. This system controls the amount of air and fuel supplied to the cylinders, controls the operation of the fuel pump, controls the supply of high-voltage pulses from the ignition coil to the spark plugs and adjusts the ignition timing, regulates the crankshaft speed at idle. The main control element of the system is the electronic control unit (ECU)-controller. The engine complies with EURO-2 toxicity standards.

The VAZ 2104 model was produced until 2012, and in recent years the car was produced in Izhevsk. She received many modifications. Cars of recent years of production were equipped with a radiator grille from the VAZ 2107.

Body tuning

Do-it-yourself VAZ 2112 tuning with photo

As a rule, first of all, drivers are engaged in upgrading the body, and such work can be both superficial and major.

Firstly, you can change the glass a little, for which you just need to purchase a tint film and paste it over the car windows, and in no case should you forget about the existing tinting standards. Fortunately, the modern market is able to offer car enthusiasts many different shades of tint film, so you can always choose the most suitable film. It is quite possible to glue the film yourself, especially since you can now find many manuals on this type of work on the Internet.

Secondly, the modern market offers car owners a variety of special body linings, with the help of which any car enthusiast can modify the body shape of a VAZ 2104

Before starting such a repair of a VAZ 2104, it is extremely important to obtain at least basic skills in working with the body, since otherwise, during the first trip after modernization, the car may simply fall apart. There are metal, plastic, fiberglass linings, and there are also carbon fiber body parts on the market

As a rule, the quality and price of body elements depends on the type of material.

Any car is given a special uniqueness by a design specially created for it, that is, airbrushing, but this service is known to be quite expensive. However, if you have the ability to draw, you can handle this yourself - you just need to take the work seriously.

What to consider?

Tuning ZAZ 965: global upgrade with your own hands

The film must be attached directly to the inside, because this way you can ensure its maximum protection from various damages.

If you need to tint the rear window of a car with your own hands, or you even want to tint all permissible windows, then you should first understand where this film can be installed and where it cannot. In Russia, in accordance with current legislation, tinting of front car windows can be carried out exclusively using a film in which the light transmittance is at least 75%.

What is the opinion of the owners

Lada 2104 attracts with its high utilitarianism, which ensures good demand for it. Owners value high practicality and high-torque engines, but reliability raises questions among many. Reviews say that the main weakness of the model is its poor corrosion resistance.

Tuning the “Four” is widespread. The changes concern the styling of the station wagon, as well as improving interior amenities.

In order to increase the traction performance of engines, owners bore the cylinders and install a more efficient carburetor. More detailed information about the modifications to the machine is contained in the videos, which can be found on the Internet.

Body transformation

In the process of tuning the famous “four” from VAZ, the greatest attention is paid to changing the body. Its design has long been no longer considered attractive and modern; now this angular shape looks outdated and unattractive

You can tune the body in several options, which differ in cost and amount of work:

1. easy consists of replacing the radiator grille, tinting the windows, installing rims on the wheels and a Vikhur skirt;
2. with average body tuning, it will be necessary to install alternative optics, replace the body kit, think about the likelihood of ordering professional airbrushing and shaving, which involves removing handles, locks and moldings;
3. deep, as you might guess, is the most complex, expensive and time-consuming, since it requires changes in the body structure, for example, changing the roof level, converting to a coupe, installing lambo doors.

Even a light tuning option will transform the appearance of the car. Sparkling chrome on the body, solid tinted windows, rare or, conversely, ultra-modern wheel covers - and your car will already look decent on the road.

Transformation of the appearance of the VAZ-21043

Changing the body structure

And if you take a more serious approach to transforming a domestic car and decide to “truncate” the body, then you can get a small-sized car that can be deftly drifted and easily maneuvered. To get such a powerful baby, it is necessary to remove part of the passenger compartment and reduce the length of the driveshaft. You shouldn’t expect significant fuel savings; consumption will decrease, but not as significantly as we would like. Now we need to do the electrical wiring, reinstall the brake lines, carefully close everything up and repaint the improved body. Another drastic solution is to move the spare tire to the trunk lid. But such a design, as they say, is not for everybody.

The body structure can change not only in length, but also in height. Typically, the interior height is lowered by a maximum of 15 cm. This result can be achieved by cutting the pillars, changing the front bumper, and rear lighting. In this case, the exterior changes dramatically. It will not be easy to get used to such dimensions of the car.

If you are lucky enough to drive on perfect asphalt, then you can transform your VAZ-2104 in a rare Stance style. Its essence is to install short springs and small diameter discs. A car with such changes is quite rare, so your VAZ-2104 can become a unique specimen. A more popular type of tuning is body lifting, which is the opposite of Stance. Such a car can easily overcome bad sections of the road and even off-road.

VAZ-2104 in Stance style

The controversial point is the need to strengthen the body support areas. This point cannot be called mandatory, but it is still better if it is implemented. This will definitely not make anyone worse. The installation of rigid springs, which is provided for during the tuning process, requires reinforced metal. For the front suspension, you can choose springs from the Volga, and the rear shock absorbers can be taken from the Gazelle front end.

You seriously need to think about installing air springs that will prevent the body from swaying and make the ride softer. Air springs are installed inside the springs. A similar element can be added to a lifted and standard body, its operation will not change.

Coloring

Body painting is an important element in any tuning. Still, this parameter is most striking and can highlight any car. There are several ways to solve this problem. You can go the standard route and cover the body with regular paint with an interesting effect (metallic, chameleon, matte, glossy). One of the new solutions is liquid rubber. Such painting will not only make the tuned car expressive, but will also protect the body from external influences. Airbrushing can be used not only on expensive foreign cars, but also on models of the domestic automobile industry. It is better to entrust such coloring to specialists who have extensive experience in this field and will be able to transfer any imagination to metal. Airbrushing requires compliance with the declared status, and if you have chosen this method of transformation, then an awkward roof rack, old wheels or a rusty trailer will make the car look ridiculous and tasteless.

Airbrushing makes the VAZ-2104 more expressive

Did not like:

• energy-intensive suspension
• simplicity of design
• low price

• low reliability
• lack of modern comfort
• very high noise level
• poor handling
• lack of active and passive safety systems

View from the outside

I remember how, as a child, I spent a long time looking at this car in pictures. And when my parents gave me a “five” in 1:43 scale, I attached a cardboard superstructure to it, imitating a VAZ 2104. I remember how gradually the car turned from a summer resident’s dream into a working tool for businessmen: the “four” brought milk, welders came. And now this car is considered retro (one of the issues of the magazine “Autolegends of the USSR” is dedicated specifically to the VAZ 2104), but at the same time it enjoys constant popularity.

It’s not surprising, since prices for very real examples start at $3,000. Where else can you find a car with a large trunk, a fairly comfortable and, most importantly, omnivorous suspension, as well as a very low operating cost? By and large, cheapness is the main and almost the only advantage of the VAZ 2104. There are tons of spare parts, and the prices are the envy of everyone, even the owners of old Volkswagens.

Savings are savings, but I didn’t find any other advantages. Moreover, before the start of the test, I treated the “four” with trepidation and respect (of course, many years ago these were the most interesting “Lada” cars to me), and when I found myself behind the wheel, I experienced a shock. A dented seat, a sloppy landing and a gearbox knob that wants to stay in your hand. As you move, the instrument needles shake slightly, no other than out of fear. I’m scared too, scared to make turns on the wheels that are breaking, scared that I won’t be able to brake in time: either you’ll accidentally press the gas, or you’ll catch the mat with your toe. No, you can’t carry people in such a car, but cargo is just right.

When using a large trunk, you constantly bump into a dirty bumper, but a lot of cargo will fit in there, and you are not afraid of getting the fleecy walls dirty. They simply don't exist. There is a shelf above the trunk that rattles when driving. But expensive tools will not attract the attention of thieves. How can you transport someone in a sagging back seat in the summer? I sat down on this and felt like I was wrapped in a fur coat - it was hot.

Now the VAZ 2104 is a working tool and an extremely profitable one. Payback. This is the reason that the streets are full of falling apart “gazelles”, archaic grooves on suburban routes and terrible Chinese trucks. "Four" from the same pack. Buy such a machine for business, and it will pay for itself in a year and a half. Take it for country trips, and it will serve on the farm for 15 years.

PS Having opened and closed the doors several times, I was sincerely glad that in our yard no one drives Russian cars anymore. Someone arrived in such a car late at night, closed the door, and half the house woke up to a loud bang.

VAZ 2104

- a Soviet passenger car with a station wagon body type, developed at the VAZ plant. Serially produced from 1984 to 2012. The model was developed as a replacement for the outdated 2102 station wagon. For some time, 2102 and 2104 were produced at the plant in parallel. When creating a new model, the plant followed the path of least cost and used the VAZ 2105 as the base model. All spare parts were subject to maximum unification. To add rigidity, stampings appeared on the roof of the new model. Unlike the 2102 model, the “four” was equipped with a heated rear window as standard. From the mid-1990s, a rear windshield wiper was included as standard. The base model received the interior from the 2105. The station wagon's load capacity was 455 kg, almost double the maximum load capacity of the 2102. The model inherited the rear door design from its predecessor. Its edge coincided with the floor level, which made loading and unloading luggage easier. The rear seat folds down to create a huge loading area.

VAZ-2104 do-it-yourself tuning

Considering that the design of the “four” dates back to the 70-80s of the last century, we can safely say that the field for work on improving the car is very wide. It all depends only on the flight of your imagination and the availability of funds that are worth spending on it. The main thing is not to overdo it. Generally speaking, improvements can be made here:

• appearance;
• optics;
• engine;
• chassis;
• salon.

Let's briefly look at some options - in fact, there are a lot of them, so a complete list simply cannot fit into the article. If people are greeted by their clothes, then a car is greeted by its appearance. The body shapes of the “four” are clearly outdated compared to the more modern “classmates”. You can change the situation a little by tinting the windows. On this model, they are all straight, without bends, so gluing the film yourself will not be particularly difficult. You just need to spend a little time.

Henry Ford once said that 50 percent of the beauty of a car is its wheels. Accordingly, you can modernize the “four” by replacing the stock steel wheels with light alloy wheels. It is also not recommended to save money here, since we are talking about your safety. Therefore, the main criterion should not be attractive appearance, but the quality of the discs.

You can add dynamism with the help of a circular body kit painted in the body color. However, remember that by doing this you are reducing the vehicle's ground clearance. In the outback, the roads often leave much to be desired, so the risk of leaving part of the body kit on the road, having the loaded vehicle fall into one of the many potholes, is quite high. By the way, about the body color. If you have available funds, you can give your car a more modern look by painting it. It is recommended to use a bright shade of the color indicated in the data sheet. There is another option called airbrushing. An original design on the hood, doors, trunk lid - all this will add originality and attractiveness to your car.

You can also install a more modern radiator grille - for example, with large honeycombs. Some even redo the entire front part of the car. However, such work is very labor-intensive and requires certain skills. If you have never done this before, then it is better not to undertake such processing.

Changing the optics is not only a continuation of improving the appearance, but also increasing driver comfort at night. Xenon headlights make driving at night much easier, and LED angel eyes built inside will change the appearance of the car for the better. Compared to the rather dull stock optics, this is an excellent tuning option, and also relatively inexpensive. Well, you can complement the picture with the help of modern foglights.

The power unit of the “four” also needs tuning. The entire line of engines installed by the manufacturer on the VAZ-2104 does not shine in terms of power. Accordingly, some things here can be improved. The most common option is to increase the volume by boring the cylinders and increasing the piston stroke. If everything is done correctly, you can count on an increase of several tens of horsepower. And the torque will increase. Such work requires some experience. The best option is to remove and install the necessary parts yourself, while the most important work is entrusted to specialists. In order to increase the piston stroke, you must first replace the stock crankshaft. Only after this can you begin installing forged pistons and connecting rods.

The chassis of the “four” is also not the limit of perfection. It is clear that for such a price many owners are willing to put up with the shortcomings. However, some still decide to improve this part of the car. The easiest option is to replace the stock struts with sports struts with double springs. This tuning allows you to feel much more confident on the road.

The spartan interior decoration of the Quartet is also not liked by many of its owners. Meanwhile, there are many possible options for tuning. The first thing a person sees when sitting in the driver’s seat of a VAZ-2014 is a modest, one might even say, spartan dashboard, which is also quite dimly illuminated by the standard backlight. The most radical option is its complete replacement. Choosing a different, more modern instrument panel will not be difficult, and the appearance of the interior will then change for the better, especially at night.

Vehicle optics

Let's now look at the car's headlights. Do they really not look very good, standing out with their “sad look”? It would be best to install lensed headlights on your car. Such optics will not only give your car a noble appearance, but will also help preserve the vision of drivers who will be driving towards you, and will reduce the likelihood of accidents due to blindness. You will have to spend money on new headlights, but they have low power consumption, but high light output, and as a result you will only benefit. The only thing is that lensed headlights need to be installed correctly, without various distortions, so it is better to contact professional car mechanics. They have certainly done tuning for the VAZ-2104 many times and will advise which brand of headlights will suit your car. If you want to Americanize the car, we recommend installing truncated red taillights.

So, as you can see, there are plenty of opportunities for tuning. It is not necessary to change everything in the car at once; you can tune it as much as possible. Maybe you will enjoy this process so much that you will become a real tuning professional. Many car enthusiasts do not specifically buy new cars, because they prefer to improve legendary cars and drive them. The main thing is to do everything professionally and slowly. As they say, if you hurry, you will make people laugh. The car must be trouble-free, all systems must be adjusted, then you can safely drive it, but whether to tune the car or not, everyone must decide for themselves. In any case, we recommend that you undergo a full diagnostic at a car service center to once again make sure that your car’s systems are in order, and you will not unwittingly become the culprit of an accident.

Have a nice trip with your new rare car!

Improving performance when repairing a VAZ 2104

A beautiful car attracts attention, but real car enthusiasts are interested not only in the outer shell - the internal “filling” is also of great importance to them. Since the “four” appeared a long time ago, it is not up to par with modern cars, but the car can always be modified

To increase the speed of the car, you should work on its suspension - with the correct suspension settings, you can achieve colossal speed characteristics. If you replace the standard struts with sports struts, the car will stay on the road much better, regardless of whether it is driving on hard or soft road surfaces. Sports suspensions are distinguished by the fact that they are equipped with double springs and can also be adjusted as needed.

Engine tuning allows you to increase its power. Motorists often perform so-called cylinder boring to increase the power of the power unit. This is done like this: the cylinder walls are simply bored to the required thickness, as a result of which the engine power increases.

You can also purchase a new crankshaft, with a large eccentricity, and replace the standard unit with it. It is imperative to select suitable connecting rods with pistons - such a repair of the VAZ 2104 will also increase the engine power, as well as its efficiency.

Often, car enthusiasts resort to so-called chip tuning, in which the engine control unit is reconfigured, that is, it is replaced with another one. As a rule, “sports” is used as a new “firmware”, which is “tailored” for a specific power unit. This method of upgrading the engine is inexpensive and takes little time - which is why it has become the most popular.

In addition, car enthusiasts often install a turbocharger with a low-resistance air filter.

When modernizing and repairing a VAZ 2104, you should also change the ignition system - the standard ignition system of the “four” has a number of disadvantages, it has long been outdated, so it is best to replace it with a contactless ignition system at the first opportunity. After such a replacement, the engine will start much faster in cold weather, the dynamics of the car will increase, the reliability of the car will increase, and the air-fuel mixture will burn more completely, and accordingly, the CO content in the exhaust will decrease.

What else can you change?

As an option, the VAZ-2104, which many people tune on their own, can be shortened.

The truncating of the body turns the already not particularly bulky car into a maneuverable small car, which is not afraid of all narrow alleys and traffic jams. As an experiment, some craftsmen transfer the spare tire to the trunk lid. The procedure for shortening a car itself consists of several basic operations:

1. Cutting out part of the passenger compartment.
2. Reducing the length of the driveshaft.
3. Re-installation of electrical wiring and brake system.
4. Painting and polishing the resulting masterpiece.

In practical terms, reducing the length of the vehicle of the brand in question will allow you to save a little on fuel consumption, and the external transformation will surprise and delight many road users.

In addition, you can update the optics of the “four” by replacing them with xenon lenses with LED “angel” input. Having worked a little magic on the shape of the trunk, it is possible to mount shortened rear brake lights, like American cars. A pneumatic cushion installed in the inner part of the spring will reduce body sway and increase the softness of the ride. Similar elements function as with standard car equipment.

Four directions of tuning VAZ 2104

In fact, there are most likely more than four directions, but we will consider exactly four in order to support the numerology of this model:

1. A solid classic. In this role, the VAZ four looks really respectable. Reducing detailing, painting in an interesting but calm color, lengthening the body, installing chrome wheels - all this works for a solid image;
2. Sport style. It must be said that the task of making a sports car out of a “country car” is extremely difficult, but many tuners are not looking for easy ways. These are the types of challenges they enjoy most. However, you will have to do a lot of work, since the angular body needs to be made streamlined;
3. In retro style. The design of the VAZ 2104 can be redesigned in retrospect. Smooth expansion of the arches, rounding of the headlights, welding of the sills, styling inside the cabin - these are just some of the changes that can be used;

Hull modernization

We come to the most interesting part - tuning the car body. You can take a walk here. Let's start with the glass. They can be tinted with a special film. The film is sold in any automotive stores. Even an inexperienced craftsman can apply the film. Just buy a quality product so as not to be disappointed with the result.

Some parts of the car can be chromed, which will also significantly affect the appearance as a whole. And it is best to install rare caps on the wheels. Your car will be recognizable from afar!

You can also change the car body. Nowadays a huge number of attachments are sold: skirts, bumpers, spoilers. Buy lightweight parts made of carbon plastic so as not to make the car heavy. If you select the parts correctly, then the work of upgrading the body can be quickly and successfully completed.

To give the four a modern look, its body can be painted. You will have to go to automotive stores again for paint. The choice of coatings is limitless. You can choose any paint that suits your taste. Chameleon paints are also sold, which give cars a rather original look. You can choose paint from a Russian or Western manufacturer in any price category. You are limited only by your wallet. Don't forget to purchase a solvent. Before painting, the car should be cleaned, sanded and the windows covered with masking tape to prevent paint from getting on them. Then get to work. You will have to apply the paint in several stages, allowing it to dry completely after each applied layer. You should achieve a smooth, even finish.
