Body geometry of the VAZ 2107 with dimensions

Body weight of VAZ 2107

The weight of the VAZ 2107 body is of great importance not only in terms of the performance characteristics of this car, but also directly affects the dynamics. In the era of “weight loss” fashion, when miniaturization has swept the entire global auto industry, the “seven” cannot remain aloof from all this. Reducing the weight of a car without changing its linear dimensions is what designers and car owners dream about today. The goal of the problem is clear - to improve acceleration and save on fuel, but there may be several methods for solving it. And on the VAZ 2107, the body dimensions can remain intact, while the weight of the car can be reduced. We will find out from the article how much the “seven” weighs, how you can lighten its body without changing its dimensions, and what achievements the car is capable of after that.

Car body

The body of the VAZ 2107 car is a rear-wheel drive four-door sedan. The assembly diagram of its frame is standard and has the following elements:

• Front parts;
• Front fenders with reinforcements;
• Roofs with glass frames;
• Reinforced floor and rear panel;
• Side parts;
• Hind wings.

Each element is cast from mild steel. Each part has not only its own number, casting pattern, but also its own thickness. For example, for the roof it is 0.9 mm, and for the rear wheel arches - 1.0 mm.

Most parts are connected using non-contact welding, but parts that bear a large load are additionally strengthened by arc welding.

Among the mounted parts it is worth highlighting:

Dimensions and specifications

Regardless of the configuration, the VAZ 2107 has the following dimensions:

- curb weight (how much is the weight of the car with equipment and materials) - 1030 kg,

- total weight (how much does a loaded car weigh with passengers and cargo) - 1430 kg

A motorist needs to know not only the standard parameters of his car, but also the control dimensions.

Control dimensions (points) are usually necessary when restoring a car after an accident. If you buy a used car, knowing these control dimensions, you can easily find out whether the car has been in an accident. This geometry will help in restoring the body, as well as other important parts.

The main control dimensions are described in detail in the diagram below:

The linear dimensions are clearly defined by the following diagram:

Identification data

The VAZ 2107 car, like any other car, has specific passport data, the liver of which is indicated in the table located under the hood on the air box.

The plate contains information about the vehicle model, engine number and body number, weight data and spare parts number. Above it is the vehicle identification number - VIN.

— The first 3 letters are responsible for the manufacturer’s code;

— 6 subsequent digits are the decoding of the car model;

— A letter or number of the Latin alphabet indicates the year of manufacture of the VAZ 2107 model;

— The last 7 digits are the required body number.

You will find the exact same number in the trunk.

Hood

Part of the body of the “seven”, covering the engine compartment. This is the main purpose of the body element: to protect the “heart” of the car from the influence of the external environment and protect it from prying eyes. The hood also has another purpose, albeit a secondary one:

• The aerodynamics of the car to some extent depend on the hood;
• The hood improves air flow to the engine. The air flows directionally and better through special air intakes and additional type of slots made in the hood;
• The hood is able to absorb the hum and slight shaking that the internal combustion engine produces during operation. This is especially noticeable at high speeds.

The connection to the body of the VAZ 2107 is carried out with hinges and bolts. The hood itself consists of 2 panels connected to each other by edge rolling followed by welding. All seams and joints are carefully sealed with mastic.

Note. The hood on the VAZ 2107 can be adjusted. For this purpose, enlarged holes are provided in the hood hinges.

The price of a hood individually, as a rule, does not exceed 2.5 thousand rubles.

Famous pickup truck

For those who were looking for a spacious, convenient option, a pickup truck in any color was produced based on the VAZ 2107. It is called the VIS-2345 pickup, but it is also no longer produced. But despite this, it is still popular.

This subcompact pickup truck is easy to drive, giving you plenty of flexibility to haul as much stuff as you need. Even a refrigerator will fit into the wide isothermal booth.

The two-seater pickup truck has a fuel-injected engine. It reaches speeds of up to 110 km/h. Due to its convenience and original design, this body type is very common in America and Europe - so it’s a shame that production of this model was stopped.

Body replacement

The VAZ 2107 sedan or pickup truck has not been produced for several years, but drivers can still purchase bodies for their cars if necessary. If you suddenly get into an accident, or the body of your car is in disrepair, you can easily order a new one.

The action plan is simple. First, you will need to decide on the necessary equipment, as well as what type of body you need.

One package includes a new “body assembly”, which includes electrical appliances, wiring, glass, front and rear bumpers;

The other configuration is called “body in metal”. It includes a new body painted in the desired color and treated with anti-corrosion agents.

The factory provided various colors for the VAZ 2107. Each of them has its own name. For example, pale yellow is “melon”, classic red is “viburnum”, and marsh green is “Sochi”.

When ordering a body in the third configuration, you can make it in any color. It may take longer than if you had stuck with plain white paint. But a car with a bright, noticeable color will always be fun to drive.

Facing panel (apron) and front bumper

The facing panel or front apron on the “seven” plays more of a decorative role. But besides giving a stylish appearance, an apron also provides many benefits. In particular, thanks to it, during rain, water does not fly directly onto the windshield, but is cut off by this element.

The apron is located directly under the bumper and is a flexible shield that also serves to prevent damage to the front of the car from splashes from under the wheels.

This structural element of the body has special holes for the front bumper brackets and the radiator grille (the latter is attached to it). The apron, due to its “extreme” location (bottom and front), becomes vulnerable to impacts and corrosion. Connected to the body by spot welding.

The design of the "seven" apron must be thought out carefully and correspond to the shape and geometry of the entire car body, otherwise it will simply vomit at high speed. In addition, non-compliance with geometry and design will lead to increased fuel consumption at high speed.

The price for a front apron for a VAZ 2107 individually starts from 600 rubles. The part may be of different workmanship, have a different color and different design features.

Front aprons, sold as a separate element of body decor, come with special mounts to the bumper. As for the original Semerovo ones, they are welded, as mentioned above, to the car body.

The rear apron is also required and must have special fastening plates that ensure its immovable condition and prevent it from coming off on the road.

Front bumper

The bumper is not only designed to retain the energy of a frontal impact first, but also plays a significant role in the exterior design of the Seven. In other words, this is a beam located in front and protects the body from damage in minor collisions.

Thanks to modern synthetic-based materials, bumpers have become much lighter and more beautiful than they were before. Thus, elegant bumpers with bent edges also serve as spoilers, increasing the downforce of the car.

The front and rear bumpers on the VAZ 2107 are made of plastic or thin metal and have chrome trim. They are mounted using special brackets.

The front bumper is equipped with a platform for attaching a license plate and for this reason is 5 cm wider than the rear one.

Today, the owner of the “Seven” is offered three options for bumpers for the VAZ 2107: plastic, plastic with chrome lining, and with brackets for fastening. The price starts from 600 rubles.

Front bumper tuning

Modernizing the front bumper of the “Seven”, first of all, means improving the appearance. To be honest, the factory bumpers of the VAZ 2107 family look, to put it mildly, fake. They do not carry any visual, or even more importantly, high-quality functionality.

The implementation of the idea of ​​tuning the bumper on a VAZ 2107 (the rear one is also possible) consists in strengthening it with a metal profile of an L-shaped section. In addition, to give a more aesthetic appearance, the part moves slightly from the body.

You need to work with the bumpers removed. Here's what to do:

• Place the pre-prepared reinforcing corner to the bumper and mark the mounting holes, and then drill them in the profile;
• The lower part of the profile bends forward. This creates a fastener for the lower bumper bolt;
• First, the amplifier is attached to the body, then the bumper is attached to it.

As a result, we get a massive bumper that is not afraid of light and medium impacts and looks much more impressive in appearance than the factory one.

Characteristics of the VAZ 2107 body

The body of the VAZ 2107 not only has contours similar to all classic VAZ models, but also a number of characteristic features.

Body dimensions

The VAZ 2107 body has the following dimensions:

• length - 412.6 cm;
• width - 162.0 cm;
• height - 143.5 cm.

Body weight

There is a distinction between the mass of a clean body and the mass of a body with equipment and passengers. These parameters for the VAZ 2107 are:

• clean body weight - 287 kg;
• curb weight (with all equipment and materials) - 1030 kg;
• total weight (with all equipment, materials and passengers) - 1430 kg.

Body number location

The body of any car has its own number. The VAZ 2107 body data plate is located under the hood on the bottom shelf of the air intake box.

The same plate contains information about the engine model, body weight and vehicle equipment, and the VIN code is stamped next to the plate.

Basic and additional body elements

There are main and additional body elements. The main elements include:

• front part (front);
• rear part (rear);
• wings;
• roof;
• hood.

Additional elements of the VAZ 2107 body include mirrors, linings (moldings) and some other parts. They are all made of plastic, not metal.

Mirrors

The mirrors are designed to provide the driver with complete control over the road situation. They are often damaged because they extend beyond the dimensions of the body and, if driven carelessly, can hit various obstacles.

My bitter experience of driving for the first time, when I was 17 years old, was connected precisely with mirrors. How many times did I interrupt them when I tried to move in or out of the garage? Gradually I learned to drive carefully. The side mirrors remained intact, even when parking in reverse between two closely parked cars.

The side mirrors of the VAZ 2107 are mounted on a rubber gasket and fixed to the door pillar with screws. By modern standards, the standard mirrors of the 7 are not distinguished by a successful design. Therefore, they are often modified to improve appearance, increase functionality and increase viewing angles. Part of the space around the VAZ 2107 (the so-called dead zone) remains invisible to the driver. To minimize this area, spherical elements are additionally installed on the mirrors, significantly expanding the view.

Residents of the northern regions often tune heated mirrors. To install the system, a self-adhesive heating film is used. It is freely available. You can install it yourself, just arm yourself with a screwdriver, a ruler, wires and masking tape.

Moldings

Plastic door sill covers are called moldings. VAZ 2107 owners usually install them themselves. This is quite easy to do - no special skills or special tools are required. Moldings perform exclusively decorative functions. Some craftsmen make them with their own hands, constructing something like a body kit. However, it is much easier to pick up ready-made overlays in the store or leave standard decorative inserts.

Moldings must meet a number of requirements.

1. Moldings should not be made of very hard material such as fiberglass. Otherwise they may crack.
2. The material of the moldings must withstand temperature changes and be inert to the effects of chemicals that are sprinkled on roads in winter.
3. It is advisable to purchase moldings from a reputable manufacturer.
4. There should be no gaps between the molding and the threshold, otherwise the thresholds may corrode.

General view

ATTENTION! A completely simple way to reduce fuel consumption has been found! Don't believe me? An auto mechanic with 15 years of experience also didn’t believe it until he tried it. And now he saves 35,000 rubles a year on gasoline! Read more"

The exterior of the “Seven” generally copies other VAZ models, called “classics”. On the other hand, some parts and components of the frame are not the same. They simply will not fit the general exterior due to the fact that they differ in basic parameters.

Let's start with the front. This area of ​​the car includes these components: the hood, the apron with the front bumper (they are considered more decorative elements) and the fenders.

As for the middle part of the car, this includes the roof of the VAZ 2107, sills, and doors.

Finally, the rear of the car includes the fenders, boot lid and rear apron.

All main body elements are made of stamped steel, additional ones are made of plastic. If minor damage occurs, they can be easily straightened and, if necessary, replaced with new ones without much difficulty.

Note. With the exception of the “tail”, all elements of the “Seven” body are connected by welding.

Comparatively, the “seven” looks more modern than other “classic” models. It is for this reason that the car remained on the production line, although the designers did not make any significant changes.

The car interior is equipped with 4 seats. The front seats are made in the form of an independent adjustable design. As for the rear ones, they have no adjustment. The interior lining is plastic, the roof is covered with leatherette.

The interior of the “Seven” is structurally excellently protected from frontal and rear impacts, but a side collision with another car can lead to catastrophic consequences.

VAZ 2107 body repair

Almost all experienced VAZ 2107 owners know the technology of body repair. This allows them to save on service station costs and extend the life of the body. The repair involves a number of measures to improve and modernize the skeleton.

For body work you will need the following tools.

1. A chisel with a sharp tip.
2. Bulgarian.
3. Clamp or pliers for holding new parts in place before welding or bolting.

Installation of plastic wings on a VAZ 2107

The main task of the wings is to protect the interior from dirt and stones entering through the open glass when driving. In addition, they improve aerodynamics. It is the wings of many cars that are most often restyled and take on a more streamlined shape. The wings of the VAZ 2107 are an element of the body and imply the presence of an arched cutout for the wheel. They are attached to the body by welding. Sometimes, to reduce the weight of the car, the front metal fenders are replaced with plastic ones. Moreover, plastic is not subject to corrosion. On the other hand, plastic fenders are less durable and may break in a collision.

It is not difficult to purchase a plastic wing for the VAZ 2107. You can even do this through an online store with home delivery. Before installation, you must first remove the metal fender. To do this you need:

1. Use a sharp chisel to disconnect the wing at the welding points.
2. Pull out the wing.
3. Using a grinder, clean off the remains of the wing and welds remaining on the body.

To install a plastic wing, you need to perform the following steps.

1. Apply a layer of special automotive putty to the joints between the plastic fender and the body.
2. Secure the plastic fender with bolts.
3. Wait for the putty to harden.
4. Remove the mounting bolts from the wing.
5. Remove excess putty from the edges of the wing that was squeezed out during installation.
6. Lubricate the wing with a layer of graviton and laminate.
7. Putty the entire structure and paint it in body color.

I would not recommend installing a plastic fender. Yes, it allows you to lighten the body, but at the slightest collision of the car with other cars, you will have to change the part again. Many Japanese, Korean and Chinese cars have such plastic parts installed. Any minor accident forces the owner to order expensive repairs.

Welding the body of a VAZ 2107

Typically, damage to the body of the VAZ 2107 is associated with corrosion or is a consequence of an accident. In these cases, it is optimal to weld with a carbon dioxide semi-automatic machine, which uses wire to connect individual elements. Electrode welding is not recommended, since it is almost impossible to make a high-quality seam on the body with its help. Moreover, electrodes can burn through thin sheets of metal, and the device itself is large and does not allow working in hard-to-reach places.

Threshold repair

It is recommended to begin restoring thresholds by inspecting the door hinges . If the doors are sagging, it will be extremely difficult to establish the correct gap. It is also inappropriate to restore an old threshold corroded by rust - it is better to immediately replace it with a new one. It is recommended to perform the work in the following order.

Cut off the outer part of the threshold with a grinder or chisel.

The threshold amplifier can be made independently from a metal strip. It is necessary to make holes in it in the middle of the tape with a hardened drill every 7 cm. You can fix the part before welding with a clamp or clamps.

When welding a threshold, you must perform the following steps.

1. Weld the reinforcement with two parallel seams - first from below, then from above.
2. Thoroughly clean the weld seams to a mirror shine using a grinder.
3. Try on the outer part of the threshold. If there is a discrepancy, trim or bend.
4. Remove transport soil from the new threshold.
5. Coat the inside of the threshold with an acid or epoxy compound.
6. Secure the threshold with self-tapping screws.
7. Hang the doors.
8. Check the gap size.

The new threshold must be located strictly in the door arch, not protrude anywhere and not drown. After a careful inspection of the gap, welding of the outer part of the threshold begins, doing this from the middle pillar in both directions. Then the threshold is primed and painted to match the body color.

My brother-in-law is a bodybuilder. He always advised me and my friends to pay attention to the thresholds. “Remember, the car is rotting from now on,” Vadim said, lighting a cigarette during a break, pointing with a yellow finger at the bottom of the doors. I was convinced of this from the experience of operating the “Seven” when I was repairing the body. The thresholds were completely rotten, although the remaining areas remained untouched by corrosion.

Underbody repair

The underbody is more exposed to aggressive environmental influences and mechanical damage than other elements. The poor condition of the roads also has a noticeable impact on its wear and tear. Therefore, the bottom often has to be completely digested. You can do this yourself - all you need is an inspection hole or overpass and good lighting to inspect the bottom. Tools you will need:

• gas welding or semi-automatic welding machine;
• metal scissors;
• Bulgarian;
• straightening hammers.

Part two. Corrosion

Causes of corrosion and sources of its damage Corrosion is the process of self-destruction of a material in the process of interaction with the environment. In our case, metal corrosion occurs due to:

• Winter “urban” operation;
• Cheap body restyling, under which all kinds of dirt accumulates;
• Storing the car in damp, unventilated areas.

Places of the VAZ 2101 body most susceptible to corrosion

As the experience of most car owners shows, parts of the VAZ 2101 body that are most susceptible to corrosion are located in hard-to-reach places where moisture does not evaporate for a long time (gaps, bends, flanges), namely:

• wheel arches;
• hinged elements and places of their attachment (hood, trunk, doors, sills, fenders).

And if no measures are taken, then it can move to other, more significant power elements (spars, joints of the sub-engine frame, central pillars, etc.). Depending on the degree of surface destruction, it depends on how we will restore the damaged part.

Stage one

The oxidation process is in the initial stage (chips, scratches), only a slight color change has occurred. At this stage, you can get by with small losses - cleaning the surface with a fine abrasive wheel and then polishing the surface.

Stage two

Both the color of the paint changes and its swelling occurs, that is, the destruction process occurs evenly over the surface of the element.

Corrosion of the rear wheel arch of a VAZ 2101

This type of corrosion is not so terrible; it most often occurs due to poor preparation of the element for painting. It can be relatively easily cured by repeated stripping and subsequent filling with cold-set epoxy mastic. This type of mastic has high strength, sufficient adhesion, and is easy to apply to the damaged area. It contains plasticizers and hardeners, which increase the plasticity of the resin and its impact strength, as well as fillers that reduce the shrinkage of the resins and ensure that the coefficients of thermal expansion of the metal and the resins are brought closer together.

Hood of VAZ 2107

VAZ 2107 owners often modify the hood of the car. First of all, the lid stop, which was made at the factory in an extremely inconvenient way, changes. First you need to remove it from the latch and only then close it. On the VAZ 2106, the same stop is designed much simpler and more functional.

Installing an air intake on the hood

An air intake or snorkel is often installed on the hood of the VAZ 2107, which improves the appearance of the car and helps cool the engine. It is mounted so that air flows directly onto the air filter. Sometimes additional pipes are installed to the main air intake to increase cooling efficiency.

The snorkel is usually made by hand. In this case, it is better to use durable plastic or metal as a material. The air intake is mounted as follows.

1. A U-shaped hole is cut in the hood with a grinder.
2. The cut out part of the hood is bent to form the snorkel profile.
3. Triangular metal pieces are welded along the edges to cover the ends of the part.
4. The hood is puttied and painted to match the body color.

When cutting the hood, it is important not to touch the stiffeners provided by the design. Otherwise, the strength of the body will noticeably decrease.

Hood lock

Sometimes car owners modify the hood lock of the VAZ 2107. If it does not work well or fails, the mechanism is dismantled. It is recommended to first outline the lock with a marker - this will avoid adjusting a new or restored lock. The mechanism is removed in the following order.

1. The hood opens.
2. The lock cable clamps come out of their seats.
3. The bent end of the cable is straightened with pliers. The fixing sleeve is removed.
4. Use a 10mm wrench to unscrew the lock nuts.
5. The lock is removed from the pins.
6. A well-oiled new lock is installed.

When replacing the cable, it is first disconnected from the lever handle. This is done from the salon. Then the cable is pulled out of its sheath. Nowadays, cables are often sold complete with a sheath. In this case, when replacing the old cable, it is pulled out along with the casing.

Is it possible to install r14 wheels on a VAZ 2107 - Autosite

One of the most common types of external tuning of VAZ 2107 cars is the replacement of standard stamped wheels with cast ones

Such tuning can dramatically change the car, giving it a more modern design. Besides being cast

One of the most common types of external tuning for VAZ 2107 cars is replacing standard stamped wheels with cast ones. Such tuning can dramatically change the car, giving it a more modern design.

In addition to the fact that alloy wheels look much more beautiful than standard ones, they also allow you to significantly change the driving characteristics of the VAZ 2107. This becomes possible thanks to the availability of alloy wheels of both R13 and R14 sizes on the automotive market. They can be installed without any modifications to the vehicle.

You can also install 15-inch wheels, but you will have to use thin-profile tires on them. In addition to the diameter of alloy wheels for VAZ 2107 cars, many tuning studios offer the installation of wheels of different widths and offsets

However, you shouldn’t get too carried away in this matter, since if you install new alloy wheels with a larger offset compared to stock, this threatens rapid wear of the bearings on the hubs.

And the car’s suspension will also deteriorate noticeably faster. In addition, do not forget that such wheels, or rather their outer side, will be located outside the fender liners and mudguards, and as a result, almost all the side surfaces of your VAZ 2107 will be splashed with dirt.

In addition to the above-mentioned sizes, you can also install even larger wheels during tuning. But such a procedure requires alteration of the wings, and sometimes the suspension. But you will definitely have to cut out larger arches in the wings. In addition, when using wide alloy wheels, it is possible to expand the geometry of the wing due to special linings.

However, most experts and VAZ 2107 owners do not recommend installing wide and large rims

Since, along with problems in the suspension, your car will noticeably increase fuel consumption. Therefore, the most optimal option for installing alloy wheels on a VAZ 2107 are R14 wheels.

The same kind of trends are present when installing alloy wheels on the VAZ 2110. But as for other cars and brands, we will look at them a little later

Since, for example, alloy wheels for the GAZ 3110 will differ significantly from VAZ wheels both in size and configuration.
