At the end of last week, we visited a completely fresh Lada Granta, which we did chip tuning. Engine 1.6 with 8 valves and 87 hp. The exhaust system was replaced with a kit from the Stinger, so Euro-2 firmware was required with modified fuel supply schedules, OZ, etc.
Lada Granta cars were equipped with M74 units with K-line or CAN interfaces. We will program this unit by removing it from the car and connecting it on the table. What’s noteworthy is that the unit has a CAN bus, but “wanted” to be programmed only via K-Line.
For work we will use the original J2534 Openport 2.0 adapter, a universal Combiloader cable and a bootloader from the same manufacturer.
Chip tuning of Lada Granta/Kalina/Priora engine, reviews
Engine tuning (chip tuning) allows you to change its behavior.
For example, the car will become “faster”, pick up speed better and accelerate more dynamically from a standstill. The power will increase, which will allow you to overtake and maneuver faster. The gas pedal will become more responsive and fuel consumption will decrease. All this is promised by the masters who are engaged in chip tuning of Lada cars, but is this really so? To answer this question, we decided to turn to the reviews of drivers who had their Lada Granta engine chip-tuned.
1. The author of this video tells the first impression:
According to him, before chip tuning, the Lada Granta was a little sluggish, the gas pedal response was slow. After tuning the engine, the car began to drive simply amazingly, it just “came to life.” In the races it is not inferior to Renault Logan and Hyundai Getz. Fuel consumption has not increased. The author also shows how, after chip tuning, his car began to accelerate (up to 100 km/h in 10 seconds).
It is worth noting that the majority of channel users did not agree with the review. They did not notice improved dynamics during overclocking. The price of chip tuning was unreasonably high, and they were dissatisfied with the results after tuning the engine.
2. Another video review about chip tuning of a Lada Granta with an automatic transmission in the “luxury” configuration. The driver immediately notices the difference after replacing the factory engine software. If previously the speed switching occurred at 4500 rpm, then after adjustment the switching occurs already at around 5000-5500 rpm. The response to the gas pedal has become faster. The power has increased, which allowed the Lada Granta with automatic transmission to slip. The driver was pleased with the work done.
And again, the main audience does not agree with the author’s opinion. They claim that 5500 rpm “turns” even without firmware, grinds without problems, sometimes even on the second. It is worth noting that both video reviews were published for advertising purposes, as evidenced by the name of the author and the advertisement during viewing.
Thus , the real review about chip tuning of the Lada Granta was formed from the comments on the video. The majority of users do not share the opinion of the authors of the videos and prefer not to change the factory firmware of the engine. Do not forget that there are many firmwares that allow you to approach chip tuning of each car individually. And what the result of replacing the software will be depends on the specialist.
Help determine the need for engine tuning by participating in the survey. Tell us about your experience of chip tuning on Grant, Kalina or Priora. Let us remind you that on the site you will find other ways to do car tuning yourself.

Should I flash the 8 valve grant or not?
It’s still better after a full run-in. It’s generally better not to turn the engine until 2-3 thousand km (some don’t turn it even up to 5 thousand). The optimal way is to go through TO-0 (you can do it ahead of schedule - I had it done by an “unofficial” after 3000 km) and fill in normal synthetics, adjust the valve clearances, and check the compression of the cylinders. The fact is that the Grants coming out of the factory are, to put it mildly, of “uneven” quality.
That is, if you really want to get results from chip tuning and new driving pleasures, you should first put the car in order. Then there will be more pleasure and less disappointment!
Added after 20 minutes the power does not increase. You can increase the cyclic fuel supply, for example, change the quality of the mixture in certain engine operating modes, and the most important thing is to turn off the lambda probes, which greatly choke the engine and, believe me, the car will accelerate an order of magnitude faster. from myself: I had 2 21124, one chip, the second standard. So that’s the chip when you’re driving in 1st gear at idle and your sneaker is on the floor, it feels like it’s about to take off, the wheels are jumping. On standard it accelerates stupidly. It was also done that after 3000 rpm it became much more active to drive. But one thing I didn’t like was that after the firmware, if you open one window, when you sharply press the gas, the cabin smelled of gasoline. I don’t know why, probably the engine received a heavy dose at that moment in order to accelerate was more intense. Added after 1 minute Of course, the power cannot be increased, but the firmware can be corrected so that it meets the requirements set by the client; if you want it more sporty, please, if you want lower consumption, this can also be done. In addition, it was noticed that with slightly tuned firmware in the direction of greater acceleration dynamics, fuel consumption was often reduced (slightly), I don’t know how it all worked out, but it’s a fact. Well, by and large, a banal change of firmware may not bring the desired result, if everything is done correctly, then the firmware needs to be “tested” in all possible engine operating modes and the calibration tables edited, and then the result will be. And the reason for this is that the firmware is written for an engine with average parameters, and given the quality of our spare parts (even those supplied to the assembly line), the result is different.

Dynamics
External view of engine 21116
This is not a racing car, but there is enough power for both city driving and highway driving. If we compare it with the 16-valve engine of the Lada Granta, which is installed on the Luxury versions, then it has more torque at the bottom. This means that you can drive in 5th gear at a speed of 40 km/h.
For example, you are driving at 5 speed, the traffic light in front lights up red. You release the gas pedal and the car brakes with the engine. The light turns green and you can continue driving in 5th gear even if the vehicle speed has dropped to 40 km/h.
I was pleasantly surprised by the elasticity of the motor. Considering that I previously owned a Priora, and it has a 98 hp engine, then the engine is 87 hp. I like grants better.
What will happen to the dealer's warranty?
In most cases, nothing happens to the warranty:
- Firmware changes are difficult for many car dealers to detect. This does not happen during maintenance.
- If the dealer discovers that unofficial software is installed, he will replace it. According to the Law “On Protection of Consumer Rights” he cannot refuse service.
- Official dealers themselves offer ECU reprogramming services.
If you are afraid of losing your warranty, you can fill the drain before going to the dealer.
What to expect from ECU tuning
Reflashing allows you to correct errors and optimize the performance of the car.
Companies offering chip tuning services develop and offer various software that allows you to optimize the basic performance of cars.
This process allows you to correct all sorts of errors, create a backup copy of the initial settings, study and adjust characteristics, as well as make changes and test new firmware of electronic components.
If you need to return to default settings, this is done almost instantly. But those who have already reflashed Granta will never return to the standard factory settings. After flashing you can get:
- reduction in fuel consumption by 5%;
- high speed characteristics;
- 10% increase in power;
- smooth operation of the automatic transmission;
- improved traction.
And that's not all. In this case, not a single intervention is made in the mechanics. This is one of the cheapest ways to make Granta better. There is one caveat. If the car is currently under warranty, after flashing the ECU, the warranty is invalid.
What you need for firmware
In order to flash the electronic engine control unit you will need several essential things.
Attention: if a car enthusiast has never carried out brain flashing operations, then it is not recommended to do it yourself. Since an incorrectly performed procedure can lead to catastrophic consequences, such as the ECU failing, the car will not start, or even an electronic part will fail and require replacement, which in some cases will significantly hit the owner’s wallet.
Self-reflashing the ECU will require the following resources:
- A laptop, tablet PC or a special computer used by experienced auto electricians and tuning specialists.
- Software according to the vehicle.
- Directly the firmware software of the corresponding version.
- OBD II or K-line cable. Recently, in order not to carry wires, wireless connection via Bluetooth channels has become popular.
- Well, the last, important factor is the presence of brains and hands growing from the right place.
Engine Features
Due to the design of the car's cooling system, the engine does not warm up above 80 degrees. The management of AvtoVAZ does not see anything wrong with this; they have an official information letter on this matter. You can read it in the material: What is the operating temperature of an 8 valve engine.
The engine design is as simple as an axe. There are no hydraulic compensators, no sores were noticed. Mostly problems can arise due to malfunctions in the engine management system.
Video of acceleration to 100 km per hour
I haven’t shot my video yet, it’s winter, so we’ll wait for the weather to warm up. That's when I'll post it on our YouTube channel. In the meantime, here's a video from Grantovodov.
Here's another interesting video. It is interesting because the measurement is made using an application with a navigator , which means that the speedometer readings are more accurate if the navigator is well calibrated. Everyone knows that the higher the speed, the more the car’s speedometer lies.
Automatic transmission error codes
Automatic transmission malfunctions, ways to eliminate them
Characteristics and differences of JATCO automatic transmission
After the merger of Nissan and Renault, the latter began to be equipped with Jatco transmissions. This once again confirms the high quality and reliability of the units.
Jatco gearboxes are installed on both economy class cars and mid-range models. For example:
- Lada Granta: JF 414E with four speeds;
- Daewoo Matiz, Kia Picanto: JF 402 / 405E.
The main difference between a gearbox is its simplicity of design, maintenance and reliability. The header on the domestic market is represented by an automatic transmission and continuously variable transmissions (Tiptronic).
The machine is based on a complex control system at the level of solenoids and valve body.
For the first time since 2011, Reaper boxes are equipped with solenoids made of a special material that is unpretentious to the quality of transmission fluid.
This made it possible to change the oil less frequently, increase the service life of the fluid and save some money. Preventive maintenance of the unit is carried out every 75-85 thousand km. Cleaning elements must be replaced within the specified interval.
Reasons that require modification of the Lada Granta ECU
As mentioned above, VAZ equipped the new 2190 with an M74 controller 11186-1411020-12. The essence of its functioning is radically different from earlier models, i.e. other blocks and reprogramming methods do not work here. Data transmission is carried out via the CAN bus, which has a higher speed than the K-channel of previous versions.
A car with factory settings generally satisfies many drivers, but some still decide to update the ECM for several reasons:
- the engine does not maintain idle speed when the air conditioner is on;
- difficulty starting a cold engine;
- incorrect temperature conditions;
- engine stop;
- lacks dynamics;
- excess fuel consumption.
A VAZ 2190 with an automatic transmission at medium speeds experiences some difficulties in choosing the appropriate speed - the automatic transmission is constantly trying to switch to a lower gear. For an urban environment with little traffic, this solution is not critical, but on the highway or in heavy traffic it will be problematic to maneuver.
There are also numerous comments regarding the lack of smooth transitions and weak traction at the lowest revs. Experts agree that the factory workers did not finalize the parametric characteristics of the controller a little. From this we can conclude that any self-respecting driver should still make adjustments to the program.
Who develops firmware tuning
There are factory and custom firmware
Firmware is divided into two types: factory and tuning. The first ones are developed by automakers or their court companies (for example, Volvo Polestar, Nismo). The second are large private workshops (for example, Revo, which develops firmware for Volkswagen cars) or individual craftsmen.
Global brands such as Mugen and Revo only tuning certain brands of cars, and their approach is very different from non-professionals. As soon as a new engine appears, such companies purchase a car with this engine and send it to their software engineers for modification. It takes months to create tuning firmware. At the same time, several versions are being developed at once, and each of them is tested in different situations: highway mode with a partially open throttle, city mode (gas-brake), endurance testing and track mode, when all systems work at the limit of their capabilities. If the company is confident in the firmware, dealerships offer customers (with their consent) to try the beta version. The offer is being distributed in several countries around the world to test tuning in different climatic conditions, with different fuel quality. If, after a certain time and mileage have passed, no problems are detected on these cars, the firmware appears in the public domain.
Noise level
I switched to this car from the Renault Megane 2. My Renault was equipped with a 1.6-liter engine, a power of 113 horses, and the number of valves was 16.
After it, the Granta engine works like a tractor. Regardless of the car's mileage. Even the engine on the carburetor VAZ-21093 seemed quieter to me.
I specifically compared the noise level on a new Grant with a mileage of 5,000 km and on mine with a mileage of 55,000 km. As it warms up, the sound becomes quieter, but most likely you just get used to it.
But it is also worth considering that there are no hydraulic compensators, so you will have to adjust the valves. By the way, the engine in the luxury version (98 hp) also rumbles.

The cost of services is negotiated individually in each specific case.
List of manual transmission errors
Re-flashing process
The M 74 CAN module in the Lada Granta is located in front, opposite the passenger seat. To flash the firmware it must be removed. First, you should bend the trim and sound insulation of the interior and unscrew the 3 bolts. Now you need to disconnect the wires. This can be done by squeezing the clamp of the bracket; the connector will easily come out of its place. Of course, this work should be done with the negative terminal disconnected. The ECU has been removed, you can proceed to programming it.
In addition to the available adapter, program with an additional module and firmware, you will need a 12 V power supply, or even better, a battery. Next comes the most important part of the work. You need to connect the connectors of the adapter and the ECU with wires. You will need any 2 switches. With their help, + 12 V will be supplied to the required contacts when necessary. The connection is made in the following order:
- connector 1 (large);
- J1 - switch 1, switchable voltage (K15);
- B2 - switch 2, programming permission (12V);
- A4 - switch 2, programming permission (12V);
- E2 -CAN-L;
- E3 -CAN-H;
- K1 - 510 Ohm jumper on E3;
- connector 2 (small);
- G2;G3;G4 — mass;
- H1;H2 - non-switchable voltage (K30);
- F2 - switchable voltage (K15);
- D2 - K-Line.

Engine life
Under the hood in the “Norma” configuration
The question that causes the most controversy. Officials talk about a mileage of 150,000 km before major repairs; some have traveled 200 thousand km or more without problems. I have a friend who already had his engine repaired at 40 thousand km because the timing belt broke. Yes, the engine here is “plug-in” - this means that if the timing belt breaks, the pistons meet the valves and you can see the fist of friendship.
Engine resource 87 hp. 21116 according to the passport - 150,000 km!
Studying the forums, based on my own experience, I can say that it all depends on how you will operate the engine. The most banal thing: the quality of the oil (choose correctly) and engine operating modes - this is what the mileage before you need to do major repairs depends on.
Firmware for VAZ 2114
Publication date Jun 15, 2014, Categories VAZ cars |
Firmware for VAZ 2114, this issue haunts many motorists. It is believed that by cleaning the “brains” of a car, you can make it faster, more dynamic, and easier to drive.
Of course, in order to professionally reflash the standard ECU, it is recommended to contact special tuning studios, but if you are well versed in the essence of the issue and know exactly what you are going to do, you can replace the VAZ firmware on your own.
Before you start work, you need to find the necessary program that will fully match your car, and then the standard firmware of the VAZ 2114 can be replaced.
To search and select a program, you can refer to the extensive information contained on the Internet. Before reflashing the injector, make sure that this procedure is really necessary.
If any of the car systems does not work adequately, this means that operational errors are not due to a malfunction of the injector or the ECU in general.
Before replacing the firmware, be sure to make sure that the standard software of your car does not provide for disabling misfire detection.
If this option is “registered” in the standard program of the VAZ 2114 car, the need for flashing “no longer exists” automatically. Before replacing, it is necessary to accurately determine the type of standard firmware.
This is done with the help of competent diagnostics and scanmatics, the use of which will accurately reflect the system configuration of your vehicle.
Next, the firmware is replaced according to the general rules. Purchase a DF with a cover and a special pin for the camshaft. Connect the adapter and constantly focus on its readings (in real time) during operation.
Communication with the ECU should be restored, but if an error is reported when connecting to the port, you will still not be able to flash the VAZ 2114 firmware yourself. After this, download a new program (at your discretion) and modify the ECU.
For greater convenience, experts recommend that when performing this work, you generally remove the controller from the car. Upon completion of work, check the functioning of all systems: power supply, ignition, main relay, programming permission.
Tuning the multimedia system
In addition to the ESUP, you can also reflash the multimedia system. After the procedure, new functions will become available to the car enthusiast, and the system itself will be more modern. After the procedure, you can install rear view cameras, you will be able to access the Internet, and the player will read new file formats. You can install navigation.
So, you can look for problems in the mechanical part of the car for a long time and not find them. Or you can simply reflash the electronic system, and a lot will be resolved by itself.
As the sad experience of some car owners shows, not everything that comes off the assembly line is gold. In addition to the disappointing statistics of various parts with manufacturing defects, modern realities have added one more item - electronics. Electronic equipment often has imperfections that can make driving a vehicle very difficult. The main blow, as expected, is borne by the control unit. It is about the ECU and how its firmware and flashing is carried out that will be discussed.
Reviews from car owners about the 87 hp engine.
Most reviews are positive.
Mostly problems occur due to low-quality fuel and lubricants. The engine may start to stall and run intermittently (floating idle, stalls, loss of power, etc.). In this case, the “Check Engine” malfunction icon (indicator) should light up on the instrument panel.
The engine pulls well at low end; on the highway, even with a full load, there is enough power. This is especially noticeable when compared with a Ford Focus automatic: engine capacity 1.6, power 100 horsepower. Granta drives more fun, Focus “deflates” after 80 km per hour. As for Focus - personal experience, I owned just such a car.
Reviews
| № | Positive |
| 1. | Vladimir: I am satisfied with the build quality of the Lada Granta, there are no significant comments. I solve minor problems myself. The car is an economy class, so the shortcomings are quite noticeable. |
| 2. | Kirill: for a year and a half there are no special complaints about the car, I regularly go to service stations, carry out diagnostics and replacements. When purchasing consumables, I give preference to original ones and check the conformity of the products in the catalogue. |
| 3. | Vasily: I purchased a Granta with the new mechanics version 2181, I am 100% satisfied with the quality of work. For domestic transportation, this is generally a step forward, well done. There are minor faults, but they are not that significant and can be easily fixed. |
| 4. | Dmitry: In two years of active use of the car, I changed the transmission oil and filter once. The device works fine, there are no comments. |
| 5. | Alexander: during the year of active use of the car there were no problems, I did not contact unscheduled service. I fixed minor breakdowns myself, without visiting a gas station. |
| 6. | Alexander: I’m happy with the machine; there have been no major breakdowns in a year and a half of use. I believe that systematic maintenance and respect for technology are the main factors for the proper functioning of the mechanism. |
| 7. | Ivan: I’ve heard a number of negative reviews about the Grants checkpoint, but I can’t confirm it. There have been no major breakdowns in two years of use. |
| Negative | |
| 1. | Sergey: I am extremely dissatisfied with the quality of manufacturing and assembly of components for Lada Granta. For the first time, the car's oil seal dripped already 55,000 km. After 10,000 km, I replaced one of the transmission cables. |
| 2. | Vasily: Despite the promised transmission life of 180,000 km, mine drove only 65,000 km, after which I carried out maintenance at a service station. |
| 3. | Victor: Disappointed with the build quality of the car, there are many shortcomings, it’s a bit damp. Elimination requires time, effort, and money. It is better to buy Renault Logan where the quality has been checked, the breakdowns are minor. |
Production Serial installation of automatic transmissions on Lada Grant cars is a huge step forward in the domestic automobile industry. Japanese units have long been famous for their good quality, reliability and unpretentiousness.
I believe that most failures are caused by violation of the operating conditions of the technical device. Owners often save on timely maintenance and the purchase of original consumables. Inexpensive mineral oil is poured into the system, which is strictly prohibited.
Tuning the VAZ-2114 engine - boosting and flashing the ECU | VAZ lovers club
Most of all domestic cars do not have powerful engines, and the VAZ-2114 is no exception. For this reason, many car owners strive to increase its power. To fully exploit all the capabilities of a gasoline engine, you should change the cylinder volume or boost the engine. True, there are other ways to increase horsepower, which will be discussed below.
Increase in cylinder displacement
The most reliable and most proven way to improve the acceleration characteristics of all cars is considered to be changing the volume of a given part. In fact, everything is very simple here, since you only need to bore the piston, then slightly modify the intake manifold and change the crankshaft.
True, to perform such work requires special tools, equipment and knowledge. To bore the piston, high-tech equipment is needed, but before that, accurate calculations must be made and dimensions must be observed.
In the event that a part is ground down a couple of millimeters more than required, then there can be no talk of a positive result. Such machines are located in special workshops, so this method is not suitable for independent tuning of the VAZ-2114.
Advantages of ADACT
- Guaranteed security and quality of firmware. This is confirmed by certificates of compliance with the GOST R ISO 9001-2011 standard and the experience of calibrators. We have been working since 2006, all firmware has been tested and tested under many years of use.
- A certificate that confirms that you have installed the official ADACT program and not a fake one.
- Confirmed results. We have repaired the most cars in Russia and constantly receive positive feedback from customers.
- Engine life is not reduced.
- All diagnostic functions and fault codes from the manufacturer are saved. If any breakdown occurs, diagnostics will show the cause. The exception is the transition to E2. In this case, errors that appear when changing the environmental standard are removed.
- Reasonable prices. We are aimed at ordinary drivers, not sports car owners.
- Test Drive. Within 10 days you test the results and can get your money back if you don’t like something.
Results
Most Grant owners switched to them from previous AvtoVAZ products. Granta, Priora and Kalina are almost identical cars, the only difference is “in the filling”, and the ancestors of these engines were installed on the VAZ-2108.
By modern standards, the engines are reliable and should not cause trouble to their owners.
At the end of last week, we visited a completely fresh Lada Granta, which we did chip tuning. Engine 1.6 with 8 valves and 87 hp. The exhaust system was replaced with a kit from the Stinger, so Euro-2 firmware was required with modified fuel supply schedules, OZ, etc.
Lada Granta cars were equipped with M74 units with K-line or CAN interfaces. We will program this unit by removing it from the car and connecting it on the table. What’s noteworthy is that the unit has a CAN bus, but “wanted” to be programmed only via K-Line.
For work we will use the original J2534 Openport 2.0 adapter, a universal Combiloader cable and a bootloader from the same manufacturer.
Characteristics of automatic transmission
The idea to install an automatic transmission on the Lada came to AvtoVAZ in 2010, but was implemented only in 2011. A long-term contract was signed with the Japanese company Jatco, known for the quality of its variators and hydraulics.
The box is not the best in terms of technical parameters, but it has been tested on other models for several years. It is safe to say that all weak points are known, as well as ways to eliminate them.
Between 2006 and 2010, Jatco was installed on Nissan Note cars. Numerous reviews from owners speak positively about the results of operating the unit.
Installation of the machine was complex, as specialists had to make more than 30 settings and adjustments. They say that Austrian craftsmen took part in the calibration.
Excellent ergonomics of the box. The handle (curtain) is of optimal height and fits comfortably in the hand. In the selective part there are icons for viewing. The mode is duplicated directly on the dashboard.
At the same time, fixing the lever in one position is questionable. Different operating modes of the machine are possible:
- fixed first and second gear;
- a mechanical button to disable the “overdrive” option - prohibiting the transition to fourth speed.
You can “forget about going into third gear” if the oil has not warmed up above 15°C. Fourth is activated at 60°C.
It is important to know. The design of the power plant does not include a flywheel, but a drive disk.
Due to the transmission housing, the body height has decreased by 1.5 cm. The automatic transmission control unit is located on the left front side, behind the optics. Many car owners are not happy with this, since in a head-on collision the risk of damage to the module is 100%.
The operating modes of the car are configured for driving in the city, on the highway, outside the city, and to a lesser extent, the box is adaptive for driving on country roads. The noise level is minimal.
How does the electronic unit on Grant work?
Before making changes to the car's firmware or performing diagnostics, you need to consider the basic principles. As much as some would like to jump right into making practical changes, you need to understand how the electronic “brain” works.
Any computing system, be it an ECU or a home PC, is a storage device. A home PC contains photos, videos, games, and work software. The computer constantly stores the user’s actions, errors, and data about software failures. All this is hidden among system files hidden from view.
The Lada Granta electronic control unit is also a computer, only the tasks it is designed to solve are more specific. There is also diagnostic information here. It is stored in RAM. This memory stores all the data that comes from various sensors. Information is stored until the block calculates everything it needs for some actions, then the information is erased from memory.
When it comes to diagnostic information, the car owner must be very careful. RAM cannot operate without a power source.
The control unit is a mini computer with specialized functionality
However, in addition to the RAM, there are other memory blocks of the controller. They are completely independent of nutrition. The data stored in them is unchanged. Unchangeable until new firmware is updated. These are PROM and ERPZU.
The first chip stores all the firmware data that was made at the factory. All the original algorithms and operation schemes of all nodes are embedded here. All diagnostic information, calibration data, vehicle weight, engine power and other Grant parameters are also stored here.
The second chip stores anti-theft information. Here are the codes that are on the alarm keys. If the codes do not match, then Grant will not go.
Tuning the Grant chassis
The Lada in its new guise has acquired a soft suspension system, which was created, in particular, for people who love a comfortable ride, and this really becomes noticeable in comparison with previous models. Any tuning of the chassis and suspension can make the ride more rigid, which improves handling, but at the same time the margin of comfort is lost. Changes can be made better on your own by reducing the coils of springs on the rear suspension of the car. There is no point in buying new springs, since they will lead to the suspension becoming stiff and uncomfortable. To provide a little stiffness, the springs are cut equal to one turn on the two rear springs. Stretching struts, which can also be installed on the front struts, can stretch the body a little, while giving torsional rigidity to the body. On sharp turns, such a change can give easy control at high speed, without tilting the body to one side. The strut extensions can be borrowed from the Lada Kalina model. In addition to the standard settings of the chassis, the levers, suspension and shock absorbers can be changed, which at the very beginning, even before rollback, are replaced with a similar option for the Lada Granta. To lower a car's suspension, you can use several methods.
