Is it legal to buy a new car and want to modify it, and what else do you need to go after legally in

For car modification, the state has stipulated the legality of the modification of different parts of the car, and the main ones that can be legally modified under the existing laws and regulations are:

1. Install a rear wing.

This modification does not change the appearance of the vehicle on a large scale, nor does it affect the safety of the vehicle, and does not disrupt the balance of the nature of the vehicle leaving the factory. **The cool rear wing still has a full feeling of pulling wind.

2. Modify the front bumper.

Replacing the front bumper is a change in the shape of the car, which is feasible after approval. However, it can't be changed too much, after all, it still needs to be approved, and too much exaggeration may lead to manual approval.

3. Vehicle color.

To change the color of the vehicle, you only need to notify the approval, so if you don't like the current color, you can declare the change yourself. However, there are three colors that belong to the special colors of special vehicles and cannot be used. Red is for fire fighting, yellow is for engineering rescue, and white is for national administrative law enforcement.

4. The frame number can be changed, but the frame model cannot be changed.

The frame can only be replaced if the vehicle has been damaged beyond repair or if there is a quality problem. When the frame is replaced, the frame number naturally changes. However, the frame model cannot be changed, otherwise it is no different from changing a car.

5. Interior. In principle, it can be modified without affecting safe driving. However, the seat cannot be removed, the structure of the vehicle cannot be changed, and the structural characteristics of the vehicle registered with the DMV cannot be changed without authorization.

6. It is allowed for the engine to rotate, but the model of the engine cannot be changed.

Engine changes can only be made if they are damaged beyond repair or if there are quality problems. When applying for a change, a certificate from the repair shop and a certificate of origin for the replacement engine must be issued at the same time. It is best not to replace the vehicle with a wind-pulling engine, otherwise the relevant departments have the right to detain the car, and in serious cases, it can even be forced to scrap.

7. If you want to change to a dual-fuel model, you need to modify it in a legal modification plant and apply for a change in fuel type at the same time - it should be noted that the vehicle management department in some regions does not support this business change, and you need to consult in advance.

Modifications are prohibited:

1. Raise the chassis.

2. The tire size cannot be arbitrarily widened or changed to a very exaggerated appearance.

3. Modification of intake system and exhaust system.

It is certainly not possible to modify the exhaust system to be like a rocket, and it is not possible to change the unilateral exhaust to a bilateral exhaust, in short, most of the modifications that affect the basic layout and parameters of the vehicle are not allowed.

In addition to these, the others are not expressly prohibited or allowed, depending on the specific situation in various places, such as light modification, theoretically, the user can also modify the lights of the vehicle, but must meet the intensity, color temperature, beam irradiation optical axis and offset and other aspects of the safety technical testing conditions, it is obviously not feasible to do a set of headlights at will.

Modification definitely needs to be filed with the DMV.

Interior modification of the car. As long as it does not affect the safety of driving on the road, it can be modified, but it must be remembered that the airbag must not be affected in the process of modification, which is a very important point.

Powertrain modifications. The main modification is to increase the power output of the car. When modifying, you must pay attention not to damage the engine because of a momentary pleasure, and cause serious safety accidents.

The bumper of the predecessor of the car, to a certain extent, is allowed to modify the bumper, as long as it is not the kind of modification that is too excessive, the traffic police will not care much.

1) Changing the color of the body;

b) replacement of the engine;

3) Replacing the body or frame;

If the car is modified, such as the body modification and the wheels, the size does not change, but the shape is changed, and the surrounding, etc. can be recorded!

In fact, in a sense, this is to improve the driving safety of the owner, and use Bluetooth to answer ** when driving, this kind of modification that is conducive to safety, the traffic police also raise their hands in agreement.

The appearance of the car occupies a very important position, generally including stickers, body painting, car logos, front and rear bars, large surrounds, high rear wings, open engine covers, window side weather shields, HID xenon headlights, headlight decorative panels, front and rear lenses, lowered body and so on. The quickest and easiest way to change the body is to add an aerodynamic package. Adding an aerodynamic package doesn't make the car go faster, strictly speaking, a good aerodynamic package usually slows down the car and makes the car more consistent.

Car modification general modified parts:

1. Brake system: There are many ways to upgrade the brake system, such as replacing the enlarged brake disc and multi-piston brake calipers and high-performance, high-temperature resistant brake pads, you can also replace the brake oil with a higher grade, or replace the high-pressure brake hose made of metal.

2. Suspension system: The modification of the suspension system can be roughly divided into replacing shock absorbers, strengthening suspension structure rods, and installing balance bars. One of the most influential and most heavily modified projects is the shock absorber.

3. Air intake system: The air filter on the engine is to filter the air required for the operation of the engine, and this device is available on the gasoline engine.

4. Engine power: The engine is to the car as the heart is to the person, and the most important part of the whole car is here.

5. Exhaust system: The exhaust gas will be discharged after the engine is done, and the quality of the exhaust efficiency is directly related to the quality of the engine efficiency.

6. Oil supply system: It can be divided into two categories: hardware and software, and the purpose of hardware is to improve the oil supply per unit time.

Color change: It has been illegal to change the color of the car for many years in the past, but as China has gradually become a big car country, the car culture is getting thicker and heavier, and many car friends like more personalized appearance and color, so today's policies and regulations have been relaxed to a certain extent, and the seat can not be changed at will, although usually no one checks but is actually not allowed, whether it is to change the number or change the function (change the sports seat) is not allowed.

Wheels: the same can be modified, but the car can not change the sports class large one-inch wheels, this kind of annual review is not passed, brake calipers can also be changed, usually see a lot of modified cars on the road, now the domestic traffic police management is relatively relaxed. It is also legal to retrofit roof racks, entrance and exit treads, replace radiator masks and/or bumpers, and change wheels.

However, there are also prerequisites for these. First of all, we can modify the body color, engine, fuel type, frame number, etc. Of course, the modification referred to here is not to change as you want, but to have clear regulations.

In fact, both the exterior and interior can be modified, and the interior can be changed as you like, as long as the seat structure and layout are not changed; Because the inside is only felt by the driver and passengers, and it will not cause trouble to other vehicles and pedestrians. After getting a new car, some car owners may pay more attention to the safety of the car, and feel that the front and rear bumpers of the original car are not strong enough, so they go to do bumper modification, which is no problem, and the annual review can be passed.

If the light is modified, if it is a halogen upgrade xenon, as long as the color temperature is in the range of 4300K-6000K, it can be modified. However, some areas are more strict and may not allow modifications. Engine Modification:

Air intake system, exhaust system, fuel supply system, crankshaft linkage mechanism, valve mechanism, compression ratio, booster system, etc. If the car changes color and replaces the engine, body or frame, the car must be submitted for inspection, and the motor vehicle safety and technical inspection certificate must be submitted if the engine, body or frame is replaced.

There are three main aspects of legal modification of vehicles, one is to install a rear wing, as long as the height and width are not violated, it is completely allowed; The second is the vehicle painting, as long as the color of special vehicles and administrative law enforcement vehicles is not used, the application for approval can be passed; The third is to change the interior, which can be modified without changing the vehicle structure and without affecting the safe driving.

The style of the hub can be changed, as long as the size of the hub is consistent with the registration certificate; Luggage racks and side footrests can be installed, and the height of the additional luggage racks must be controlled within 300 mm; The color of the body can be changed, and you must register and change the vehicle information at the vehicle management office within 10 days; The grille and front and rear bumpers can also be changed.

It is possible to modify the body color, interior, audio, headlights, bumpers, etc. The body, frame, and engine can be modified, but only if it has been damaged beyond repair or has quality problems.

Vehicle modifications are legal and need to be applied to the traffic management department. Modifications to vehicles can only be carried out within the scope of reasonable modifications. It is illegal to modify a vehicle if it is beyond the scope of modification.

Any vehicle modifications should be applied to the traffic management department. According to the provisions of the "Road Traffic Safety Law", without the permission of the public security traffic management department, it is illegal to modify the chassis, engine, suspension, transmission system, steering system, tire hub, lights, body color spraying, appearance structure, modification and upgrading of the body appearance or power system without the permission of the public security traffic management department.

After the car is modified, you need to go to the local traffic management office to replace the driving license**. If it is not replaced in time, the traffic police will penalize, and the modification will also affect the annual inspection of the car. Car modification is also easy to cause traffic accidents, there are certain safety hazards, and it is not recommended to modify the car.

The car modification part is legal, as is the car interior. For example, if you add some car pendants and the like, the car audio can also be modified, and the car steering wheel and gear lever can also be replaced. Except for these devices, which can be modified at will, the others cannot be modified at will.
