With the increasing trend of car refitting, car owners are often inseparable from the topic of "how to refit cars". In the era of "cars have commonness, modification shows individuality", modification is almost the only way to pursue distinctive gameplay. So what is car modification? Which modifications are legal? What modification violations?


With the continuous improvement of living standards, cars are no longer an unattainable luxury. When I first bought the car, many car owners always found many unsatisfied things, such as the same appearance, poor driving power, the engine burning too much oil, the car turning unsteadily... These kinds of dissatisfaction are more or less bothering the car owner, they are not very important, but they always feel the same.


Automobile refitting can just solve such dissatisfaction, which is, of course, a common reason for automobile refitting. What is the underlying reason? Before doing so, let's first understand what is "car modification".


What is car modification?


As we all know, there are many types of cars, such as sedan, MPV, SUV, off-road four-wheel drive, etc., These are purchased and used by ordinary families, so the current popular car modifications are mainly concentrated on these types of cars.

According to the driving purpose of the modified vehicle, it can be roughly divided into two directions:


High speed modification


All the above types of vehicles can be used, mainly to improve the acceleration ability, maximum speed and handling at high speed. In short, the car is "fast".

Manyueye modification

Basically, SUV and off-road four-wheel drive are the main vehicles. The purpose is to have a stronger passing capacity than the original vehicle after refitting, that is, people often say "it can climb more".


According to the specific component classification of the modified vehicle, it can be divided into:

Dynamic modification

Including engine mechanical and electronic modification, gearbox modification, etc.


Chassis suspension improvement

Including chassis strengthening, suspension improvement, tire hub, brake modification, etc.

Appearance modification

Perimeter, sticker, body painting, etc.

Interior decoration


Replace leather seats, steering wheel, gear lever, etc.

Modification of electronic products


Various testing instruments, adjusting electronic products, audio multimedia modification, etc.


The above classification is simple. In fact, in the specific project of automobile modification, the project may involve two aspects, such as the replacement of wheel hubs and tires. This is not only the modification of chassis and suspension, but also the modification of appearance.


Why should a good car be refitted?


All car manufacturers claim that their cars are the best, because their efforts for each product are quite amazing. However, considering many practical market factors, their products are often a comprehensive balance of cost, price and quality, which means that each car has its own golden mean.


Which modifications are legal and which are illegal?


Appearance chapter

Automobile refitting


Conventional car paint can be modified first, but it cannot be changed into police cars, fire engines and other government vehicles. Is it legal to paint cars? Of course, after the modification is completed, it needs to register with the vehicle management office within 3 days, otherwise it will be treated as illegal modification. It is not allowed to change the color of the film, because this will prevent the film from escaping after the accident and increase the difficulty of law enforcement. In addition, it is strictly prohibited to modify the logo.



Replace the shock absorber, wheel hub and brake caliper.




It has become normal to refit automobile shock absorbers, wheel hubs and brake calipers. Is it legal or illegal to replace the shock absorber, wheel hub and brake caliper? In terms of laws and regulations, the above three types are illegal modifications. Although the daily traffic police can hardly find the car, after an accident, the modified car will inevitably become the main accident undertaker, which may lead to the insurance company refusing to compensate or underpaying compensation, so we should think twice about these modifications.


Improved tail

What's the function of the tail? The tail wing makes the car look more three-dimensional. In addition, when the car is running at high speed, the tail wing can also provide downward pressure, making the car more stable at high speed. Therefore, the installation of tail fins has become one of the interests of some car owners, but strictly speaking, the installation of tail fins also belongs to the scope of illegal modification. Whether to deduct points depends on the severity of local urban law enforcement.



Indoor supplies

Legally changing "interior decoration" and illegally changing "structure"



The most free part of car modification is the interior part, which can be modified "at will", such as installing seat covers, adding sun visors, etc. But you can't change the internal structure of a car. For example, a passenger car can't be changed into a truck illegally, and a five seat car can't be changed into a seven seat car.


Power chapter

Change engine power parameters


The performance parameters of the engine cannot be changed, otherwise it is illegal to modify. Moreover, the tolerance of the traffic control department on the parameters of the modified engine is lower than that of the modified wheel hub and brake caliper. In addition, the exhaust cannot be modified without authorization. Under the current annual review system, the above modifications cannot pass the annual review, and it is recommended that players operate legally and legally.


To sum up, we only need to remember the modified power parameters. The car structure is illegally modified, and the interior is legally modified. The modified paint needs to be registered in the vehicle management office, otherwise it is illegal to modify. If we grasp this principle, there will be no major problems in the modification.
