How big is the hole in the car's brain when it is modified like this?

The parts that are generally changed in automobile refitting:

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 and high-temperature resistant brake pads, and replacing them with higher-grade brake oil or high-pressure brake tubing made of metal.

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

3. air intake system: the air filter on the engine is used to filter the air required by the engine operation, and this device is installed on gasoline engines.

4. engine power: the engine is to the car what the heart is to people, and this is the most important part of the whole car.

5. exhaust system: the engine will exhaust exhaust gas after doing work, and the exhaust efficiency is directly related to the engine efficiency.

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

car body modification:

1. Car lights

generally refer to upgrading lighting, upgrading xenon lamps or LED lamps for the halogen lamps of the original car, installing fog lamps for vehicles with simple fog lamps, and interior lighting. These practical situations are all allowed.

2. Decorations

such as car stickers and color-changing films are legal as long as they are not more than 3% of the body area, which can meet the persistent and personalized mentality of some car owners.

3. Front and rear bumpers

Bumpers are allowed to be installed in small passenger cars, such as plastic decorative bars that are rare in SUVs and competitive bars that are rare in off-road vehicles.

4. It doesn't matter if the wings and tailpipes are modified. Generally, everyone tells us that they are fake, but they are just for decoration. It doesn't matter if the tail throat is installed, but it is not recommended to install the tail if it is a front-driven car. It will be a joke to reduce the downward pressure on the tail before driving.

5. Roof rack and suitcase

This is also allowed, as long as the height is not more than 5 cm from the roof, and the luggage rack should be careful not to exceed the height when loading goods.
