一. Legality considerations

      The legality of car modification mainly depends on the laws and regulations of the country and region. Restrictions on car modification vary in different regions, but they usually involve regulations on vehicle appearance, power system, chassis suspension, etc.

1. Appearance modification:

       Body color: After changing the body color, the car owner needs to go to the vehicle management office to go through the change procedures within the specified time (such as within 10 days) and update the driving license photo. Certain specific colors such as fire red, administrative law enforcement color and engineering emergency yellow are usually not allowed to be modified.

       Bumper and wheels: Bumper modification cannot change the overall length and width of the vehicle to ensure that safety is not affected. The size of the wheel cannot be changed, but replacement of the same size is allowed.

      Other appearance components: For components that may affect aerodynamics and driving stability, such as surrounds, tail wings, etc., you need to choose a kit that conforms to the vehicle design, and ensure that it is installed firmly and does not affect the line of sight and lights.

2. Power system modification:

      Engine: Under normal circumstances, the engine is not allowed to be replaced. However, if the engine is damaged or has quality problems, the car owner can apply for a change with a certificate from a regular repair shop and a certificate from the source of the replacement engine. The engine model is not allowed to be changed.

      Intake and exhaust systems: It is often illegal to add turbocharging without permission, modify the intake and exhaust systems, and other actions that greatly improve power performance. In addition, if the noise of the modified exhaust system exceeds the legal standard, it may also be regarded as illegal modification.

3.Chassis suspension modification:

      Chassis suspension modifications need to be treated with caution and are generally suitable for car owners who have higher requirements for vehicle performance. Reasonable chassis modifications can improve handling performance and pass annual inspections. Suspension modifications include adjustments to shock absorbers, suspension structure rods and body rigidity. The selection of shock absorbers is particularly critical, as it directly affects the comfort and handling stability of the vehicle.

4. Interior modification:

      Interior modifications are allowed as long as they do not affect safe driving, but the removal and installation of seats must comply with the regulations of the Vehicle Administration, and the vehicle structure cannot be changed without authorization. Audio modification is one of the common interior modification projects, and it is usually allowed as long as it does not affect the overall function of the vehicle.

二. Security considerations

      Unreasonable modifications may bring hidden dangers to the driving safety of the vehicle.

1. Choose reliable modification accessories:

      Car owners should choose well-known brands and certified products. They can check reviews, consult professionals or refer to the experience of other car owners to ensure the quality and safety of modified accessories.

2. Find a qualified and experienced modification shop or technician:

      The modification process should be professionally installed and debugged by qualified and experienced modification shops or technicians. Different types of modifications have different potential risks and precautions. Professional technicians can ensure the safety and effectiveness of the modification process.

3. Pay attention to the performance of the modified vehicle:

       Modified vehicles should undergo comprehensive inspection and testing, including testing of braking, suspension and other performance. If problems are found, adjustments and repairs should be made in time to ensure the safety performance of the vehicle.

4. Follow the manufacturer’s guidelines and original vehicle safety structure:

      When modifying the interior, such as seats, speakers, etc., the manufacturer's guidelines should be followed and the safety structure of the original car should not be damaged. Choose appropriate electrical equipment to avoid affecting airbag deployment and circuit safety.

5. Pay attention to maintenance after modification:

       Modified vehicles may require more frequent maintenance. For example, after a high-performance brake system is modified, the brake pads will need to be inspected and replaced more frequently. Car owners should understand the maintenance requirements after modification and follow relevant regulations for maintenance.
