How to Modify a Car Legally?
2 Answers
In principle, modifications are allowed as long as they do not affect safe driving. However, seats cannot be removed, and the internal structure of the vehicle cannot be altered. If you need to change the body color, replace the engine, or replace the body or frame, you can directly apply for a modification registration at the vehicle management office within ten days after the change.
To make a modified car legal, I believe the key is to comply with traffic regulations and vehicle registration rules. I enjoy making minor modifications to my car, but I always check what can be altered beforehand. The body color can be changed, but it must be registered with the vehicle management office, and the color shouldn’t be too flashy or affect identification. Wheel rim sizes should stay within the original manufacturer’s standards—going too large can increase the risk of skidding and accidents. I’ve also modified the lighting, but brightness and color must meet national standards—not too bright or dazzling. For performance, avoid tampering with the engine and exhaust system. If modifications are made, always use certified parts to ensure emissions compliance for annual inspections. Safety is the bottom line—don’t recklessly adjust brakes or suspension to avoid accidents. I recommend checking official guidelines or consulting professional shops before modifying—they know the regulations. Once everything is registered, driving becomes worry-free and cost-effective.
