What are the regulations for car modifications?

Modifications to body color, engine, fuel type, and chassis number are permitted. Replacing the front bumper, which alters the vehicle's appearance, is allowed after approval. Modifications such as widening tires, intake systems, and exhaust systems are not permitted.
As a car enthusiast who frequently modifies vehicles, I believe the core principle of car modification regulations is safety first. In China, modifications must avoid prohibited areas - for example, engine displacement cannot be increased, and exhaust systems cannot be converted to loud straight pipes, otherwise you'll face fines for noise violations. Headlights can't be arbitrarily brightened and must meet standards to prevent glare. Changing body color requires registration with the DMV, otherwise you'll fail annual inspections and receive penalty points. Lowering or raising the chassis should be moderate, as excessive changes affect handling and increase rollover risk. Some enthusiasts like modifying suspension systems, but must ensure overall vehicle stability - don't take risks just for looks. Regulations vary by region - some cities strictly control body decals, while Beijing/Shanghai/Guangzhou focus more on emission standards. I recommend checking laws and consulting professional shops before modifying to avoid regrets later, as insurance may deny claims for accidents involving illegal modifications. Safe driving outweighs everything - only legal modifications let you drive with peace of mind.
