Whether installing a spoiler on a sedan is illegal depends on the specific circumstances: 1. If the spoiler is small and only serves as a decorative accessory, it is legal; 2. If the installed spoiler is exaggerated, it needs to be registered with the vehicle management office, otherwise, it is illegal. According to the motor vehicle registration regulations, altering the body color, replacing the engine, body, or frame without completing the registration change within the specified time limit will result in a warning or fine from the traffic management department of the public security authority. According to the motor vehicle registration regulations, if a registered motor vehicle falls under any of the following circumstances, the owner must apply for a registration change with the local vehicle management office: 1. Changing the body color; 2. Replacing the engine; 3. Replacing the body or frame.
Regarding whether installing a rear wing on a sedan is illegal, based on personal experience, it's quite common. I've seen many friends add rear wings to their beloved cars, mainly for the cool factor and to give it a sports car vibe. But honestly, installing one illegally could be against the law. In China, vehicle modifications are strictly regulated. According to the GB7258 vehicle safety standards, if a rear wing alters the vehicle's height or affects the drag coefficient, it's considered an unauthorized modification. In case of an accident, traffic police can impound the vehicle, impose fines, and even deduct points in severe cases, with repair costs not covered by insurance. I once encountered a case where a colleague's car failed its annual inspection due to a flashy rear wing and had to be removed and reinstalled. For safety, it's best to first apply for approval at the vehicle management office and undergo testing. When choosing a rear wing, consider lightweight materials and avoid blindly opting for large sizes, as this can compromise stability. The whole process isn't too troublesome—just spend some time consulting professionals to get it done right.
