Is it illegal to install a rear wing on a car?
2 Answers
Installing a rear wing on a car is not illegal. Here is more information about car rear wings: 1. Introduction: A car rear wing refers to the ducktail-like protrusion installed at the rear end of the car's trunk lid. It is part of the car's aerodynamic kit and primarily serves to reduce the lift force at the rear of the vehicle. 2. Precautions: When modifying the rear wing, the car owner must file a record with the vehicle management office in advance. After the modification is completed, they must also take new photos and update the photo on the vehicle registration certificate. 3. Function: It can effectively reduce the air resistance generated when the car is driving at high speed, offset part of the lift force, control the car's tendency to float, reduce the impact of wind resistance, improve driving stability, and make the car's appearance more aesthetically pleasing.
I've pondered this issue while modifying my own car. Adding a rear spoiler isn't directly illegal, but it depends on how it's installed. China's Road Traffic Safety Law requires modifications to comply with national standards, otherwise fines and penalty points may apply. I've seen a friend install an oversized spoiler and get stopped by traffic police who fined him 200 yuan for illegal modification. The key factors are size and safety: if the spoiler is too high or unstable, the car may roll over or lose control at high speeds, endangering both the driver and others. So it's essential to choose compliant products and avoid exaggerated styles. Additionally, remember to file the modification - I personally went to the DMV to apply for documentation, which took quite some effort. Unregistered modified vehicles risk insurance claim rejection in case of accidents, leading to significant losses. I recommend first visiting a professional shop for vehicle measurement and proper selection - safety is more important than appearance.
