Is It Illegal to Install a Rear Wing on a Car?
2 Answers
Installing a rear wing on a car is illegal. The main reasons are: 1. Adding a rear wing to a car is considered illegal modification. 2. Traffic police authorities state that modifications such as altering tires and rims, adding rear wings, lights, and exhaust pipes are all illegal modifications. The vehicle must be restored to its original condition to pass inspection. Additional Information: 1. If you wish to change the vehicle's color, replace the engine, or alter the body or frame, you must first make the changes and then submit an application for modification registration at the vehicle management office within 10 days. However, regulations prohibit simultaneously replacing the engine and frame, and the vehicle registration information on the driving license must be updated promptly. 2. Rear wings that have not been professionally adjusted or designed can not only pose safety hazards but may also prevent the vehicle from passing inspection. Any car modifications must comply with relevant regulations.
Adding a rear spoiler to your car might be against regulations, depending on how you do it. According to China's traffic laws, any modifications to a vehicle's exterior must be registered and approved by the vehicle management office—unauthorized changes are prohibited. While a spoiler can enhance the car's appearance or improve high-speed stability, installing one without approval constitutes illegal modification. With decades of driving experience, I've seen many friends add spoilers for novelty, only to be pulled over by traffic police, fined, or ordered to revert the changes. Safety is also a concern: poorly designed spoilers can affect the vehicle's center of gravity, increasing the risk of losing control, especially on slippery roads. I recommend consulting a professional repair shop or the vehicle management office first to ensure compliance with national standards. Don’t overlook these details for the sake of style—safety should always come first in daily driving, and the risk of violating regulations isn’t worth taking.
