Does Adding a Rear Spoiler Require Registration?

[LaAaliyah]

Adding a rear spoiler requires registration as it is considered a modification to the vehicle's exterior. If the spoiler is installed without proper registration, the traffic police department may impound the vehicle, confiscate the illegal modification, order restoration to the original condition, and impose penalties in accordance with the law. After the modification is completed, the vehicle's registration certificate must be updated with a new photo to reflect the changes, ensuring the vehicle can pass annual inspections and routine safety checks. The key requirement for installing a rear spoiler is that it must not exceed the overall dimensions of the vehicle. Rear spoilers are part of aerodynamic design, helping to increase downforce during high-speed driving, thereby improving stability. Additionally, a well-designed spoiler can reduce air resistance, contributing to better fuel efficiency to some extent.
