Can a Small Car Pass the Annual Inspection After Installing a Rear Spoiler?
2 Answers
Small cars cannot pass the annual inspection after installing a rear spoiler. Below is more information about car modifications: Legal Modification Scope: Modifications can be made to the body color (including interior), engine, fuel type, and chassis number. Changes to the body, chassis, or engine are only permitted if they are damaged beyond repair or have quality issues. When applying for modifications, proof from a repair shop and documentation of the origin of the replaced engine, body, or chassis must be provided. Illegal Modification Scope: Illegal vehicle modifications refer to alterations to the vehicle's appearance, power system, transmission system, or braking system that exceed the original design load capacity and functionality, as well as replacing key components, without legal approval or manufacturer consent. Car modifications have certain limitations, and random modifications may fail the annual inspection. Therefore, modifications must comply with relevant regulations.
I often get asked whether adding a spoiler to a sedan can pass the annual vehicle inspection. According to domestic regulations, installing a spoiler is considered a modification of the vehicle's appearance and must be registered with the vehicle management office. However, the actual process is particularly cumbersome. Unless it's a high-performance model that comes with a factory-installed spoiler, it's very difficult for ordinary family cars to get approval. During the annual inspection, they strictly check if the vehicle's appearance matches the photo on the registration certificate. Obvious modifications like spoilers are immediately flagged. I know a few car enthusiasts who modified their vehicles, and they all ran into trouble—either they had to remove the spoiler on the spot or they couldn't pass the inspection. So, I sincerely advise against the hassle. Adding a spoiler to a family car doesn't actually improve performance much and might even increase wind resistance and fuel consumption, which isn't worth it.
