Can Car Body Kit Modifications Pass the Annual Inspection?
2 Answers
After modifying the vehicle, promptly submit it for approval to the traffic administrative department. Once approved, the modified vehicle can pass the annual inspection in the following year. Below is relevant information about body kit modifications: 1. Introduction: Body kit modifications refer to reducing the reverse airflow generated during car driving while increasing the downforce of the vehicle. This makes the car more stable during driving, thereby reducing fuel consumption. 2. Cases that can pass the annual inspection: Modified cars with manufacturer-released body kits, side steps, or color changes are legal. Before dealers release modification kits, manufacturers have already submitted the modified vehicle information to the vehicle management office. When registering the vehicle, the office will compare the information provided by the manufacturer. However, if the owner privately requests the dealer to change the vehicle color before registration, it will definitely not work during the registration process. The reason is the same—the vehicle management office will compare the information based on the manufacturer's provided data.
Last year, I modified the front and rear bumpers of my car, originally intending to make it look cooler, but it almost failed the annual inspection. The inspector said the bumper dimensions exceeded the factory standards and required me to remove and reinstall them to pass. Later, I checked the regulations—China’s annual inspection standards are quite strict. If the bumpers are modified too drastically, altering the original dimensions or affecting safety (e.g., widening the bumper and increasing braking distance), you must register the changes with the vehicle management office; otherwise, it will definitely fail. Routine inspection items include checking for exterior and chassis height modifications. So, if you really want to modify your car, I recommend choosing compliant designs, consulting professional shops in advance, or taking photos as evidence to avoid wasting effort like I did and having to make corrections. Safety comes first—don’t risk it just for looks.
