Is Filing Required for Installing a Front Splitter?
2 Answers
Installing a front splitter requires filing. The following modifications to a car require filing: Installing a full body kit: Installing a full body kit is a very clear item in car appearance modifications. Before modification, it is necessary to inquire with the vehicle management office whether it can be modified and to file for registration. Installing front and rear spoilers: Spoilers, also called diffusers, can increase downforce during car driving. However, most spoilers on cars are basically decorative, similar to front splitters. Installing a rear wing: From the installation method, rear wings include adhesive-mounted and drilled-fixed types. Their function is also to increase downforce during high-speed driving. Generally speaking, installing a small rear wing is decorative and can be directly installed, while installing a large rear wing requires filing for registration with the vehicle management office.
When I modified my car before and added a front splitter, whether it needs to be registered really depends on local regulations. For example, in China, modifications to the vehicle's appearance like a front splitter, which may alter the height or aerodynamics, require registration at the vehicle management office. Otherwise, it won't pass the annual inspection. I once experienced not registering it, got stuck during the annual inspection, and spent several days removing and reinstalling it, which was incredibly frustrating. The registration process is simple—just bring your ID and vehicle license to the counter, costing a few hundred yuan, mainly for peace of mind. Don’t underestimate this; if you’re stopped by traffic police on the road, you might face fines or be required to restore the original condition. It’s advisable to check local traffic regulations before installation, as rules vary significantly by city—don’t take the risk.
