Modifying a vehicle's front lip and rear bumper can be registered. Requirements for modifications: Strictly speaking, installing side skirts and front lips currently falls under illegal modifications. Therefore, even if you proactively go to the vehicle management office to register after modification, they will only ask you to restore the vehicle to its original state. Thus, it is not recommended to privately install front lips and side skirts. Currently, legal modifications mainly include tires of the same specifications as the original factory, roof racks under 300mm, interior modifications that do not alter the vehicle's original structure, body color changes, side steps, grilles, and brake systems. Impact of these modifications: First, after installing a front lip, the vehicle's ground clearance will significantly decrease, making it very easy to scrape off the entire bumper when entering underground garages—just imagine the repair costs. Secondly, encountering traffic police on the road will become nerve-wracking, as you might be invited for a "coffee chat." Lastly, during the annual inspection, you will need to remove and restore the modifications, undoubtedly wasting a considerable amount of time and money.

I'm obsessed with car modifications, adding front splitters and rear skirts to make my ride stand out! Last year, I installed a carbon fiber front splitter that didn't exceed size limits, so I successfully got it registered. Just filled out forms and took photos at the DMV, got it done in 2-3 days. The registration process is simple, as long as the modifications aren't too extreme—like keeping the height under 5cm to ensure safety. If you don't register modifications, you risk a 200-yuan fine if caught on the road, and it could affect your annual inspection. I recommend checking local regulations or consulting a professional tuning shop before making changes to avoid wasting money. Modding is a great way to express individuality, but it's crucial to stay within legal limits for peace of mind—don't risk your annual inspection for temporary thrills.

As a seasoned driver with 20 years of experience, I'm well aware of the risks of car modifications. Front splitters and rear bumpers can be registered, but the size regulations are strict, and the failure rate for registration is high if the modifications are too extensive. I've seen a neighbor get fined after modifying their car, which also affected their insurance claim. Before registering, measure the differences in length and height carefully, and avoid using low-quality materials. Safety comes first—consult the vehicle management office or a car repair shop beforehand. If you must proceed, choose certified products to minimize trouble. This way, you can enjoy car modifications without unnecessary hassles.

In the shop, we often assist car owners with registering modified parts. The dimensions of front splitters and rear bumpers must comply with regulations, ensuring length, width, and height do not exceed 10% of the original vehicle's specifications, and non-flammable materials should be used. For registration, bring the vehicle's documents and invoices for on-site inspection at the DMV; approval leads to registration. Sometimes, issues arise at the connection points—if loose, reinstallation is necessary. After modifications, always test stability before hitting the road. Handling this affordably isn't difficult.
