Which Type of Spoiler Does Not Affect Annual Inspection?

Regardless of the type of vehicle spoiler being modified, it will not pass the annual inspection. If you wish to modify your vehicle without affecting its normal annual inspection, you must complete the registration process with the vehicle management office after installing the spoiler. Once the registration is completed, the vehicle can undergo the annual inspection normally. 1. Methods for Failing Motor Vehicle Inspection: If the vehicle fails the inspection, it must be repaired based on the reasons provided by the inspection station. The vehicle must then be re-inspected within the specified time frame. After failing the inspection, there are three opportunities for re-inspection. Exceeding three re-inspections or the re-inspection deadline will require paying the annual inspection fee again. 2. Points to Note for Vehicle Annual Inspection: Ensure all traffic violations and unresolved traffic accidents involving the vehicle are addressed. The vehicle's exterior must remain intact, with no more than 30% of the body color modified. The vehicle's lights must function properly, and all related features should be in good working condition. Additionally, the vehicle must have a valid compulsory traffic insurance policy for the current year.

As someone who frequently researches car modifications, I believe the key to choosing a spoiler is not exceeding standard dimensions. According to China's annual inspection regulations, any additions to the rear of the car must not be too tall, too wide, or obstruct the rear view. Generally, the small ducktail spoiler that comes with the factory is the safest option—it just slightly raises the edge, doesn't affect the vehicle's overall profile, and is made of sturdy, rust-proof material, ensuring it passes the annual inspection without issues. If you're modifying, opt for low-profile, fixed plastic or carbon fiber splitters, keeping the height no more than 20 cm above the roof, and secure them firmly with screws—avoid flashy, adjustable, exaggerated wings. Always check the spoiler's stability to prevent wobbling. I once installed one on a sedan, passed the annual inspection on the first try, and even gained a bit of downforce. During regular maintenance, wipe it down to prevent dust buildup in the gaps.

Having driven family cars for years, my experience with choosing spoilers is to go for understated and minimalist designs. For example, those small ducktail spoilers that attach to the edge of the trunk, just a few centimeters in height, are unobtrusive. The vehicle inspectors mainly focus on safety and consistency with the factory setup, so fixed installations are more reliable than detachable ones. Last time I replaced my spoiler, I opted for a low-key black plastic one without any flashy additions like LED strips. Friends often ask me why I don’t install something cooler, and I simply tell them that the inspection rules clearly prohibit increasing the height or width of the vehicle body—otherwise, it could lead to towing. It’s also important to regularly check that the spoiler isn’t loose or chipped. Keeping things simple makes life easier.

As a young car owner, I love spoilers the most when it comes to car modifications, but I need to choose ones that won't affect the annual inspection. Small-sized fixed spoilers are the most reliable, like those carbon fiber lip spoilers, as long as they don't exceed height limits after installation. Ask the modification shop to recommend OEM-style options and avoid cheap knock-offs. During the annual inspection, the inspector will test the stability, so make sure the adhesive is strong or the screws are tight. From chatting with fellow car enthusiasts, I found that standard ducktail spoilers have the highest pass rate. Remember not to go for those large racing spoilers—they're too eye-catching and will definitely fail inspection.
