Installing a rear spoiler is considered illegal and falls under unauthorized vehicle modifications. Driving a car with illegal modifications on public roads will result in the vehicle being impounded by traffic authorities, the illegal modifications being confiscated, and the owner being ordered to restore the vehicle to its original condition, along with a fine of 200 yuan. Conditions for legally installing a rear spoiler: First, apply for a modification registration: For vehicles with illegal modifications, traffic authorities will not issue a safety inspection certificate. If the modification constitutes a violation of public security management, the public security authorities will impose penalties such as fines or detention in accordance with the relevant provisions of the Public Security Administration Punishment Law. Register with the Vehicle Management Office: To install a rear spoiler, you must first register with the Vehicle Management Office. Only after approval can the modification proceed. After installation, the vehicle must be photographed at the Vehicle Management Office. The modification must not exceed the specified limits and must be approved to be considered legal. Article 16 of the Road Traffic Safety Law clearly states that no unit or individual may assemble a motor vehicle or alter its registered structure, construction, or features without authorization. Failure to comply will result in the vehicle failing annual inspections and routine traffic checks.

Should I go to a 4S shop or a repair shop for tire repair?

Tire repair within the warranty period is more secure at a 4S shop, while auto repair shops may be relatively more affordable, but with varying levels of technical expertise. Below are specific methods for tire repair: 1. Patch repair: This method is more complicated, requiring the use of a tire machine to remove the tire, grind the wound, apply glue, and then stick a patch after the glue dries. It takes less time and is cheaper, but the patch may fall off when exposed to water over time, making it suitable for small and shallow wounds. 2. Mushroom plug repair: This involves inserting a mushroom-shaped rubber plug from inside the tire, locating the wound, threading the mushroom root from the inside out, cutting off the exposed part, and then securing the inner part with special glue. The mushroom root provides an external repair effect, while the top of the mushroom plug acts as an internal repair. This method offers better and more durable repair results, but it is relatively more expensive and time-consuming, making it suitable for larger punctures. 3. Rubber strip repair: This method does not require removing or installing the tire or performing dynamic balancing, making it convenient and quick. However, rubber strip repair involves enlarging the original wound, which can cause some damage to the tire, and may lead to air leakage over time. 4. Hot patch repair: Hot patch repair is similar to patch repair, with the difference being that after applying the patch, a baking machine is used to heat the wound until the patch melts and bonds with the wound. Hot-patched wounds are very durable and are unlikely to leak again. However, hot patching requires strict control of heating temperature and time. If the heating is not properly managed, it may scorch the tire or even cause deformation in severe cases.
