[SanAvery]

The new regulations for car modifications are as follows: Wheel rim style: The new regulations have relaxed the rules for wheel rim modifications. As long as the size and specifications of the wheel rims match those on the registration certificate, the style can be changed, and it is even permissible to have four different wheel rim styles. Installation of roof racks and side steps: This new regulation mainly targets SUV and MPV models. The height of the installed roof rack must be within 300 millimeters, and the width of the side steps must not exceed 5 centimeters beyond the side profile of the vehicle. Body color: If the body color is changed through painting or wrapping, the vehicle information must be updated at the vehicle management office within ten days. It is important to note that colors similar to those used by police cars, fire trucks, etc., are not allowed. Grille and front/rear bumpers: The installation of new grilles and bumpers must not alter the original length and width of the vehicle. Modifying the vehicle emblem is prohibited, and the bumpers must not have any obvious protrusions. Roof racks are allowed: However, the installation height must not exceed 30cm, and modifications must be carried out under the premise of ensuring safety and stability for passenger vehicles.
