If it is necessary to modify this car, it should be reported to the manufacturer before the car is picked up, and a notice allowing naked car modification should be issued. After completing the modification within the scope and time specified in the announcement, go to the vehicle management office for licensing.
Power modification and chassis modification are generally not accepted by the factory, because the products of the factory have passed many tests, and we can't meet the standards of the manufacturer. In other words, the product launched by the manufacturer may be the most suitable for the vehicle.
