Methods for adjusting the kingpin inclination angle: 1. For MacPherson suspension, adjust the hard points; 2. For double-wishbone suspension, adjust by adding shims to the upper control arm. When observed from one side of the vehicle, if the kingpin tilts backward, it is a positive inclination angle; if it tilts forward, it is a negative inclination angle. The kingpin inclination angle mainly affects handling in two ways: first, its impact on the camber angle, and second, steering feedback and straight-line stability. With a positive inclination angle, during steering, the inner half-shaft moves downward relative to the road surface, while the outer half-shaft moves upward. Therefore, the kingpin can be considered as the rotation center of the wheel hub.

Length: Length is the parameter that most significantly affects a car's purpose, functionality, and ease of use. Therefore, vehicle classes are typically categorized by length. A longer body means more longitudinal usable space, which is obvious; however, an excessively long body can make turning and parking inconvenient. 2. Size classification: There is a notable difference in driving feel between a 4-meter-long car and a 5-meter-long car. Generally, small to medium-sized passenger cars are around 4 meters long, while those approaching 5 meters can be considered large cars.
