Car suspension system spring modification

The modification of the spring is mainly to improve the controllability, that is, to use a harder spring or a shorter spring. The spring controls many factors related to the control, and the change of the spring will cause very complicated changes in the control characteristics. In terms of the increase in hardness, it can improve the suspension's rolling restraint ability and reduce the rolling of the body when cornering. The reduction in vehicle height can also reduce the center of gravity of the vehicle body, reduce the weight transfer of the vehicle body when cornering, and improve stability. The reduction in vehicle height can also take into account the aesthetic effect.
