Suspension springs
Depending on the model and equipment, several types of coil springs are installed on vehicles in combination with upper support cups of various thicknesses.

Selection of a suspension spring with an upper support cup
Four types of springs and support cups are used on cars in the front suspension. The selection of the spring and the support cup is made at the factory and must be maintained throughout the entire period of operation in order to avoid deterioration in the stability and handling characteristics of the vehicle.
When replacing the spring or support cup, be sure to install identical parts.
The spring to the support cup is selected according to the sum of points. This amount is the sum of the model score and the optional equipment score.
