Product Information
H&R Super Sport Springs have the features of the Sport Spring with additional lowering: this progressive rate kit drops the car by an amount that depends on the model and factory suspension (see the lowering rows below), lowering the center of gravity for sharper handling while keeping a comfortable ride. The springs are made from (hf) 54SiCr6 spring steel, shot-peened, and each one is tested before it leaves the ISO 9001 certified H&R plant in Germany.
