Product Information

H&R Sport Springs are a progressive-rate lowering spring kit that lowers the car approx. 1.4 in at the front and approx. 1.3 in at the rear, closing up the gap between tire and fender, lowering the center of gravity and reducing body roll. The progressive spring rate design keeps ride quality and comfort while the car sits lower. Each spring is made from (hf) 54SiCr6 spring steel, shot-peened to extend its service life, and 100% tested before it leaves the ISO 9001 certified H&R plant in Germany. On the RS7 the rear drop is approx. 1.2 in.
