H&R Sport Springs replace the factory coils with a progressive rate design that lowers the car approximately 1.2 in (30 mm) at both axles, closing up the fender gap while reducing body roll and dropping the center of gravity. The springs are made from 54SiCr6 spring steel and shot peened for fatigue life, and the progressive rate keeps ride quality civil on the street rather than trading comfort away for stance. This kit is calibrated for cars fitted with PASM Sport suspension and retains function of the front axle lift system. Made in Germany.
