The H&R Sport Spring kit for 2007–2008 Audi RS4 (4.2L FSI, Quattro) lowers ride height to reduce fender gap, lower center of gravity and reduce body roll for sharper handling and a more athletic stance. These springs use shot‑peened 54SiCr6 spring steel and a progressive rate design to balance ride comfort and control; H&R’s top-selling, German-made springs are tuned for improved driving dynamics and a refined look.
