H&R Sport Spring kit for 1989–1990 Porsche 911/964 C2 and C4 Coupe, Targa and Cabrio applications (2WD/AWD). The set lowers ride height to reduce fender gap, lowers the center of gravity and reduces body roll for improved handling while maintaining comfort. Progressive spring rates provide refined ride quality; shot‑peened 54SiCr6 springs and German production deliver a lightweight, durable and resilient upgrade that can also improve aerodynamic efficiency.
