H&R Sport Spring kit for 2009–2013 Infiniti G37 Sedan (3.7L V6, non‑AWD) lowers ride height to close the fender well gap and improve handling via a reduced center of gravity and reduced body roll. The progressive spring design balances firmer control with retained ride quality. Made from shot‑peened 54SiCr6 spring steel, these lightweight German-made springs are a widely chosen H&R suspension upgrade.
