The H&R Sport Spring kit for 2004–2006 BMW 545i (E60) without self-leveling lowers ride height to reduce fender gap and improve cornering stability. The progressive spring rate reduces body roll while preserving ride comfort. Made from shot-peened 54SiCr6 spring steel and manufactured in Germany, these lightweight springs are a popular H&R upgrade to sharpen stance and offer modest improvements to aerodynamic efficiency.
