The H&R Sport Spring kit for 2004–2006 BMW 545i (E60) with self-leveling lowers ride height to improve handling stability and reduce body roll while maintaining comfort. H&R's progressive spring rate provides a balance of control and ride quality. Constructed from shot-peened 54SiCr6 spring steel and built in Germany, these lightweight springs are a widely chosen upgrade to refine stance and help reduce aerodynamic drag.
