The H&R Sport Spring kit for 2011–2016 BMW 550i (F10) reduces ride height to tighten handling and reduce the fender‑well gap for a cleaner look. Its progressive spring rate lowers the center of gravity and reduces body roll for improved stability and cornering response, while offering a slight aerodynamic advantage. Made in Germany from 54SiCr6 spring steel, shot‑peened and lightweight to maintain comfortable, durable ride quality.
