The H&R Sport Spring kit for 2007–2011 BMW 335i Sedan (E90) lowers ride height to tighten fender gaps and lower the center of gravity for reduced body roll and improved handling. The progressive-rate springs aim to retain comfortable ride characteristics while enhancing cornering stability. Constructed from 54SiCr6 spring steel and shot peened in Germany, these springs are a popular single-part upgrade for a sportier stance.
