The H&R Sport Spring kit for 2008–2015 Smart Fortwo (451) drops the ride height to reduce fender‑well gap and lower the center of gravity for better handling and less body roll. H&R’s progressive spring design preserves ride comfort while firming stance; the springs are shot‑peened 54SiCr6 steel, block‑set and produced in Germany to provide lightweight strength and dependable long‑term performance.
