H&R Sport Spring kit for 2009–2016 BMW Z4 sDrive30i/sDrive35i/sDrive35is (E89, with sport suspension) reduces ride height to refine stance and handling by lowering the center of gravity and cutting body roll. The progressive-rate springs maintain a comfortable ride while improving responsiveness. Constructed from shot‑peened 54SiCr6 spring steel, these lightweight springs are produced in Germany and are H&R’s best seller.
