Fits 2003-2008 BMW Z4 (2.5i, 3.0i, 3.0si, M Coupe, and M Roadster).

H&R Sport Springs are the premier upgrade for BMW Z4 owners looking to enhance both vehicle aesthetics and handling dynamics. These springs lower the vehicle's center of gravity and reduce the unsightly fender well gap for a more aggressive stance. Engineered with a progressive spring rate, they minimize body roll during cornering while maintaining a high level of ride comfort for daily driving. By reducing wind resistance, these springs also contribute to a more streamlined aerodynamic profile.

Crafted in Germany from high-tensile 54SiCr6 spring steel, each spring is shot-peened to increase service life and resistance to fatigue. The block-set design ensures the springs will not sag or lose their original height over time, providing a reliable, long-term suspension solution.
