Real world benefits

Factory rubber bushes on the Z4 E89 can be soft and wear quickly. SuperPro’s unique polyurethane formulation resists deformation, cuts unwanted movement and delivers consistent alignment under load. The result is crisper feedback, better braking stability and a more connected front axle feel, without the harshness you might expect. Bushings are covered by SuperPro’s lifetime warranty for long-term peace of mind.
