H&R 09-16 BMW Z4 sDrive30i/Z4 sDrive35i/Z4 sDrive35is E89 Sway Bar Kit - 27mm Front/21mm Rear

H&R Sport Sway Bars are designed for improved handling without lowering or affecting ride quality. They increase the suspension's roll stiffness, maintaining ride comfort and dramatically increasing cornering control, lateral stability, and grip. A unique feature of H&R Sport Sway Bars are the smooth, machined-like forged ends that, for specific vehicles, allow for adjustability in stiffness. The kit includes proprietary sway bar bushings made from a special urethane/Teflon composite that prevents squeaks and eliminates the need for lubrication. The sway bars are made from 50CrV4 steel for faster response times and smooth transitional function, and are 100% made in Germany.
