BMW Sway Bar Kits for BMW Z Series E85/6 (2003-2008)

Clear BMW chassis

Please ensure your correct model is selected

The next step in tuning your car's handling - after shocks/springs and camber plates - should be a set of swaybars. Using larger front and rear sway bars will give your car better/quicker turn-in and less bodyroll in corners. These bars replace the existing sway bars on the car for a clean and simple upgrade with very little downside. Sway bars should be matched with your springs/shocks to maintain a proper handling balance. In some cases only a front or rear bar is needed to positively change the balance and make the car more neutral. We sell sway bar kits from H&R, Racing Dynamics, OE BMW upgrades, and even some of our own designs. Swaybars are sold with new bushings. New links and other hardware are strongly recommended.

    H&R Sport Sway Bars are designed for drivers who desire improved handling without lowering or affecting ride quality. H&R Sport Sway Bars increase your suspension’s roll stiffness—or its resistance to roll in turns—while 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—giving you an unmatched level of precision and performance.

    The sway bar on your vehicle is essentially a connection between the left and right lower control arms. When you take a corner in your vehicle, the sway bars flex and rebound like a spring. If the sway bar links are broken or worn, the system doesn't work as it should. Replace your end links and get all the performance characteristics back. New end links help you take turns better with less body roll. Some symptoms of failure are loose cornering, knocking noises, and a sloppy feeling when hitting bumps. They are very easy to replace and can be done by any automotive enthusiast.
