BMW Sway Bar Kits for BMW E90 M3 S65 4.0L

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.

Hotchkis Sport Suspension products have been developed with strength, reliability, fitment, appearance, and durability all factored into their products to ensure that customers are never left unsatisfied. Suspension components are exposed to not only the elements, but also constant ever changing forces that will push the limits of any performance component to its breaking point if not built to a superior quality. This is especially true in vehicles with lowered suspension. Make sure your suspension is ready for any abuse thrown its way with Hotchkis Performance Sway Bars.

Performance sway bars allow you to take corners aggressively while still keeping the wheels firmly planted and reducing body roll, all without reducing overall ride quality. Hotchkis sway bars feature powder coated tubular steel construction for maximum durability and stiffness. Every kit includes the essential components needed for an easy installation and to ensure you get the most from your sway bars.
