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.

Adjustable sway bar end links are an absolutely critical component for anyone who is serious about extracting the best possible handling from their M car. By varying the length of each link slightly, the alignment technician can ensure that the sway bar is completely unloaded and unstressed at static ride height, giving the car excellent chassis dynamics and truly even corner balance.

Lowering your car is often the first step in suspension tuning, but occasionally, this process can adversely affect other associated components. Unwanted sway bar pre-load may be one of these consequential effects, adding asymmetrical spring rate bias to one side of the car versus the other. This imbalance may affect your overall chassis dynamics and corner balance. For this reason, adjustable sway bar end links are critical—by adjusting each link with the car at operating weight, you can ensure the sway bar is completely unloaded at your determined ride height, restoring your chassis' balance and your confidence in all driving situations. Unlike all other link kits on the market that utilize the cheaper and simpler jam-nuts, Fall-Line utilizes OE tie-rod end style pinch-nut fasteners to ensure they never lose their set length. NOTE: New V2 photos coming soon! V2 Key Features: Now includes OE tie-rod end style pinch-nut fastener rod ends Eliminates the typical jam-nut rod ends that are known to move over time Designed for superior corner balancing Ensures equal weight distribution on each tire Compatible with height adjustable dampers Eliminates uneven cross-weights Prevents sway bar-induced suspension stress Allows for precise customization through length variation Includes dust boots to protect against dust interference Made in USA Sold as a pair
