Looking to improve your car's handling in the corners? ECS Tuning's rear non-adjustable sway bar is a cost-effective way to limit body roll and keep your wheels planted when entering a corner at higher speeds. Sway bars are a great way to improve handling without sacrificing ride quality or reliability! Sway bars are typically sold as a front and rear set to balance the handling. But a rear sway bar only can also have excellent benefits, especially on a street car. Going with a larger rear bar will improve steering and handling even at low-moderate speeds. ECS has specified a 15mm sway bar that has been fine-tuned for use on the E9X and E82 models. Urethane bushings with a reinforced inner core that requires no lubrication are included.

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: Installed photos show V1 jam-nut style 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
