The SuperPro rear sway bar mount bushing set for 2011 BMW 1 Series M (rear, 19mm) replaces worn mounts to keep the sway bar properly located and restore roll control. Worn rubber bushings allow unwanted movement that reduces sway bar effectiveness; upgrading to SuperPro bushings can return lost sway bar performance and sharpen handling for a more controlled, predictable ride.
