The SuperPro rear sway bar mount bushing set for 2011 BMW 1 Series M (rear, 20mm) secures the sway bar and restores proper body control. OEM rubber mounts wear and permit play that undermines sway bar function; swapping in SuperPro bushings returns lost effectiveness and improves handling responsiveness, helping the car feel firmer and more predictable through corners.
