The SuperPro rear sway bar mount bushing set for 2009 BMW Z4 sDrive30i (rear, 23mm) replaces worn mounts to keep the sway bar correctly located and effective. Old rubber bushings can lead to sloppy suspension behavior; installing SuperPro replacements reduces unwanted movement, returns sway bar performance and helps the car feel more controlled and consistent during cornering and daily driving.
