The SuperPro DuroBall control arm bushing kit for 2011 Subaru Impreza WRX STI front lower inner delivers the precision of a spherical bearing encased in polyurethane to reduce deflection and restore crisp responses. It improves steering feel, alignment stability and tire wear compared with worn rubber bushes while retaining cabin isolation. The design suits daily driving and heavier-duty setups where bush wear accelerates with larger tires and wheels.
