The Cusco pillowball front lower arm front bushing kit is specified for GRB STi and replaces front lower-arm bushings with pillowball-style units. It tightens suspension control and helps preserve alignment under dynamic loads, making steering response crisper. Use this kit when refreshing worn bushings or when firmer front lower-arm articulation is desired on GRB STi models.
