The Cusco pillowball front lower arm rear bushing kit is listed for 2008–2010 Subaru GRB STi models and replaces rear bushings on the front lower arm with pillowball-style components. It tightens suspension articulation for crisper response and preserves alignment under load. Install this kit when refreshing bushings or when firmer front lower-arm support is needed on the GRB STi.
