Each kit contains: 4 high performance low friction ball joints and 4 lightweight, friction reducing control arm bushings. • Less bind = lower lap times. • Assembled kits for easy ordering. • Reduced suspension “stiction”. • Increases ability to transfer weight. • Precision machining promotes front end alignment during usage (unlike O.E. rubber bushings). • Kits contain lightweight lower bushings (nylon inserts for reduced weight and less friction).
