2004-2006 GTOs suffer from poor brake pedal feel. The original radius rod bushing is a soft fluid filled bushing. This bushing absorbs most of the braking load as the car wants to keep moving and the wheel tries to stop. This results in excessive movement of the front suspension when braking. The original bushing has no caster adjustment. The Lovells Radius Rod Bushings X82047 corrects these issues. This Polyureathane bushings allows you to adjust the caster. This upgrade will dramatically improve braking and handling of the car. This is the number upgrade for the car....This is must do!! Installation is simple. Easy to follow instructions are included with the kit. If you can change your oil....you can change these bushings!!!
