Control Arm Lower, Inner Rear Kit of 6 Bushes (2 x Bonded Shell Standard Bushes) & 2 Tubes, suits arms with 60mm OD bushes. Tired and worn control arm bushes can have a negative effect under heavy braking allowing the car to wander, they can also deform under heavy cornering allowing the wheel alignment angles to change. This not only makes the car less easy to control but can also cause excessive wear to other suspension components and tyres. SuperPro have used their 20 years of market leading experience to develop a polyurethane bush to not only combat these issues but also lasts up to eight times longer than the original
