The MINI Cooper has a problem with wearing rear tires because of excessive factory camber settings on the rear wheels, this becomes a much bigger problem once the car is lowered. This SPC camber arm set allows your alignment shop to adjust the rear tire camber to reduce tire wear and increase the handling performance. This camber arm set is strong enough for the track but also works great on the street. For maximum camber adjust on extremely low or race cars use 2 sets, one for the lower lateral links and one for the uppers. Set includes 2 camber arms, one for each side of the rear.
