The Mini rear suspension layout is excellent. It allows you to have a good recovery camber and a good positioning of the roll center. On the other hand, in track use and during sporty driving, an increased negative camber angle becomes necessary. The only limit of the original suspension is precisely the fact that it can not be adjusted: the standard control arms does not allow this adjustment and unfortunately are mounted using rubber bushings. Our kit replaces the two standard upper control arms with tubular steel arms and adjustable motorsport rod ends with zero backlash. This allows the adjustment of camber and eliminates the previous play the rubber bushings allowed. The result is the optimization of the footprint of the tire when cornering and therefore the performance of the vehicle in terms of the traveling speed and entrance of the curve as well as higher stability.
