The ALTA PSRS replaces the front control arm's rear rubber bushings with solid spherical bearings. The solid design of the PSRS will not allow any wheel deflection under heavy braking or acceleration, in turn your MINI's suspension geometry will not change making the vehicle handling more consistent and predictable.  Under acceleration your MINI will have more front end traction and be more predictable in corners. Wheel hop will disappear and your MINI will feel more stable. Under braking steering feedback issues and wandering are eliminated!
