ALTA 02-12 Mini Cooper/S/JCW (Incl. 05-12 Convertible) & 09-12 Clubman Pos. Steering Response Sys

ALTA 2002–2012 Mini Cooper/S/JCW (Incl. 2005–2012 Convertible) & 2009–2012 Clubman Positive Steering Response System

The ALTA Positive Steering Response System (PSRS) replaces the front control arms' rear rubber bushings with stiffer and more durable polyurethane, improving the handling characteristics of your MINI and enhancing your performance driving. Under acceleration, the MINI will have more front end traction and be more predictable in corners. Wheel hop will disappear and the MINI will feel more stable. Under braking, steering feedback issues and wandering are eliminated. The OEM MINI bushings are made of soft rubber to reduce noise, vibration and harshness (NVH), and make the ride more comfortable, in turn this creates a large amount of wheel movement under braking, accelerating and cornering. The more rigid design of the PSRS eliminates suspension misalignment making the MINI handle consistently and predictably during all driving conditions, including extreme driving. By offsetting the center pivot of the ALTA PSRS, the installer can add between 0 to 1.5 degrees of caster to the front suspension, giving better directional stability and reducing tendency to wander. The special urethane bushings will outlast the OEM bushings for years of performance driving.
