Alta Positive Steering Response System (PSRS) – For MINI Cooper & Cooper S | SKU: AMP-SUS-112

Upgrade your MINI’s steering precision and handling feel with the ALTA PSRS. This system replaces the rear rubber bushings in the front control arms with performance urethane bushings. Expect sharper, more consistent response under acceleration, braking, and cornering—especially with wider tires or more aggressive driving.

Key Features:

• Replaces the OEM control arm rear rubber bushing with stiffer polyurethane for improved steering feedback and reduced deflection.

• Helps prevent wheel hop, wandering, and unpredictable steering under heavy load or rough surfaces.

• Offers 0 to +1.5° of added caster when installed, improving straight-line stability at highway speeds with minimal steering effort.

• Durable material and design—polyurethane bushings outlast OEM rubber in all but the most extreme conditions.

• Includes all necessary hardware, grease, stickers, instructions, and ALTA 5‑year warranty.
