Part Number: PSP-SUS-400Notes: PSRS KitManufacturer: Perrin Performance Perrin Positive Steering Response System (PSRS): Get the most from steering input with the addition of the PERRIN PSRS system. PERRIN's system increases steering response in corners by adding additional caster angle, straight line performance by preventing lift when accelerating, and installs easily by eliminating the squishy factory rubber mount. The increased width of plus size wheels adds enough leverage over the factory rubber mounts to literally pull the car side to side, even on slightly uneven pavement. This is extremely unnerving and can be completely eliminated with our PSRS system.
