Positive Steering Response System simply replaces the front control arm rear bushings. The OEM bushings are designed to be extra compliant to reduce NVH, and make the ride more comfortable. The compliancy of this bushing is not something a performance oriented driver is looking for. Eliminating the OEM super soft bushing provides significant improvement in how the car steers during hard cornering and even in a straight line. The bushing in the PSRS is purposely offset from center-line. This adds approximately 0.5 degrees of caster to the front suspension. Caster is the angle on which the steering knuckle rotates.
