Perrin Positive Steering Response System (Zero)

Improve turn-in and increase handling prowess with the PERRIN Positive Steering Response System. (P.S.R.S.)

What is the PSRS?

P.S.R.S stands for Positive Steering Response System and simply replaces the front control arm, front 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.

OEM Bushings- Bad

Under braking and acceleration, the OEM bushing can flex enough for your wheel to move back and forth .500"! This deflection of the wheel causes drastic toe in and toe out changes under braking. The toe changes will cause steering wandering and an altered tire contact patch.

No Caster

The bushing in the Zero PSRS is centered like the OEM bushing. An alignment is not necessary after installation. Caster is the angle on which the steering knuckle rotates. Adding caster makes the car turn in faster by providing a larger contact patch as the wheels turn on the steering axis. To add caster choose the Offset PSRS.
