 |
The Perrin Postive Steering Response Kit (PSRS) is an anti-lift kit (ALK) designed to preven lift under acceleration in cornering.
HOW IT WORKS: The PSRS relocates the reare mount of the front control arm, increasing the caster angle for better turn-in and response. This design will also control wandering from uneven pavement or larger wheels and tires.
Perrin has recently redesigned the kit to use Delrin bushings for zero deflection and elimination of noise for trouble-free operation. The 6061 aluminium housing makes for a strong, precise part. A 10-15% increase in noise, vibration, and harshness should be expected as the stiff mounts absorb less road noise.
