Perrin Subframe Lockdown Kit Subaru 2002-2007 WRX / 2004-2007 STI
The Perrin Rear Sub-frame Lockout is designed to eliminate differential to chassis movement between the rear sub-frame and the uni-body.
Acceleration and throttle response is improved and much more linear - very important for autocross, drift, and drag racing.
The Perrin piece will eliminate all flex between cornering, acceleration and braking forces being applied to the suspension and chassis.
This Perrin kit offers such a big improvement in the overall feel of your car for a price everyone can handle.
