Perrin Subframe Lockdown Subaru WRX STI 02-07

The Perrin Rear Sub-frame Lockdown 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.
