The Perrin Rear Subframe Lockout is designed to eliminate differential to chassis movement between the rear subframe 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 Subaru for a price everyone can handle.
