Perrin [15-21 WRX/STI] Differential Lockdown System

Add drivetrain rigidity and precision to throttle input with the PERRIN Differential Lockdown System. The kit's CNC aluminum lockdown plates remove any and all movement from the rear differential under all driving conditions - from daily street driving to drag racing and road racing. Under hard driving the drivetrain twists and moves before turning the wheels, making initial acceleration feel numb and spongy; the PERRIN system locks the differential down for zero movement, reducing squat and eliminating delay in power transmission between the engine and wheels.
