Perrin Rear Diff Subframe Lockdown System

• 2004-2007 Subaru | WRX STI
• 2002–2007 Subaru | WRX

Add drivetrain rigidity and precision to throttle input with the PERRIN Rear Diff Subframe Lockdown System for the 2002-2007 WRX and 2004-2007 STI. The differential lockdown stiffens the front and rear differential mounts with 4 urethane bushings for zero movement under extreme conditions like drag racing and road racing, removing the "squishy" feeling at initial acceleration. The subframe lockdown solidifies the rear subframe against the chassis with 2 urethane bushings, metal sleeve washers and 2 bolts, eliminating driveline slop and the annoying 1st-to-2nd gear thud. A big improvement in overall feel for autocross, drift and drag racing.
