Perrin Diff Lockdown for 2008-2014 WRX/STi (PSP-SUS-535)

The Perrin differential lockdown kit for 2008-2014 WRX/STi adds drivetrain rigidity and precision to throttle input by reducing movement from the rear diff. Under tough driving conditions, the drivetrain and differential will twist. This causes a "squishy" or "spongy" feel on initial acceleration. This kit will lock the differential down for significantly reduced movement and better driver feel.
