Perrin Diff Lockdown for 2015-2022 WRX/STi (PSP-SUS-536)

The Perrin differential lockdown kit for 2015-2022 WRX and STi models 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, causing a "squishy" or "spongy" feel. This kit will reduce that movement for a better driving experience.
