Add rigidity and precision to throttle input control to your Subaru Impreza WRX or STi with the PERRIN Performance Sub Frame Lock Out Kit. Lock down the back end and give yourself more controlling power. Kit includes polyurethane bushing inserts and bolt-in frame lockouts to completely lock-up the rear sub-frame, differential and trailing arms. This eliminates all drivetrain slop and especially the annoying thud from first to second gear changes that are found without this kit. An inexpensive upgrade that nets such dramatic results. Fits all Impreza models including WRX and STi.

4 urethane differential lockout bushings
2 urethane differential support beam lockout bushings
