Add rigidity and precision to throttle input control to your Subaru with Perrin's PERRIN Performance Sub Frame Lock Out Kit. Lock down the back end and give yourself more control 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 driveline 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 Impreza models including WRX and STi.
