Add rigidity and precision to throttle input with Perrin Performance’s Subframe Lock Out Kit.

Lock down the back end and give yourself more control.  The 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.

This is an inexpensive upgrade that nets truly dramatic results.

Fits impreza models including WRX and STI.
