The PSR Subaru Impreza GR/GV Stage 3 Handling Kit is our premium package for the enthusiast who demands total control over their vehicle's drivetrain and chassis setup. Taking the comprehensive geometry correction of our Stage 2 kit, we turn our attention to locking down the driveline and eliminating the notorious rear-end float found in the multi-link chassis.

The factory pitch stopper and differential mounts allow for excessive drivetrain slop under hard acceleration. Upgrading to a PSR Front Adjustable Pitch Stopper and Whiteline Rear Differential Mounts completely locks the drivetrain down, resulting in crisper gear shifts and ensuring every bit of power goes straight to the wheels.

We also address the sloppy rear chassis by adding Whiteline Subframe Void Filler Bushes. Filling the large voids in the factory rubber mounts guarantees that your rear subframe is stabilized under heavy load, providing instant forward drive and unwavering stability without transmitting harsh vibrations into the cabin.
