SUBKIT-003 Subaru Impreza GC8-GF8 WRX & STI PSR Stage 3 Handling Kit | Genuine PSR Handling Kit

The PSR Subaru Impreza GC/GF/GM 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 90s 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 Lock Bolts and upgrading the rear trailing arm lower bushes. Tying the subframe directly to the chassis and replacing the soft pivoting rubber guarantees that your rear alignment stays true under heavy load, providing instant forward drive and unwavering stability.
