The PSR Subaru Impreza GR/GV Stage 4 Handling Kit is designed for the serious enthusiast looking to extract every ounce of grip from their AWD platform. Taking the incredible foundation of our Stage 3 kit - including XYZ Coilovers, comprehensive bush upgrades, and drivetrain lockdown - we introduce the ultimate in alignment adjustability and anti-roll technology.



The biggest upgrade in this package is the inclusion of the Whiteline Rear Control Arm Kit. This replaces the factory rear arms with heavy-duty, adjustable units to eliminate suspension deflection and allow you to dial in massive amounts of precise rear camber adjustment.



To keep the chassis perfectly flat through high-speed corners, we introduce an upgraded Whiteline Front Sway Bar to match the rear, along with heavy-duty Front and Rear Sway Bar Links. These upgraded links guarantee zero flex and instantaneous load transfer from the chassis to the sway bars.
