The PSR Subaru VA STI Stage 3 Handling Kit is our premium package for the enthusiast who demands total control over their vehicle's setup. If you are looking to build a serious corner-carving street car or a weekend track warrior, this package takes the comprehensive geometry correction of our Stage 2 kit and adds the ultimate in alignment adjustability and drivetrain security.

The biggest upgrade in this package is the inclusion of the Whiteline Rear Control Arm Kit. This completely replaces the factory rear camber arms with heavy-duty, adjustable units fitted with premium polyurethane bushes. This entirely eliminates rear suspension deflection and allows you to dial in massive amounts of precise rear camber adjustment, ensuring your rear tyre contact patch is always optimized.

To complete the drivetrain lockdown, we introduce a Whiteline Rear Differential Mount Bush Upgrade. High horsepower and aggressive launching will cause the rear diff to twist violently on its factory rubber mounts. Upgrading these bushes locks the diff firmly to the rear subframe, delivering 100 percent of your power directly to the ground!
