The PSR Holden Commodore VT-VZ Sedan Stage 3 Handling Kit is our premium package for the enthusiast who demands total control over their vehicle's handling balance and chassis setup. Taking the comprehensive front-end upgrades of our Stage 2 kit, we turn our attention to dialing in the ultimate roll stiffness synergy, maximizing front geometry adjustability, and locking down the drivetrain.

To balance out the massive 30mm front sway bar, we introduce an 18mm Heavy Duty 2 Position Blade Adjustable Rear Sway Bar. This precise sizing allows you to finely tune the VT-VZ chassis, providing immense front-end bite on corner entry while allowing the rear to rotate smoothly on corner exit. We also introduce Camber Adjustable Pillow Ball Strut Mounts for the front, removing rubber deflection at the top of the strut and allowing for aggressive camber tuning to maximize the tyre contact patch.

To ensure absolutely zero wasted energy in the driveline, this tier finalizes the rear end by adding a Rear Differential Mount Bushing Kit. By eliminating differential wind-up and pairing it with the solid IRS cradle bushes, you gain immediate, violent throttle response, ensuring every ounce of torque is sent directly to the rear wheels.
