SUBKIT-045 Subaru Impreza GR-GV WRX PSR Stage 5 Handling Kit | Genuine PSR Handling Kit

The PSR Subaru Impreza GR/GV Stage 5 Handling Kit is our absolute top-tier, no-compromise package. If you are building a dedicated track weapon or the ultimate street car and demand nothing but the absolute best, this is the final evolution of GR/GV suspension tuning. This package includes every single component from our previous stages and adds the final pieces to the alignment and chassis rigidity puzzle.

With the camber arms already upgraded to adjustable units in Stage 4, Stage 5 completely replaces the factory trailing arms with Heavy-Duty Adjustable Rear Trailing Arms. This removes the final weak link in the multi-link rear suspension, allowing for precise adjustment of your rear wheelbase and anti-squat geometry while eliminating all flex.

Finally, we address the inherent flex of the front chassis. To combat structural twist under heavy cornering loads, we include a Whiteline Front Strut Brace. Tying the front strut towers together prevents the chassis from twisting, ensuring the suspension components absorb the load directly as intended!
