Reinforce Your Chassis with Cusco Type OS V-Brace

The Cusco Type OS Rear Add-On V-Brace is the ultimate reinforcement for your Subaru Impreza's rear end. Designed to work in conjunction with the Cusco OS Rear Strut Bar (666 541 A), this V-brace adds a third point of contact to the strut bar, creating a triangulated structure that significantly increases rear chassis rigidity. This setup is ideal for track enthusiasts and those who demand the absolute best in handling performance.

Important Installation Requirements

  • Triangulation: Dramatically increases rigidity by creating a stronger structure.
  • Required Component: Cannot be used without Cusco Strut Bar 666 541 A.
  • Wide Compatibility: Fits a broad range of Impreza models from the classic GC8 to the GDA/GDB chassis.
  • Professional Grade: Built to Cusco's exacting standards for durability and performance.

By triangulating the rear strut towers, you eliminate even more chassis flex than a standard strut bar alone. This ensures that your rear suspension remains planted, allowing for better power delivery and more predictable handling characteristics. If you already have the OS rear strut bar, this V-brace is the logical next step in your suspension build. Enhance your vehicle's structural integrity today with high-performance components from GGCRACING.
