Construction & Design

The Cusco Type-40 Rear Strut Brace features a meticulously engineered design that combines lightweight aluminum with robust billet aluminum ends. The hollow 40mm OD cross section is CNC-machined for precision, ensuring a perfect fit and consistent performance. The welded billet aluminum ends provide a solid connection point that resists deformation under high loads, effectively reinforcing the rear chassis structure.

The aluminum end plates are anodized in a titanium gray finish, adding corrosion resistance and a sleek appearance. The overall design emphasizes strength, lightweight construction, and ease of installation, making it an ideal upgrade for enthusiasts seeking to improve their vehicle's handling characteristics without sacrificing everyday drivability.

Performance & Sound

By installing the Cusco Type-40 Rear Strut Brace, you will notice a more rigid chassis, which translates into sharper handling and more precise steering response. While this component does not directly increase horsepower or torque, it significantly enhances the vehicle's ability to transmit driver inputs effectively, especially during high-speed cornering or aggressive maneuvers. The improved chassis stiffness can also contribute to a more confident driving experience and potentially better tire grip.
