Construction & Design

The Cusco CF Carbon Rear Strut Bar features a meticulously engineered design utilizing 100% layered carbon fiber for the shaft, ensuring maximum strength while maintaining an ultra-light profile. The steel end plates are precision-painted in titanium gray, providing corrosion resistance and a refined look. The bar's diameter of 40mm strikes an ideal balance between rigidity and weight savings, effectively reducing chassis flex without adding unnecessary mass. Its bolt-on installation method ensures a secure fitment that aligns perfectly with the factory mounting points, making it a reliable upgrade for both daily driving and competitive motorsport applications.

Performance & Sound

While the primary focus of this strut bar is chassis reinforcement, users can expect noticeable improvements in steering response and handling stability during aggressive driving. The increased torsional stiffness minimizes body roll and flex, translating to more predictable and confident cornering. The lightweight carbon fiber construction also contributes to a slight reduction in overall vehicle weight, supporting better acceleration and braking performance. This component does not significantly alter engine sound but enhances the overall driving experience through improved chassis dynamics.
