The Cusco Power Brace Seat Rail Plus is designed to increase chassis rigidity and floor stability in the Honda Civic Type R FL5. By connecting the left and right rear ends of both seat rails, this brace reinforces the cabin floor area, reducing flex and improving handling precision under load. When used in combination with other Cusco chassis bracing, it significantly enhances overall structural stiffness compared to the factory setup.
The Seat Rail Plus kit also includes an integrated safety harness hook suitable for lap belts, making it ideal for performance driving or track use. The lightweight design provides additional rigidity without adding unnecessary weight to the vehicle interior.
