Product Description

The Cusco 3F7 492 SP is a seat-rail power brace set specifically designed for the 2023-onward Honda Civic Type-R FL5. This brace set strengthens the seat rail and floor area, significantly reducing flex in the cabin during aggressive driving and better supporting the structure when using performance or racing seats.

Built from high-strength solid steel and finished in Cusco's signature blue, the braces bolt directly to the factory seat rail mounts. The included safety-harness hook provides a secure point for lap belt-style harnesses, making this an excellent choice for track-focused setups.

With only minor trimming of interior plastics required, installation is straightforward. Once installed, the 3F7 492 SP delivers a more planted and rigid chassis feel, improving driver feedback, reducing unwanted seat movement, and elevating both safety and performance.
