Cusco's Power Brace Seat Rail Floor Set adds torsional rigidity directly at the seat rail and floor mounting points, reducing body flex right where the seat, driver, and chassis all meet. Less flex here means the suspension geometry stays closer to its intended alignment under hard cornering loads, for a more predictable, connected feel.

Sold as a complete set of 2, one for each side, these braces bolt in using the factory seat rail mounting points — the only additional step is trimming the plastic trim that normally covers the rails to make room for the brace.
