The Cusco 40D front strut bar fits the FD3S Mazda RX-7 as a front strut-tower reinforcement, intended to stiffen the chassis around the front suspension mounts. By reducing tower movement it sharpens steering response and helps maintain suspension geometry under load. It’s offered as a replacement-style upgrade for RX-7 owners seeking a more direct steering feel.
