Cusco Lower Bar Type I is a front lower arm brace made for the FC3S Mazda RX‑7 chassis. It stiffens the lower front structure to improve handling feedback and chassis response under cornering loads. The brace installs to factory attachment points and gives clearer steering feel and reduced flex for drivers who want a more connected front-end without altering suspension geometry.
