The FX725 twin‑disc race kit (requires FW‑738‑TDA) pairs two ceramic rigid discs with a billet Type‑3 hard‑anodized cover for reduced flex and higher tensile strength. Clutch Masters’ QR Quick Release system evens engagement and can cut internal chatter by up to 50%. Aluminum flywheels are billet 6061‑T6 and SFI 1.2 spec machined, while steel flywheels use 1045 billet with black oxide treatment for competition durability.
