ACT Heavy Duty/Performance Street sprung clutch kit for 1999 Ford Mustang. The FM9-HDSS pairs ACT's Heavy Duty pressure plate—with an exclusive diaphragm design and four-stage heat treatment—with a performance street sprung disc using premium organic materials, high copper content, and steel-backed lining for improved heat transfer and burst strength. Reduced marcel allows faster shifts; ACT backs the kit with a one-year warranty.
