The Ironman Sprung (Street) clutch kit for 1979–1982 Mazda RX-7 (1.1L 12A) combines American Sintered Iron friction with a dual clamp-load heavy-duty pressure plate to maximize torque holding. It produces aggressive, on/off engagement without excessive chatter, though light engagement noise or gear rattle can be present. Intended for high-powered, non-daily race applications, each kit is inspected and signed off for consistent performance.
