SPEC Stage 3+ clutch kits are primarily intended for street use, drag racing, pulling, and autocrossing. As the flagship stage for a high-powered street or race car that requires a manageable and friendly engagement, Stage 3+ clutch kits feature carbon-graphite full-faced material that offers unparalleled life, friction co-efficient, and drivability in one package. Their hubs are double-sprung with spring cover reliefs for flexibility and heat-treated components for strength and durability.

Note: SPEC flywheel required for proper operation, part number SC57A (Aluminum) or SC7S (Steel).

Break-In Procedure (opens in new tab): A minimum of 450 miles, primarily city driving with frequent stop and go situations, before full throttle engagement, drag launching or speed shifting. Failure to follow these steps will hinder the performance of the clutch and void the warranty. SPEC will not warrant any component failure due to installation errors.
