Spec Clutch ST933FS Stage 3+ Carbon Semi-Metallic Clutch Disc

The SPEC Clutch ST933FS is a Stage 3+ carbon semi-metallic full-face clutch disc designed for high-powered street and race vehicles requiring exceptional performance with manageable engagement characteristics. This flagship stage disc delivers the perfect balance of aggressive torque capacity and driver-friendly operation.

Key Features:

• Carbon semi-metallic full-face friction material for unparalleled life and friction coefficient
• Sprung hub design with spring cover relieves for flexibility and vibration dampening
• Heat-treated components ensure strength and durability under extreme conditions
• Offers excellent drivability with comfortable pedal feel and quick engagement
• Superior wear characteristics under both low and high-stress usage
• Designed for street, drag racing, road racing, drifting, rally, and autocross applications

The Stage 3+ distinguishes itself from the standard Stage 3 by featuring a full-face disc rather than a puck-style design, providing smoother engagement and reduced chatter while maintaining high torque capacity. This makes it ideal for heavily modified engines that still require daily drivability. SPEC manufactures all clutch components in-house in the USA to ensure the highest quality control and precision.
