Spec Clutch ST33MT2C Mini Twin Carbon Conversion Clutch Kit

The Spec Clutch ST33MT2C is a high-performance Mini Twin carbon disc conversion clutch and flywheel assembly designed for Toyota engine and transmission swap applications. This specialized conversion kit enables the installation of non-original engine and transmission combinations, specifically facilitating builds using Toyota 5SFE and 3SGTE powertrain configurations.

Key Features:

• Multi-disc clutch and flywheel assembly for enhanced torque capacity
• Carbon semi-metallic disc material for aggressive engagement and durability
• Engineered for limited street, drag racing, and road racing applications
• Rebuildable design with replacement components available from SPEC
• Manufactured in the USA with SFI approval
• Available in different disc configurations and clamp loads based on usage demands

SPEC Mini Twin assemblies are specifically developed for high-performance builds requiring superior holding power beyond what single-disc clutches can provide. The carbon-based friction material offers excellent heat resistance and extended life under demanding conditions. Professional installation is required, and the flywheel must be resurfaced or replaced prior to installation. A minimum 450-mile break-in period with primarily city or stop-and-go driving is required before full-throttle engagement.
