Spec Clutch ST33MT2870 Mini Twin Multi-Disc Clutch Kit

The Spec Clutch ST33MT2870 is a high-performance Mini Twin multi-disc clutch and flywheel assembly engineered for serious performance applications. This complete kit is designed for limited street use, drag racing, road racing, drifting, time attack, and rally competition where exceptional torque capacity and precise engagement are critical.

Key Features:

• Twin-disc design provides significantly increased torque capacity over single-disc clutches
• Complete kit includes twin clutch discs, pressure plate, billet flywheel, and all necessary hardware
• Manufactured to industry-leading 0.001-inch tolerances for perfect rotational balance and concentric actuation
• Rebuildable design allows for end-user or SPEC servicing with readily available replacement components
• Billet aluminum flywheel reduces rotating mass while maintaining structural integrity
• Hand-built and tested in the USA with premium materials including high-carbon steel and aircraft-grade aluminum
• Optimized clamp loads and disc configurations based on demanding performance applications

SPEC Mini Twin assemblies offer superior drivability compared to traditional race clutches while delivering the holding power needed for modified engines. The precision manufacturing ensures smooth engagement, extended component life, and optimal power transfer. Installation requires proper break-in procedure of 450 miles of primarily city/stop-and-go driving before full performance use.
