Spec Clutch SN66MT3 Mini Twin Multi-Disc Clutch and Flywheel Kit - X-Trim

The SPEC SN66MT3 Mini Twin Multi-Disc Clutch Kit is a high-performance, multi-plate clutch and flywheel assembly engineered for demanding performance driving. Designed to handle the rigors of limited street, drag racing, road racing, drift, time attack, pulling, and rallye applications, this X-Trim kit delivers the clamping force and durability that serious performance builds require.

SPEC's Mini Twin platform is available in a range of clutch disc and flywheel materials, clamp loads, disc configurations, and diameters — allowing the setup to be matched precisely to the intended driving environment. The twin-disc design spreads load across multiple friction surfaces, delivering higher torque capacity without requiring extreme pedal effort.

Key Features:

• Multi-disc clutch and flywheel assembly for high-performance applications
• X-Trim configuration suited for street, drag, drift, road race, time attack, pulling, and rallye use
• Manufactured to an industry-leading .001-inch tolerance for optimal rotational balance and concentric actuation
• Rebuildable by SPEC or the end user — replacement components and rebuild services are always available
• Flywheel and track-spec hardware included in the kit
• Available in multiple disc materials and flywheel configurations to suit specific driving demands

Installation Note: A new flywheel or properly resurfaced existing flywheel is required. A minimum 450-mile break-in period of primarily city and stop-and-go driving is required before full-throttle engagement, drag launching, or speed shifting.

SPEC clutches are manufactured and developed for specific driving environments, offering the ideal balance of engagement feel, torque capacity, and long-term durability for performance-oriented builds.
