Spec Clutch SA00MTR-2 Mini Twin R-Trim Multi-Disc Clutch and Flywheel Kit

The SPEC SA00MTR-2 Mini Twin R-Trim is a high-performance multi-disc clutch and flywheel assembly engineered for limited street, drag race, and road race applications. With a torque capacity of up to 800 ft-lbs, this kit delivers serious holding power while maintaining street usability for drivers who demand performance across multiple disciplines.

The R-Trim configuration features a carbon composite, full-face disc with an unsprung hub, offering a balance of aggressive torque capacity and manageable engagement characteristics. The Mini Twin design uses dual clutch discs, providing significantly higher clamping force than a single-disc setup without the bulk of a full-size twin-disc system.
