Spec Clutch SC07A-2 Aluminum Flywheel SFI Certified Billet Lightweight

The Spec Clutch SC07A-2 is a precision-engineered aircraft-quality billet aluminum flywheel designed for high-performance and competitive driving applications. Manufactured to an industry-leading .001 machine tolerance — ten times tighter than the industry standard of .010 — this flywheel delivers a perfectly flat, friction-optimized seating surface for the clutch disc and exceptional rotational balance at all RPM levels.

Reducing rotating mass is one of the most effective ways to unlock drivetrain performance. Aluminum construction makes this flywheel significantly lighter than a stock steel unit, resulting in faster engine revving, reduced drag on the drivetrain, and quicker throttle response. Less rotating mass means more of your engine's power reaches the wheels.

Key Features:

• Aircraft-quality billet aluminum construction — approximately half the weight of a comparable steel flywheel
• CNC machined to an ultra-precise .001 tolerance for perfect balance and a flat clutch bedding surface
• Rebuildable design with a replaceable steel friction plate formulated for optimal clutch bedding and holding power
• SFI certified for competitive and racing environments
• Engineered and developed for specific driving environments to optimize Moment of Inertia (MOI) for maximum performance
• Suitable for street performance, drag racing, road racing, drifting, autocross, and rallye applications

The flywheel's role in clutch performance is critical — it must provide a consistent friction surface, contribute appropriate rotational inertia for the application, and maintain true balance to eliminate engine-damaging vibrations. SPEC engineers each flywheel to a specific application's MOI requirements, ensuring the ideal balance between power transfer and driveability. The SC07A-2 is rebuildable, making it a long-term investment in performance.
