Spec Clutch SV87S Steel Flywheel High Performance Racing Flywheel

The SPEC SV87S is a precision-engineered steel flywheel designed for high-performance street and racing applications. Manufactured from high carbon billet steel, this flywheel delivers the optimal balance of durability, inertia control, and power transfer for demanding driving conditions.

Precision Manufacturing:

SPEC flywheels are CNC-machined to an exceptional .001" tolerance—ten times more precise than the industry standard of .010". This precision manufacturing ensures perfect balance and a perfectly flat bedding surface for the clutch disc, maximizing clutch life and performance while eliminating power-robbing vibrations. All SPEC flywheels carry SFI certification for competitive racing safety.

Key Features:

• High carbon billet steel construction for maximum durability
• CNC-machined to .001" tolerance for perfect balance
• SFI certified for racing applications
• Rebuildable design with replaceable friction plate
• Friction-enhancing steel surface optimized for clutch bedding and holding power
• Engineered inertia characteristics for improved power transfer
• Eliminates dimensional runout and vibrations

Performance Benefits:

The flywheel's weight and inertia are carefully engineered to optimize the power-to-acceleration ratio for your specific application. Steel construction provides medium weight characteristics ideal for maintaining drivability while improving throttle response and acceleration. The replaceable friction plate ensures long-term performance and allows for cost-effective rebuilding when resurfacing is needed.

SPEC invests extensive research and development into optimizing flywheel dimensions and weights for various driving conditions, allowing you to maximize your vehicle's moment of inertia (MOI) for peak performance output.
