This unit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub. Best for drag racing, road racing, pulling, rallye and drift.

The Super Twin is for street and track use in cars with extreme horsepower and torque (700-1500 ft lbs tq). The Super Twin offers near-stock drivability, tremendous life expectancy, a no shimming/setup bolt-in installation and maintenance free operation. With all billet construction, these units are smooth and quiet. The units are rebuild-able by SPEC or the end user and replacement components or rebuild services are always available. The super twin is constructed with aircraft grade aluminum and high carbon billet steel milled to an industry leading .001 inch for perfect balance and actuation. Friction is provided by dampened, full-faced carbon graphite discs. Organic, fiber and full metallic options are available. Flywheel and track-spec hardware are included in each kit. Types of driving: street, drag, drift, road racing, time attack, pulling and rallye.

Multi-disc clutch and flywheel assemblies for limited street, drag race and road race applications. The Mini Twin assemblies are available in different clutch disc and flywheel materials, clamp loads, disc configurations and diameters which are recommended based on the type of usage the vehicle demands. The units are rebuild-able by SPEC or the end user and replacement components or rebuild services are always available. SPEC manufactures to an industry leading one thousandth of an inch for perfect rotational properties and concentric actuation, which optimizes balance, drivability and life. Types of driving: limited street, drag, drift, road racing, time attack, pulling and rallye.

SPEC billet flywheels are manufactured and developed for specific driving environments and recommended based on how each car reacts to changes in rotating mass. SPEC flywheels are NOT a one-fits-all lightweight flywheel, though they can be used for an array of driving habits and racing/high performance applications. Consult a SPEC representative for a recommendation. Manufactured from only the highest quality steel and aluminum, they are the only flywheels on the market manufactured to a .001 machine tolerance, guaranteeing a flat seating surface for the clutch and smooth rotational qualities for perfect balance and extended engine life.

SPEC Super Clamp pressure plates have extreme clamp loads that are beyond what is offered in the standard high clamp kit. These pressure plates will provide a marginally higher pedal requirement, but are engineered to have reasonable drivability and not be a detriment to the car’s release system. Expect a 50-60% increase in clamp load above and beyond the increase offered by our standard high clamp pressure plate.
