Types of Driving: Street, Drag, Pulling, Autocross
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.
* High clamp pressure plate * Carbon-Graphite Friction Material * High torque solid hub and disc assembly * Bearing and tool kit

Billet Aluminum Pressure Plate Option:
Substantially reduces rotating mass, increases power and throttle response ,
adds infinite rebuildability
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. http://www.c5racer.com/catalog/product_info.php?products_id=485617
Comments: These clutch kits are designed for use with
SPEC flywheels or any aftermarket LS1/6 single mass flywheel. These kits
increase friction surface diameter to 12inches while reducing rotating mass by
up to 36%. The SC57 flywheels are for use with non-stock clutch designs. For a
flywheel to be used with the OE style clutch, use pn SC66A-2 or SC66S-2. The
package includes race bolt kit and tool. |
