Types of Driving: Street, Drag, Pulling, Autocross
Features a
multi-friction disc in a full faced configuration with carbon semi-metallic on
one side and Kevlar on the other. Bridging the gap between stage 2 and stage 3,
the 2+ offers drivability and engagement quality characteristic of the stage 2,
but with a 15-20% higher torque capacity. The hub is double sprung with spring
cover relieves for flexibility and heat treated components for strength and
durability. Great for street, drag, autocross, road racing, pulling, rallye and
drift.
* High clamp pressure plate * Hybrid Kevlar and
Carbon-Graphite Friction material * High torque sprung 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.

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.
