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. |
