SPEC Flywheels & Pressure Plates -
The automotive component most responsible for insuring optimum
clutch performance and life is the flywheel.
SPEC Flywheels: are CNC
manufactured at an unheard-of .001 tolerance, in an industry where the
standard is .010. This precision manufacturing process ensures perfect
balance and a perfectly flat bedding surface for the clutch disc, both
of which also contribute to the ultimate in safety for competitive
environments. All SPEC flywheels carry SFI certification.
To allow for specific inertia needs, SPEC flywheels are made in high
carbon billet steel and aircraft quality billet aluminum. The aluminum
and most steel SPEC units are rebuildable and feature a replaceable
steel friction plate that is made from a friction- enhancing steel
metal specially formulated for optimum clutch bedding and holding
power. The aluminum and steel materials provide a light and medium
weight option for all types of racing. SPEC spends a lot of time and
effort on research and development of optimum flywheel dimensions and
weights for all types of driving and racing and can optimize your MOI
(moment of inertia), to maximize your car's output & performance.

SPEC Pressure Plates: SPEC
manufactures aluminum pressure plates for many applications. These
pressure plates are designed for OE fitment, but can be used with an
array of transmissions and flywheels. The benefit of the aluminum
pressure plate is comparable to gains from a lightweight flywheel, and
in most cases is less costly.
For years lightweight flywheels have been used to transfer energy from
an engine to the ground more efficiently, resulting in horsepower and
torque gains, quicker revving and less internal engine wear. The SPEC
aluminum pressure plates offer the same benefits, and the reduction in
mass is more effective since the pressure plate extends further from
the crank flange.
These plates can be used with an OE flywheel or in conjunction with
a lightweight flywheel for a more drastic improvement. Drivability
is virtually unchanged, and the aluminum plates offer the same high
clamp loads, and in some cases more clamp load, than the standard
steel SPEC high performance pressure plates. SPEC uses only aerospace
quality aluminum and fasteners and most SPEC aluminum pressure plates
carry SFI certification.
