SPEC Flywheels & Pressure Plates -
Porsche
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.
