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
The automotive component most responsible for insuring optimum
clutch performance and life is the flywheel. The flywheels
contribution to power transfer is three-fold.
Firstly, the flywheel should provide a consistent and friction
enhancing surface for the clutch disc. Flywheels also aid in proper
inertia, which is determined by the flywheel weight. Inertia
controls the ratio of power to acceleration and can make a vehicle
faster or slower based on gear ratio, tire type, vehicle weight,
power output and even the location in the powerband output is
achieved. The weight of a flywheel and amount of inertia it
provides can also effect drivability. Lastly, the flywheel must
provide a true balance at rpm, which means no dimensional runout
that produces engine damaging and power robbing vibrations and
allows smooth engine revolutions.
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 cars output
So far so good. just have to wait until the product arrives.
