SPEC flywheels are CNC manufactured at an unheard-of .001 tolerance. 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. Provides a consistent and friction enhancing surface for the clutch disc. Also aids in proper inertia, which is determined by the flywheel weight.
To allow for specific inertia needs, SPEC flywheels are made in high carbon billet steel. 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. All SPEC flywheels carry SFI certification.
*Will accept the original V6 clutch or SPECs 5.0L clutch kits(CK139-CK145).
