Spec's Super Twin clutch assembly uses two smaller discs to handle more power than a conventional clutch. The complete package comes with a billet-aluminum flywheel with a replaceable steel surface ring. The billet-steel floater disc rides within the billet-aluminum cover, providing surface area that's nearly twice as much as a single-disc clutch setup. Best of all, pedal effort is significantly less than stock. Owners of '03-'04 Cobras can certainly appreciate that.
