The installation was quick and fairly straightforward, and the result was a factory-like clutch-pedal feel, but with extra grip. "We add this clutch setup to C6 Vettes, as well as to the DeNooyer Chevrolet HTR-edition Camaros," said Tanner. "It's a great clutch with a factory feel to it. Many of our Vette customers are concerned about the clutch, but also want the power. They don't want something that has too heavy of a pedal feel for everyday driving."
Thanks to the extreme environment of racing, the street enthusiast can now build the wildest engine combinations and have a clutch capable of holding the torque and horsepower-without getting calf implants just to step on the pedal.

Hotaling adds Loctite red to the flywheel bolts and torques it down to 74 ft-lb, using a stepped process and alternating bolts as if he were tightening wheel studs.

The ZR1 clutch stack is taller than its single-disc counterpart, so a ZR1-specific hydraulic slave is required. It's on the left, while the stock C6 slave is on the right.
Lining up the clutch is crucial...
Lining up the clutch is crucial with both the twin-disc and single-disc setups. Redline uses an input shaft for this purpose. The pressure plate is then bolted to the flywheel using 37 ft-lb.

One of Redline's tricks to getting the bellhousing back on is to loosen the front cradle and ball joints, and relieve the bottom shock nuts. The parts can then hang freely without being removed completely.

Loosening those parts allows enough room to squeeze the bellhousing back on. It's torqued to 35 ft-lb.

The rear differential, the transmission, the torque tube, and the trans-cooler lines are bolted back into the Vette. The rear axles are slid into the differential, and the rear cradle is reinstalled.
