My friend recently installed a spec twin disc in his C5 Z06. Complained of the stiff pedal as well. He changed the master out to a 5/8 bore and pedal went back to stock feel. I have 5k miles now on my 5.5" Tilton triple disc (installed in January) and 30 passes at the drag strip on it. Love how this clutch wakes the car up. If you decide to use a non OE style hydraulic release bearing you will need new plumbing from the reservoir as well or get creative like we did and flare some -4 fittings and kept the quick coupler.
