twin disk clutch

Unless you're going drag racing with really sticky tires, or you're going to repeatedly strap your car down to the chassis dyno so it can't break traction, I don't think it really matters on a mostly street driven car that only has 600 lbs on each rear wheel. My crappy Yokos break loose if I give it any sort of throttle, like maybe 200 ft/lbs or less of throttle. I think a cardboard driven disk and a pressure plate made of bobby pins would hold it all together and the tires just break loose when the torque gets cranking.
