Today I confirmed it. The stock clutch in my 2007 Cobalt SS (Hahn turbo swapped for supercharger) is on the way out. I knew that it was only a matter of time with the increased HP. Are there any recommendations out there for a heavier duty performance-oriented clutch that will stand up to the engine upgrade? I'll nose around the net but maybe some of you guys can point me in the right direction. Thanks.
