I installed a KC clutch when I put my Tremec in this past fall.
So far (500 miles or so), I'm very pleased with it. Pedal effort is easy. Definately a little more "grabby" (is that a word?

) than the old stock one that it replaced, but the old stocker was much more worn.
I'm close to 350 FWHP and it works very well for my application.
Good luck,
E
