I'm at 420hp now and the stock clutch is basically the same as the GT3 with much more hp. Not a problem and the action is perfect. The RUF guys install the stock clutch up to 600hp all day every day so I went with their advice and its worked out fine. The stalling is kind of like the reverse clacking. Pretty much a crap shoot on whether your car will do it or not.

Did Ruf provide the part number of the pressure plate they installed?
What cam grind do you spec?
