Any C6Z tested this clutch ?

 

I'd suggest locating a car that makes alot of midrange torque, which really kills clutches, like one of the current TT setups, or something like Scott's(Divexxtreme's) proposed supercharger setup.
Most N/A setups don't make enough midrange torque to really tax a clutch, which is why the typical Spec and Tex clutches usually suffice.
