Gosh, what's up with the hostility? Just because people have been burning out clutches, doesn't mean this person's information can be inaccurate. He's also a fellow i-Clubber, whom I don't think deserves to be called an idiot.
On the other hand, we certainly would have heard about it, had our WRXes had clutches as nifty as the one described.
On the other other hand, I believe that a kevlar clutch disc does not, of necessity, mean a grippy clutch, and perhaps they changed the clutch component parts to something more organic, so that people would stop complaining.
Just some thoughts.
