Yes, very interesting reading. Could be entitled "Cayman Faces Reality." If one can't stand the truth, one shouldn't read that stuff.

On the other hand, I've enjoyed tracking and autocrossing the OEM car for over two years with no apparent problems. I've been using Michelin Cup tires on track, so you might reconsider using one of the tread patterned R-comp brands that doesn't have quite the grip that the slicks-with-grooves type of R-comps do.
