Nothing to see here...
Lies, damn lies, and statistics.
I'd be willing to bet 9 out of 10 track racers will take a stock gt3 over a stock carrera S for the win.
That said, I love the new 991 and hope they keep going as they have been.
I know it's not the most technical of tests, but 5th Gear did back to back laps (of Rockingham) of the basic 991 and the 997 GT3 (on corsa tyres) and the GT3 was still quicker. But not by much. I'd imagine the GT3 with less artificial aids would have been more fun though.
