I find the above rigidity dialogue interesting. I'm not sure what this means. I wonder if anyone has noted any practical difference between the 2 model years (i.e. performance, handling, track times, etc...). To me, stats can be used in whatever way the statitician likes, to prove a point. Pragmatically, I'm not sure I've ever heard anyone suggest that a stock o1 vs later models was any different where it counts -- performance. would be interested if there were a difference since I now know that I own the high and mighty 2001 TT.
