In one or more track reviews it was stated that the TT was "more buttoned down" or "firmer" than the S. Are there real differences or were the TT testers loaded up with pasm, as, pdcc and ptv and their little brothers not?

Think I've read that the stock S is slightly better balanced with a f/r weight distribution of 52/48 vs 54/46 TT. Also, wouldn't the unsprung weight be ever so slightly less in the S with smaller wheels and tires and slightly smaller brakes?

If the above is true AND there are no suspension differences, what is behind the car mags giving the button down and firmer nod to the TT? Real differences? Or do the larger tires and brakes make for better suspension.
