The 911 didn't have PCCBs, nor did it have 20mm susp. w/LSD, x51 or CUP tires.
Well then AUTOCAR must have got it wrong because they stated that the 997S had Ceramics.
As for the differences between 18" and 19", your bloody right I believe there is a difference in the way they make a car behave and I have experienced it first hand.
