Yeah bob, you're recommendations were spot on.  I was not generating enough heat at WGI (temps were just shy of 160, with a wee bit of extra heat on the inside edges vs. outsides)... probably because I was driving like a wuss (ARMCOPHOBIA).

I was able to push the tires a lot more at Thunderbolt last week (that course inspires a lot of confidence due to the incredible surface grip and tons of runoff).  Best lap was a 1:36.47.  Anyway, 32 fr / 36 rr (hot) was about perfect for me at that track (translated to about 25/27 cold).  I have just over -2.5 degrees of negative camber front and rear.  

After 14 heat cycles on the tires, they are grippier than ever... in my opinion much stickier than the NT01s once up to temp, but a bit more finicky in terms of reaction to temp and pressure changes; and also slippy as hockey pucks when cold.  The NT01s were pretty grippy right out of the paddock and weren't quite as scary when cold.

How many heat cycles can I expect to get out of the MPSCs?
