Though I settled on 35psi hot, I had run anywhere from 33-37psi with the 660's.

I may try less camber and keep pressure at 40 on my next track day (could be a while) and I'll update with the results. When I do go out, the rears will be rotated to the front and vice versa, so it will be easy to see if the grooving, if any.
Interestingly, this problem occurred on my second track day with these tires. The first time out, I put about 80 track miles on and the tires were fine. On that first outing, I had a stiffer front sway bar and a touch of front toe out--other settings were the same as the second outing. Ambient temps were low 90's for both outings. Second track day was about 85 track miles.
NoHaveMSG, the pic of your tire tread after 4 track days looks remarkably uniform and good to me. I am curious if you know about how many track miles that was.
Thanks to everyone for your comments.
