I'm not so sure. I had the same tires before this set and got about a similar wear rate with those. They didn't last as long because I waited too long to rotate them.
I usually run about .03 degrees of toe out for the track...forget what the street setting was. At this point, 50+ sessions out of a set of tires...I'm very happy. Way better than the conti slicks...4-8 sessions.
