Once they are done I think I will move back to NT01s which is what I have run the most on my previous setups.
I guess the miles/laps metric depends on the average speed of the track, but the sessions I am in are usually about 20-25 minutes with some exceptions of longer sessions. So that's about 80-90 minutes a day? At Limerock, that would mean something like 75-80 laps a day maybe. At the Glen 35-40? I destroyed my front PS2s that came with the car in pretty much exactly 4 dry track days. Rears had more in them. I was a bit worried about using them again last week thinking they might be destroyed in the rain as well, but they held up fine then--obviously because of the slower speeds and lower temps.
