I would not run the race or power ones unless you get the street compound power ones. I can't get the bstone 016 to last, they were only good for 2 days and the 2ct's I had on before that went 15 (this is a mix of N-I-A and one race).
This will depend on the tires used and the track you go to. I have 13 days on my pilot powers right now and they are still on the bike. This is a combination of intermediate and novice with a race thrown in too.
They last longer than 2000 miles. Hell the set of Pilot Powers on my bike now have been through 8 novice and 8 intermediate track days and I now have 1500 street miles on them. If you get off the highway they will last longer.
