Personal experience:
I've gotten to use the new Power 1 tires for 4 trackdays and a race weekend.
I used the Michelin slicks last year, but as usual in the spring when it is cold and the track temps are low I switch to DOTs (usually Pirellis) These have an amazing amount of grip. Off the first set I got 2 days of an advanced racing school, half of a track day and half a practice day. Both tracks were predominately right hand turns. So I flipped them, got another full track day out and half of a practice day of them. At the end of the practice sessions, I was just starting to spin up the rear coming out of a couple of the turns. The front felt great right up I decided to change the tires out.
2nd hand:
I heard from another guy that was using them that he got up to 80 laps out of them before he started to spin up the rear. He did feel the front start to slide at that point, but it was more predictable in the slide and how it came back to him. Unlike previous version of the tire. I'd take his word on the tires, as he is a vendor for these, as well as, Pirellis and Brigdestones and a wicked fast racer who has been riding since the beginning of time. (not really )
I'm liking these so much that I'm not going to go back to slicks this season, I've decided to stick with these.
