Pirelli Diablo Corsa's seem to work well for me. I got about 10 track days on them and the rear is just about worn out. These tires are 80% track use and 20% street use, but they are not like race tires that need a few laps to warm up. In good weather conditions they stick on the first turn on the first lap. I tired this at Pocono the second day I had them on, first lap frist turn I went in at full speed and they stuck, amazing. I rode Super Corsa's before and they needed a lap or 2 before I could get on them. I have heard of endurance racers that used the and they worked just fine, so they can double as a race tires too.
