These won't be very useful for the track. You might be able to get a session or two out of them but I wont use them for that and I'd use almost anything. These are among the best if not the best DOT race tires availible. Front is a supersoft compound, awesome for stoppies, and has tonnes of tread. rear is soft compound. It's really sticky as well. I did a few burnouts on it but there's still plenty more left in it. It'll actually cause your rear wheel to hop a bit if it's already warm when you try. I'd use them for street/stunt but theres lots left in my street tires now. $100, if you're stunting with them, I'll give you another 180/55 supercorsa rear tire to go along with the set.
