The PRC front is glue! The rear could use a little more life, but the front is the shiznit. I have not run the new Pirelli, but i have a friend who says he will let me
New compond that came out late last year. Just order it and get bigger undies for the boner you will have
We use Michelin's and are very happy with them. The PRC front and PR3 rear combo works great most places for sprint racing.
PRC front has a more triangular profile and different construction than the PR1, PR2 fronts. The PRC is much better. PR3, PR4, PR5 are the rears. PR3 sticks the best, but has the shortest life.
