What to get. MPSC, Dunlop SSR or Pirelli Corsa. I will only be using these at the track. Both the Dunlop SSR and Pirelli Corsa seem to be 250-300 less a set then the MPSC. I want to be able to flip the tires from one rim to the other to maximize use. I haven't read a lot about the Corsa or the Dunlop SSR. It seems the MPSC is the fastest and best handling. Does it wear 25-30% better then the others to make up for the price difference? Thanks a lot.
