The Corsa 3's were awesome for grip and I would run them all the time if I could afford new tires every 3 months. The only thing I didn't like was that they are duel compound. They were great for 3000k but because the center of the tire is a harder compound, the sides wore out much faster giving them more of a diamond shape profile rather than rounded. Made the bike feel like I was riding on 10 speed tires (really jittery). It was a toss up for me between the M3's and the Pilot powers
