Not sure.....

I have a set of 1 1/2yr old AP's that have a lot of surface cracking but nothing that's reached the outer edge. And none that are opening up....I saw a crack in a solid rotor at Mid Ohio earlier this year that concerned me. It wasn't very long and wasn't near the edge but was opening up. I pointed it out to the owner and sure enough it split wide open, all the way to edge, the next session.
