Yesterday I noticed that my front driver-side rotor has little cracks all over it.
It's not warped, though. There's spots on it that are shiny, and the tiny hair-line fractures extend outward (center to outside) and are only about half an inch in length. I can post pics later when I'm home.
I take it I need new rotors? It's obviously not good that one rotor is like that, but how bad is it? I want to get new rotors anyway, but don't have the money for all 4. I was thinking of just getting a front pair, maybe those iRotors that I saw in someone's post.
But yeah, not trying to get sidetracked. So, how "gone" is my rotor?

Cracks wont go away or fix themselves. I wouldnt like to see a chunk-o-rotor go flying off at 75mph. That could cause quite a problem. OEM rotors are so cheap at parts stores these days, its silly to run a crippled one.

If they are surface type cracking then that is an indication of a LOT of heat being transmitted to the rotors, mostly due to driving style.
It's normal and I have run rotors with tiny surface cracking on a road course without incident. It happens and it's no big deal.
But, continue to drive the way the rotors indicate and it soon will be a big deal.
