Time for new rotors?
I know there’s a lot of posts like this, but I still can’t tell. Are these rotors done? This is after 5 sessions, 20 minutes each and about 1500 street miles. Didn’t expect they would wear so fast, but I guess I’m running DTC-30s.
Edit: can’t add a picture but there’s also small heat cracks in one of the rotors. The back 2 look good still. Can I just replace 2 at a time?
