When they start to crack or the lip is significant ... usually get a season out of them.
Btw, rotors do not warp (99% of the time). It's usually pad deposits causing puling from a bad bed in. I would stay away from any chinese rotors, but any German or Italian made Brembo, Balo, Zimmerman, etc are all pretty much indentical quality. In fact, I like the Zimmerman better since they are coated so the hats don't rust.
