I'm still using the factory rotors as they calipered just fine within spec at 132k. I just put on some standard Bendix ceramic for under $20. Didn't even turn my rotors because they were smooth as glass as I live in the south. Made sure to service the slide pins of course. As far as durability, you just can't beat the factory rotors so if they are still within spec, I see no reason to replace.
Basically they feel factory new with a nice progressive pedal dynamic.
