Of course.  The yellow carbon ceramics are about a $65k option on most 911s except the GT2/3/RS.  That $65k can change quite a few set of steel rotors and pads.  Also, the longevity seems to only apply to street use.  Some CC kits were finished after 2 track day events, which is why some GT3RS owners deliberately choose the steel no cost option or keep another set of steels for track day use.

As for my personal experience on bmw/merc/volvo, it is as Clayton c-hing mentioned.  The rotors lasts on average 2.5 set of pads, which is extremely annoying because you either throw away the rotors with some life left or you have to go back and change them half way through a set of pads.  I had a E46 which chewed through front rotors like pizza but the rears were prestine throughout the time I had it.  The minimum rotor thickness is stamped on the side of the rotor hat, so the best way to find out if they are still ok is just to grab a caliper and measure it, making sure to not measure the lip which sticks out.

I still maintain that nothing will coat the front wheels with brake dust faster than a set of oem bmw pads.  You take it for a wash and before you leave the parking lot gate, they're already black again.  Sigh...
