Four issues with ceramic
1) They cost $5000 for each rotor
2) They chip very easily, and once chipped, can lead to a failure - so need to be replaced.
3) They transfer more heat into the pads and fluid (the yellow calipers have a bunch of features, like ceramic pucks between the pads and pistons, to keep the heat out)
4) They chew through pads faster and rotors last about 2-3 times as long as OEM steel.
And as far as I can tell, as long as you don't overheat the steel rotors with race pads, which I have yet to do, the PCCBs offer no improvement in performance. NOW, I have not driven it on a brake heavy course. COTA at the BMW event in June will ultimately tell me the answer to this. Even if I did have a problem...I still don't think I would run PCCBs - they are just too baller for me. I put the PCCB rotors in the attic for the next owner.
Interesting info on the ceramic rotors.
Enjoy the car. I know I would!
