For those considering CCB for track use

I know this has been discussed quite extensively, but good to hear it from a solid source.

This one is on Porsche Carbon Ceramics and Andreas Preuninger says, if you do a lot of work on the road, you should have them, because they are lighter. However, if you do a lot of track work, you should stick with the steel rotors, because they’ll wear out and it is cheeper that way.

FF to 6:18 in the video (the whole video is a great watch though ):

Not to mention every heavily tracked GT3 i've seen has iron rotors. Even if it came with carbon rotors you see them retrofitted with iron.
