IMHO, carbon ceramic brakes are a pure vanity purchase on a street car. They will not give you shorter stopping distances and are not necessary to avoid fade under anything resembling normal street use. If you track your car once a week then maybe ceramics make sense, but I refuse to believe that anybody who buys an M5 (as opposed to an M3 or even a 911) is going to track their car more than a couple of times a year. Yeah, brake dust is a pain, but the $8,700 (U.S.) the carbon ceramics will cost you buys an awful lot of professional hand detailing sessions.
As for weight savings, the difference between carbon ceramic and steel brakes is pretty slight and is likely offset on the M5 by the need to equip the car with the larger and presumably heavier 20' wheels in order to accommodate the carbon ceramic brakes.
Thanks, but I'll pass.
