I think that from my personal use of Carbon Ceramics on my Cayenne Turbo and California, they are a great option to have. The stopping power is PHENOMENAL!. So much better than anything I have experienced before in that department.
Another effect if that it lowers unsprung weight at the wheel. Helps with rotating mass.
Third, and for most cars, NO BRAKE DUST!!!!!
Good luck guys, and I am envious. I got rid of my 08 M5 that I bought new in July 2008 for a X5M (wow, was that a mistake). Missed my M5 very, very much.
Post some pics when they come in!!!!
