Also I vote for my ceramics. I test drove a 580 in rain and afterwards I had to admit that its brakes were really good, as good as the ceramics. After getting out the car I saw why ... it was a 580 with the 20"Mimas wheels (standard is 19") and CCB options (standard are the "wafe" rotors from the R8). Before I bought my Spyder I went for a testdrive with another 580 that had steel brakes. No stopping problem at all but the CCB felt somehow more immediate, even in rain.

But I agree with those who track the car as you change the rotors/pads anways after each race and dust is not your major concern. I tracked the H with CBB a day in Imola and I really loved how they behaved. Unfortunately the instructors always forced us to do a cool down lap as it was a +30°C day. But I did not feel any need for that
