My 612 (164158) which first hit the road in May of 2009 has 91k on the clock. According the diagnostic computer at the dealer: Front Carbon brake disk: 45% wear Rear Carbon brake disk wear: 45% Pads 35% worn all around, although it is not clear if the pads were changed at any time prior to my ownership (which has put 63k of the 91k on her). Clutch 15% worn with 23k kms since she was changed. Usage is mainly GT with a bit of Nurburgring on the side. I am hoping to get 150k kms out of the carbon disks...fingers crossed. Bill
