I also run a 808 '10 spec, and was wondering about the carbon fiber option dics. A buddy of mine( sponsered xray driver) swapped these in on his '10 spec, during the initial build. Just to try them out after running the stock metal disc setup on his '09 spec. He says that they stop very well, but notices that they start to fad during long mains( 30+ mins.). He recommends the advantage gen2 dics( blue ones) over the xray carbon discs.
