I have a 2000 a6 2.7t.. do i have 255mm or 245mm rotors??

First you need to find out which production number for the brakes that you have. Look inside your logbook or the spare tire well and tell us which of the following production numbers you have:

1LB, 1LE
1LT, 1LF
1LA, 1LG
1LX, T7Z
1LJ

Once you know that and post it here, someone will look in their Bentley Service Manual and tell you what dimension rotors you have.
