    I know that a version of an ML disk can be used as a cheaper version, somebody with more knowledge will confirm which. Do you have the 18z version or 17z?

    Google it mate. There has been a few threads about it on audisrs forum. Plus it should be engraved on the caliper if it is 18z.

    Yeah or measure the disc you have. Generally I heave read that the 17z use 330mm discs and the 18z use 350mm ones.

    If the calipers are 18z you want ML55 discs and either machine or file the centre bore 1mm larger, so 0.5mm all around, i run these and they work very well. View attachment 29935

    I'm not sure they have 18z stamped on them , i think there is a part number stamped into the caliper somewhere at the top edge.

    18Z is stamped into them, on the outside of the bridge section at the top.
