    Hello,

    I currently have a B5 S4 and am considering a brake upgrade using callipers and disks from a B7 RS 4. I am running S8 18” wheels which are ET40 with 10mm spacers (so ET30), and I know that leaves me tight as RS wheels are ET24. I could perhaps go 2mm thicker on the spacers without getting clearance issues in the arch and that might work, but before buying anything I would feel a lot more comfortable if I could get some accurate sizes for the B7 calipers.

    Has anyone seen a drawing anywhere giving the major dimensions?
    Is anyone using a set with S8 wheels?

    Thanks,
    -----
