The Audi-authorized brake replacement procedure used parts from the S4.  I
think the calipers/pads/rotors are the same as the S4.  Don't know whether
those numbers are the same as the 5k or not, but I think they're the same.
What is different, I think, is the wheel bearing and its housing and some
attached parts.  I think they're beefier than on the 5k cars.  Some of the
later conversions, not done by Audi as a response to a complaint, but
rather paid for by the customer, used 5k parts because they were available
used or cheaper originally than the S4 parts.
