Be interested in this myself, cost of the carriers has been putting me off, do you think they would fit an A3 8p with 288mm discs at present? Also what would your understanding be of the term re-manufactured? Be interested to know where they come from and what he actually does to them as I see he has quite a few sets.
Well they are just a cast piece of metal, so it would just be a case of blast clean, and powder coat I would imagine.
As for fitment I don't have a clue mate as I've only just come over to Audi from 10years of VW's.
Just bought a set of these, as above, fit my 05 A3 TDi fine, trick was to match the numbers on the existing carriers, tells you how to do it in the listing. Good quality product, seller's a genuine guy (met him as I picked them up, he's only about 20 miles from me) and price was 75 for the pair.
