Hey Sean - just a quick note to let you know I made it back to Sydney ok and just got around to replacing all the rotors/pads on the A8 with the Stop-Techs and couldn't be happier. No hidden fitment issues and they are definitely in the same category (if not better) than the local DBA 4000 rotors I have used on my other cars. I've got a few before and after pics showing the stock Brembo rotors/pads from Audi and the Stop-techs fitted up. Think i'll be in the Market for a set of the calipers next! Thanks Sean.
