ok, going through all the numerous wheel/tire threads, I have run into some confusion:

- the wheel hub for the USDM RS6 is 66.6mm, isn't it? I keep seeing references to a 57.1mm....I am pretty sure that the hubcentric spacers I ordered were 66.6mm
- the stock wheel: 18x8.5, yes? The ET is 30mm? 33?
- Euro stock wheel: 19x9? ET?
