So, you're replacing the UFO hubs (which don't fit in normal Audi rotors cause they're too wide) with either modified UFO hubs, or with S4/V8 hubs?
As I recall, there were a few places that rented such a tool for cheap (plus deposit); think Wolfsport or one of the VW places in NY.  Might also try a FLAPs, they're pretty good about having tools for loan/rent.
You can also search the audifans quattro list for more info.
