Unless the beetle bolt pattern has changed from 5x100, you can't use 
it.  Most 5-bolt Audis (all except the TT) use a 5x112 bolt pattern.

I used the front hubs from a ur-S4 for the front of my cq, but haven't 
figured out the back yet.  I was told to use the rear hubs from a 200tq, 
which I have.  But I have not figured out which bearing to use.  The offset 
seem right.

Elijah, thanks for the info on the rotors and your hub information.
