Folks, Does anybody have a good source for the OEM Audi two-part lug bolts? (Other than the dealer...) Also, I'm looking for one or more B5 S4 17" wheels, 42 ETA. Turns out the spare on the A4 is a 38ETA and doesn't fit over the front calipers. (BIRA System 2). I think it might be a replica wheel with thicker spokes. Thanks! Lee
