rs6 or s6 wheels

anyone know what size rs6 or s6 wheels can fit my 2000 a6 2.7t, if any. Also, if you can answer the previous question, where can i find them on-line?

You should be able to fit either wheel easily. The True RS6 wheel is "Light alloy wheels 8.5 J x 18 RS 30 in 9-spoke design" (from Audi training material.) That should fit with out complications. Same as the stock sized S6 wheel. Personally, I like the design of thr RS6 wheel better. You kind of get sick of the S wheels, and look forward the seeing the RS wheels rolling into the shop.

where can i get those online, or at the dealer?

Would 245/35/18 fit with that setup? Or what do you think is a good tire size for 18x8.5 so as not to have too skinny of a tire (i'm in NY) :-( .... Thanks
