From everything ive read on here and a few other forums, the TDR Pro Race 1.2 wheels seem like the best bang for the buck in terms of relatively light durable track wheel that is relatively plug and play for the RS4 B7 platform.
It seems like the best size is a 18x9 so that i can run wider tires, and an offset 20mm?
My questions are; does the size listed above fit without any adaptors or adjustment?
Where is the best place to buy these wheels, price vs avail?

Also does anyone do good wheel/tire packages for this wheel, i guess the size to run is a 265/40/18 or 275/40/18, do both of these sizes fit without any adjustment? Good tire deals or best bang for your buck track tire for this wheel?

thanks in advance
