Crew, Specifics: I'm looking at a set of Ronal R28s. They were on a 1998 A4 1.8t Quattro; are 17x8.5, but the owner is not sure of the offset. General: If wheels fit a 1998 A4 1.8TQ, will they fit a '91 200 TQ (no UFOs; upgraded to S4/S6 front struts). Any BTDTs? TIA for your collective help and wisdom. Greg J
