I had the newer model RS4 replicas in 17" on my 2003 - sadly, no photos.
They did look good though!
I regret not pulling them when I traded it in.
Try looking in the Group Buy forum - the clear/ smoked bumper marker (RAH) has photos of a B5.5 in Silverstone Gray with the RS4's, I think.
I have a set of 18"s. They're classic and look good, but I wish I'd have gotten 19's. Either way you go, it will look great. IMO they look too much like the 2001 A4 17" Ultra sports, but with a little bit of dish, I'd suggest you go at least 18" or larger. Good luck. Try www.thewheelexchange.com/ less than $1500 shipped for myself + great service. BTW don't get the Nitto's if you plan on driving in the wet.
