The optional 17" wheels from a VW dealer, together with 17" rubber to match will cost you both arms and a leg if you buy from the dealer -- about $900/cnr is the go. Therefore, you are better off seeking out wheel options from various specialist dealers. There is an Oz Racing wheel that is very similar to the R line, plus many other options.
You will need to stick very closely to the original circumference, so there's really no need to get five wheels unless you are a perfectionist!
