I gotta confess, it's not my car. (Not even an R actually).
Mine is somewhere betwween the factory and my dealers.
I'm not so keen on the standard Mk5 wheels, so have been playing about on the pc this weekend.
(I hear you lot are getting some sunshine, but it's 35degC C here, and inside is much more pleasant)
I think this look is a classic Dub style. Because the Mk5 is much smoother and less chunky than the Mk4, it reminds me of the Mk4 Polo from the late 90's. I think a euro look with some deep lipped rims would work well.
