I've thought about it too, although I can't make up my mind if I like it or not. Not enough to do it myself, put it that way, but it does go with the racing blue and stripe combo. Would look better if it was lowered too.
The missus wheels were slightly damaged anyway so needed to be refurbished at some point, but she wanted something different.
As I said, in my opinion anthracite goes with silver, black, red etc. But racing blue with gordini stripes just doesn't suit anthracite. White stripes, white wheels and although the standard alloys aren't that amazing, they look better in white than anthracite on this colour.
In mine and the missus opinion. Seems a bit like marmite for most though, love it or hate it. At least its different though.
