I bought a second set of the forged magnesium BBS REs that were a little rough. I had one refinished in the standard BBS silver to replace a cracked wheel in my current set. I'm having the rest refinished in Anthracite to be used as my track wheels.
The original color set will be for sale in a month or so at somewhere around $3000. These are NOT street wheels. They'll crack on the first pothole.
This might give the RAC guys an idea of what the anthracite (British Black) might look like.
Sorry for the crappy phone pics.
