40d,
I'm in the minority here. I don't see the purpose of buying ANY of the OEM wheels as an "aftermarket" purchase. I think the $4K for a set of 21's ridiculous (not to mention the fact that you are held hostage by the limited 21'' tire market). I have OEM 214's and I'm tired of seeing them here in Knoxville. I've been in the market for 22's myself so, I'm down for helping you piss off the purists and give you some ideas.

I'm more of a "lip'ed" wheel fan, but I think the Vorsteiners would be a nice choice...a real nice choice.
