i'm going to go against the grain here and say it would look great.
your car should be a representation of you and not the masses.
it has to be the right shoes though b/c i'm not crazy about some of the ones posted above. also, as someone else mentioned the gunmetal could look great, too. but it has to be the look your going after and i'm not sure you'd be happy with it. i mean, look how long you debate a mod for your car, even something as simple as mud flaps!
the look would definitely make it aggressive, and you may not like that.
