Leave them polished! I'm all about black wheels, but I believe they at least need a polished lip or something to break up the monotony. I think your wheels look great as they are. If you're interested in changing the look without shelling out a ton of dough, grab some wheel spacers for the rear and throw on some 275s, and it will look badass. Your car looks sweet as it is. With the wheels totally blacked out, all I can think of is the Batman theme.
If I had a black stang (or any black car for that matter), I'd definitely do the "murdered-out" look. I think an all black car looks SICK! Powdercoat your wheels black and tint the rear tails FTW!
I just found this old thread of my cars wheels PS black. Debating if I should get a can of plasti dip tomorrow and give it a shot. It can't hurt right?
