I've been reearching wheels a lot lately as I wait to pick up my kit in a couple of weeks. I've gone to more wheel sites than I can remember. What kind of look are you after - retro, original, or custom? What size (15, 17 or ?) Do they come in the right offsets for your body? It all depends on the look you want your final car to have.
Personally, I'm going custom with either a Foose or a Coddington design. I don't want to get caught trying to make my "replica" look like an "orginal" or "real" cobra.
