on the new Saleen Mustangs, they actually DOWNSIZE the wheels when you go for the higher performance options! Sure, eventually either the dub craze will wain, or it may thrive and will appear even more on new cars, but wheels that big are alot of extra weight(unsprung at that) and will NEVER be a part of the real racing world, unless we find a way to make steel weigh .00000000000000000000000000000000001 lbs.
So, let them have their fun and think that they are men.
