Deep Dish Wheels & Drag Coefficient??? So the trend today in cars, you see them from the Civic to the Maxima, and Camaro to BMW, is the deep dish style aftermarket rim (in most cases it is aftermarket). What is this doing to the car's aerodynamics? I recall the Aero package on the 80's Trans Am brought the drag coefficient pretty much to the current z06 at .29 largely by putting all but flat faced rims on the car.
So...
What is the Drag Coefficient change of deep dish wheels?

I don't think that it's all that much, ESPECIALLY at public road speeds. The wheels on the T/A were more hype, than anything else. The spoiler and side skirts probably helped a bit, but then those cars sat SO high from the factory, at least mine was, that I doubt the quoted aero drag numbers were on the money...

Actually, I was wondering quite the opposite. I have read a couple, albeit internet and unreliable, people's opinions who say that the deeper dish actually improves drag coefficient over the thin spoke design seen on so many factory and aftermarket wheels i.e. my SS 10 spokes. If it is as efficient as Honda's Civic hybrid rims to have a deep dish, that would make them pretty impressive. I'm not diluted enough to think that it would shave a tenth, or add a couple mph, or even appreciably improve mph. I would flatten the undercarriage with abs plastic first, and I am not about to do that!
