I had seen it mentioned in previous threads that a convex wheel disk is more aerodynamically efficient than a flat one.
Since the convex one sticks out into the wind and increases frontal area, how can it be better than a flat one ?
Thanks

After seeing the awesome disk that Orange4Boy is doing on his Prius, I wanted to ask the question again, but didn't want to 'jack the thread.
