On option a vs b, I would mock up some cardboard and put it on a full car to get a better idea. Aesthetically, you would want it to match the character of the car, rather than just looking at one piece of it.
I'm guessing those graphs are from CFD as well? Or is that actually wind tunnel data? Was the car body included in that, or just wing by itself?
Any idea what's going on at 110-120? Looks a bit like separation, but I would expect the speed of that to decrease as AOA increases.
Also, what's the data look like around highway speeds? From eyeballing it, looks like drag bottoms out at 5lb?
