Better than nothing if they could "rough measure" the car.

Then do a "sweep" on Cd from .46 to .55

While a production car is fairly level, a race race has more of a wedge shape to it. With a much greater ground clearance in the back than the front. Where do they measure ground clearance and how well will that work with this formula?
