I am not an aero expert, but does seem to me that two feet is not enough clearance for the ground effect to be minimized.

Why??

Ever been on a narrow two lane country road, and have an opposing car go by? Notice the large blast of air that pushes the car sideways as both cars pass by each other?

The clearance between the the two cars from the centerline of the road to each car is about two or three feet at best, yet not enough to diminish this effect.

I would think that based on this phenomena, that something closer to 8 feet would be the minimum, just from observation.
