the abridged version is longer distance around lowers static pressure and increases dynamic pressure, there's a higher pressure in the bubble under the jeep, the air going down the skid would accelerate, creating a boundary layer. lift, i think suction would be more likely; that's if you take away the side wakes, and gusts of wind.

High pressure under the car means lift. It's like a stationary fan blade pushing air down. Better than bare axles, etc. but not as good as an aero undercarriage. Anyway, glad to hear the smooth surface is working out.
