If this is not interference drag, I dunno what is.

Yes! This may be the next area of attack for me, to shield the inside sides of the front tires. Maybe mount some coroplast to the front suspension components so the shield can turn and move vertically with the wheel. That, plus adding some HD (Home Depot lawn edging) side fairing to keep what air does make it under the car from blowing out the sides.
In any case, yes, there most definitely is aerodynamic interaction between the vehicle underbody and the road.
