In any case, yes, there most definitely is aerodynamic interaction between the vehicle underbody and the road.

Note that Mercedes and perhaps others have fairing/deflectors canted inboard in front of the front wheels. This because the relative wind is not straight front-to-back, but rather deflected ~60 degrees outboard. Best to do tuft testing to see what's up with your particular vehicle, whose dynamics may differ from Calibra.
