I tried to answer your question already, but didn't quite get it.
I'm guessing the rear wheel is getting disturbed air flow so the pressures both positive and negative do not reach the same amplitude heights/depths as full free flowing air causes up front. Sort of like the tractor propeller verse the pusher propeller, the air going into the pusher will always be disturbed, causing loss of power or less efficiency.
All that negative pressure (sucking) on the leading edge of the front wheel causes me to wonder if covering the front wheels is more effective than covering the rear wheels.
I found an example of a partial front wheel cover in the forum.

A reference to the car below by name is made in that thread:
Ferrari 250 Testa Rossa (#0710TR) '11.1957

Lots of room for improvement, almost anything will make it better.
EDIT-1:
I found this in a Volvo forum.

Looks like the front wheels are double the drag of the rear wheels.
Also in the Volvo forum.
