Fachsenfeld, who did the research at the FKFS, addresses the relationship in his book,' AERODYNAMICS DES KRAFTFAHRZEUGS', 1951.
The turbulent wake behind the wheel acts in a stabilizing fashion, like the wake behind the transom of a ship / boat, tends to 'center' the stern in the direction of travel.
If you look at a recent ROLEX' 24-HOURS of DAYTONA race car, you'll see a fin behind the Jaray greenhouse, running the total length of the aft-body. Exactly like Fachsenfeld had done prior to the beginning of WW-II in Europe. This weather-vane compensates for some of the loss of the exposed wheel wake, and with zero drag penalty.
