Apologies, I had it bookmarked
Paneled bottom diffuser thread - Corner-Carvers Forums
Lots of reading on underbody treatments, and how they've applied it.
As far as the wheels, they outline a solution on that thread that helps stop air from stagnating in the wheel well. The front undertray funnels air in inboard of the wheels.
Fairings for the rear wheels, and wind deflectors in front of the fronts are two options, as well as smooth hubcaps. Turbulence and pressure from the rotating wheel is the big issue. You can keep the air out, and you can help it leave easier, but the wheels have to turn and they'll always create some drag. If you look at endurance and other race cars, they typically include vents on top of the fender and behind the wheel arch. Whats tricky about referencing motorsport is they have very different goals than you do, although drag is very much on their radar they will trade it for a grip advantage
