Granted, something like having a virtually non-existent wheel well gap on the inside of the front wheel for a standard shaped car (and almost no air gathering behind the front wheel) may be ideal, but
A) How can you fabricate something like that, that eliminates almost all air entering behind the front wheel, around brake lines, the steering rod, the suspension, and other parts?
B) For what air does gather right behind the front wheel, is it actually better to just let it sit there vs. form a vent to drain any air pressure behind the front tire out the side and thus add pressure behind the front tire's low pressure area?
I understand that it's ideal to fair the entire tire separately from the rest of the car body ALA that salt flat car design (option "C"?), but being able to custom-fabricate something like that is honestly beyond me.
