Is the material water-
proof, not just water-resistant? I'm thinking that it may need that protection
plus gravel/sand protection; all of this from the tires. Some sort of fender flare at both wheelwells? Maybe a formed metal cap for a few inches and/or along lower cut edge.
The front end doesn't move too much in comparison to RR axle up & down. Might also consider an angle cut to accommodate this; RR to FF. I imagine you could use a load of gravel. Shovel it out until at RR axle rating.
BRISTLES, fellas, ain't no
brissels out there . . but, then, I can't speak for FORD.
One or another of us is going to need to measure the air flow delta across the heat exchangers at some point with these aero changes (blocks, dams, pans, skirts, etc).
