If I drop it to the bump stops I can just go over the control arms with the cover since they will be up higher
I could cut away part of the pan where the wheels turn and leave the rest alone. That would get most of the control arm covered.
On the rear I could build basically a sealed system that gave the tread 1/8" clearance and the back side could be near form fitting and let the wheel shape it precisely for me. That could join with the wheel skirts to keep all air out of the rear wheel well.
I will get it on it's side again this week and get some pictures and try and illustrate what I have planned so you can see it better. School starts back tomorrow so I will be busy with registration and junk this week probably unless I can get out of it again
