Carry those "spats" forward on the wheel arch -- right to the leading edge then to the top of the arch - a set of wheel gurney. They would effectively create a vortex running down each side of the car. but not do much for under hood/wheel well (as I recall) but keeps air from migrating under the car.
Sounds like you've a plan coming together. I didn't realize the fans were that heavy - I'd better check mine now.
Like Pappy said, wheel rotation really throws the air forward. Somewhere I have a pic - I thought I posted on here once - from a smoke test in a wind tunnel with rolling road. Really eye-opening.
Cheers - Jim
