Forgive me if I don't see a huge difference in the overall. I see a tiny bit more yellow hitting the rear spoiler, but not much.

Would it help to bevel the leading edge of the roof wing (down) as I did in real life?

I think it's 3/16" thick.

The rear spoiler is 45 degrees or greater.

7" to 8" gap under the front chin spoiler.

I can tell you that there are depression wells in the bed cover fabric while at speed, mostly between the last spar and tailgate but some in the middle one too.

I'd really like to see those corner vortex's forming. That is my next modification, to tame those suckers.
