I know only the center section swings up, so you would have to fill the gap that is formed on the sides when you open the hatch glass.
( This would also keep you from getting carbon monoxide in the car during testing ! )
I'd love the see the before and after results of a tuft test of the car ( hatch closed and propped open at the correct aero angle.

That is a great idea just to test the idea. I had thought about using it as part of the tail, but not to use it to see if it would help. Thank. I think I will try it today.
