Does this have a yet to be installed back window? I would think the airflow would rather turbulent without a window, and decrease efficiency of the spoiler requiring it to be much higher to be useful and therefore greater drag. What speeds are talking? That will definitely be a point of turbulent air. I would have sealed that up well before worrying about a spoiler. But that's just my 2cents...the spoiler looks like good handy-work though! we get dinged for Lexan/plastic $X per cubic inches/feet. We are close to the $500 limit now. Once we see how much room we have after our mods are added up. We should have room for the rear hatch. Hmm, I would try to get something on there. May be work some Tuft testing to see how bad you want it, it'll at least give you some sort of feedback on what's going on back there.

Wrap a piece of sheet metal around it and fire up the mig.
Rearward vision is highly overrated.

Rearward vision is highly overrated. We get hit for sheet metal too. It's funny that you say rearward vision is over rated, my team mate yelled at me on the radio to stop looking in the rear view mirror and worry about what was in front of me.

When you get the size figured out, layup some carbon fiber, it will be way less weight and mucho stiffer. Tim

you could make it tunable with turn down flaps, or just saw-zall away.
it looks like you have a piano hinge at the bottom, you could use turn buckles on the same side to adjust the height/angle rather than have fixed mounts.
also what kind of speeds are we talking about?

Fab up a set of rear window louvers. It might help straighten out some of the air flow through the car and onto your spoiler.
Throw the judges for a loop and use papier mache.
