If I could make something like that, but solid from the hinge seam on back.. No under-flow.
Make it rounder in the back, extended a little more in the middle.
And very thin on the trailing edge. Thin as one sheet of coroplas 
Would something like that move the separation point back a ways?
Since it seems logical that moving it back would result in a little less drag..
Or, maybe slope it downwards a little, like the beginning of a truncated boat-tail.?.
I see a lot of SUVs around these days with that sloped down look on the rear 'visor'..
I remember seeing a lot of 50s cars with a visor that look kinda like that spoiler,
only they were on the front windshield..  |
I wouldn't slope it down. If my understanding of the relavent aerodynamics is correct, you want a clean break of the air flow from the body to reduce drag. I think that's what a kammback does? Moving the separation point aft is the ideal.
A look at the typical spoiler found on the backs of Mini Coopers (a CRV on a smaller scale) shows how it probably should look:
I'd use filler to smooth the transition, but the basic idea is there. Going much beyond this, in length, may offer little improvement.
