You do plan to tuft it right ?
Why not add a vertical 'spine' that meets up with the rear window? ( At the center of the car ) You could add tufts to it and get a better idea of where the airflow is going.
( Basically just a rectangular piece of coroplast / cardboard that would have one edge cut at an angle to meet up with the back window. Rather than taping the tufts, you could even poke holes in the thing and sew the yarn into it. This would keep the yarn from sticking to the tape or being affected by it )
Also, the edges of the sides look like they will cause considerable drag ( my guess ).
Any plans on taping the sides flush with the car ( at the B-pillar )
