so, maybe the best solution in this case is something like a box cavity. but with some airducts to reduce the low pressure "bubble" at the rear.
my plan, direct the cooling-air from the engine in ducts through the car and insight the box. this should increase the pressure in the rear.
so this should maybe reduce drag

i know thats kind of stupid, but maybe it works.

what are your thoughts about that.
With the ducting,there is a risk that air will actually flow from rear to front,as the air attempts to get to the low pressure near the A-pillars and windshield header area.
If you can gain entry to the trunk through the back seat,then,by raising and blocking the trunklid open,you should be able to determine which way the air goes while driving.If the air moves forward,it will do the same with the ductwork and box cavity.
