Hi Neil,
Take a look at the car below...
I found this photo on AutoSpeed. Notice how the smoke plumes move across the top of the car. And see how they drop away from the trailing edge, which are shown by the two red lines, and are at 8° and 15° from horizontal.
Then take a look at the plume from the bottom of the car, as it is very flat with hardly any angle at all for several feet past the bumper. It seems to reinforce your design angle of 4° or so.
Jim.
