Most of my thoughts on aerodynamics first center around symmetric airfoils just because they are the "ideal," but you are right. Being a funky, cambered "airfoil," the ideal AoA will vary based on the specific car.

The lowest drag solution will be one where the car generates no lift (Cd,0). Ideally, I think that should be achieved by setting the car's incidence angle to zero and cancelling any lift with downforce (e.g. a venturi). Raking the car, as Tasdrouille said, increases frontal area.

In the real world, rake would probably be a more practical solution, but that Ranger seems a little excessive.
