That doesn't seem like it would have much drag, does it?

cant post images... need 2 more posts

The link states that the rear bumper is where the flow is disrupted, and that causes the lift and severe drag as well.
I know that this picture shows aero extreme for the purpose of downforce, but there are some cues that could be taken from it to lesson the amount of drag.

1. Behind the front wheels you could extend the humb and square it off, venting the wheel wells to reduce drag in the wheel area, and increase cooling and diminish drag from underneath.

2. Extend the rear humps and square off the rear while extending a deck lid from the bottom of the window. Vent rear wheel wells in the process and diffuse the rear.
