oil pan 4, after going through the list of aero mods you guys have on the forum, I've come up with a solution that may be the optimum for ecomodding.

--> Front air dam to move the air around the car
--> Underbody that slopes upward for the airfoil shape in the back
--> Kammback extension to match the airfoil shape from the underbody

Important about this design is where the air starts to move under the car to make proper use of the underbody. The air dam will greatly reduce the amount of air entering the bottom of the car from the front. This will create a low pressure under the car. By leaving the sides of the car open, air will rush in under the car from the sides. Controlling where this air enters is vital, because if you cover too much flat area, you won't get much benefit. If you can get the air to enter right before the beginning of the curve of the airfoil profile, I believe you could achieve massive gains.

Not to mention the front air dam will reduce the drag caused by the front tires, and help the airflow around the car.

I have some drawings of this, but don't have access to a scanner right now.
