If the car is flat under, the air cant get a hold on the car and it will travel a lot faster on the underside of the car, and that will in its turn create a sucktion under the car forcing it down, an that gives you extra downforce, the car should also be a little higher in the back then in the front, so less air can come in under it from the front and the air that does come in under it have a bigger hole in the rear to get out thrue, to there aint any problems for the air to get out.
