Done a bit of research on aerodynamics and spoke to a freind who is versed in aero engineering. Heres what my conclusion is.
The air travelling under the car is of less importance than the air travelling over the car. Aparrently the lift created is a dependant on ratio of air over both top and underneath.
The airstream running over the top of the bug is uninterrupted right through to the rear valance. Creating LOW pressure at the rear and therefore high amounts of lift on the rear axle.
So the airstream needs to be interrupted somehow. Some kind of spoiler continuous with the bodywork (so no air can travel around or underneath)at the rear. Like a spoilerlip on the audi tt but above the rear window.
And air needs to travel faster under the car to help neutralise the low pressure at the rear. Flat belly pans/undertrays to smooth underneath and sideskirts as low as possible to maintain air travel direction.
