Hmm. I'll have to ask that

Hmm. I'll have to ask that to Phil Knox. He did both, so I'm sure there was a reason for it. I figure that even with a dam, airflow will still go underneath the vehicle, and projections/rough surfaces could still generate turbulence.

For the looks department though, I rather dislike air dams. If I were to choose one or the other, I'd choiose a bellypan.

The benefit of the airdam howevr is that by restricting the airflow underneath, sideskirts can also have a benefit, adding to the reduction.

A further advantage of air dam/side skirts is not only reduced drag, but increased downforce for high speed stability. Usually, downforce and drag reduction are mutually exclusive!(notice that Formula 1 cars have a Cd around 0.8!)

haha, I'm going to try to round my air dam as much as possible tommorow. Did you ever ask Phil why he did the dam and the underbelly?
