I just thought of some other questions I have not seen answered elsewhere.

Regarding the point of stagnation and the underbelly. Does the air under the car have a lower or higher pressure? I think it's a low pressure area but it's not obvious to me.

Is it better to have a sharply defined, upward sloping air dam parallel to the lowest points on the car or a bumper curved under the car from the stagnation point (like in the template?) the trailing edge of which terminates parallel to the lowest point under the car?

Thanks.
