I have seen lots of pics of different kinds so I wanted do do a poll on them.

A
Tire
|/ ---outside
Front of Car

B
Tire
\/ ---outside
Front of Car


Which of the two shapes better to have in front of the tire? I was thinking A because it doesn't create higher pressure between the wheels.

I was further unsure if I should ramp it down or just have it be a wedge.

Than my last thought was behind it make a 'boat tail', /\, behind it angled up to return the air to the body.
