Custom rear spoiler for the Missile

The effects a wing has on a car can only be determined by actual testing. All cars have different aerodynamic properties. More modern cars all tend to have the general "semi-teardrop" shape, so their aerodynamic properties are very similar.

When Chrysler wind tunnel tested the Superbird and Daytona Charger, they went through many wing, nose, and air dam configurations. The wing they ended up using began to provide downforce only at about 60 m.p.h. and the AOA was adjustable. However, the greatest secret of the wing assembly was the lateral directional stability it provided at speed. Everybody else concentrated on the wing itself and not on the vertical stabilizers.

I can't wait to see your results, Andrew.
