So question on the air dam. Will this force air to the radiator as well as create down force in the nose? I saw this was also used by some on Dart as the V shape is a good match.
As far as I know the main idea behind an air dam is to reduce the amount of turbulence under the car by moving the air around the car instead of under. It's not necessarily pushing the nose down, but it prevents the air under the car to push it upwards.
