2020-10-19 - Air Dam Angle
The rules do not currently specify a a tolerance on how "vertical" the air dam must be. Other series (e.g. NASA, SCCA) put this at 5%.
Is this currently defined for ChampCar?
There is no definition on angle. However if you have a scoop type i.e. angled air damn you will get points for both horizontal and vertical at 20 points.
