Jeremiah 29:11,
You bring up an excellent point! The form vs function and the blend that pleases the masses most. The T/A which looks like it's part of the body while adding some downforce and is very pleasing to the eye. If you want a little more downforce without adding more drag then the wing is the better choice. By lifting it up you get away from the turbulance the body can create and into cleaner airflow. The same reason the wing cars went so big. Looking for that laminar airflow that only clean air can provide. The same reason the T/A hood was soo much more effective than the shaker hood or most any other manufacturer because it was lifted that 1" off the body.
What I do think is funny though is that optional wing I've seen in some of the other posts looks very similar to the 1969 Trans Am, I think it might be part of the upcomming heritage package? While I have nothing against the look of that particular wing I don't think it's the right look for the Challenger. Do you know the one I'm talking about? It turns down all the way to the body on the ends.
