Sorry for the confusion. What i meant was for any street driving, it could be made to work.
I also wonder about removing the door handles and adding ones like drag cars now that the vent windows are gone. Top of door at the vent windows area I wonder what a 4-5" hole in the window would do aero wise in that area??? Could it still net a gain over the stock door handles?
Interesting thought about the door handles. An open hole has to present some kind of drag, the question is more or less than a door handle on the outside of the bodywork. I’m sure someone in that world has tested both in a wind tunnel.
