OK coding gurus, not sure if this has been done or if it is even possible but I would like to have a look at having my sedan framed door windows roll down the 1/2" when opening the doors and roll back up upon door close. The coupes and convertibles that have frameless doors and is a basic function to avoid the glass being in/out of the lip of the seal when opening and closing the doors. I guess I am looking for the pressure advantage in the sedan since the windows are not subject to the seal displacement. Just a thought if this can happen. Thanks guys, I always get the real story here.
