I think you're looking at slightly the wrong thing. I think it's not the
air being exhausted out the doors, but rather the turbulence at the door
intersection with the front door jamb/ corner. What VW did on the 88's
was to COMPLETELY seal this gap flush right to the outer surface with
door gasket. I've had 6 of these and the 90 and 91 are  noticeably quieter.
