I’ve returned.
Im designing some better schematics for possible aero-mod/ and I’m reconsidering my decision not to use any modifications at the rear windshield area (there’s a term for the rear windshield angle, which I can’t recall). I’ve studied the area and I’m fairly certain that the biggest problem is turbulence at the B pillars, as they do not blend in nicely to rear windshield. Modifying the rear is likely to help a lot in lowering drag.

In this thread, they designed a little clear acrylic box to go behind the windshield, and smooth the airflow, as well as reduce the rake of the rear glass. I want to make my own version of this for my car. However, I want to know whether this would fog/ice up terribly. I feel like ice isn’t a big deal (my rear windshield is already a wall of ice right now), but trapped moisture could be bad. I think I might design a simple ventilation system into it.
