You bring up a great point about the rain guards, they do almost absolutely add drag; the glue is failing at the rear of the passenger rear piece and as I drive at speeds above 40 the guard is pulled away from the door by like 4”...

I literally just talked to my wife about modding them, my plan is to cut the rear ones just behind where they pass over the fixed window to prevent the pocket at the very back from forming, and I also wanna fill the gap between them (between the two doors) with coroplast...

Will all this help? Likely not by a huge amount, but I’m running out of low hanging fruit so I’ll take what I can get lol
