There really is more for you to learn from foundational research about lift and drag, but you routinely just dismiss all of it. "Replicate the relatively rough surface of a car" is not not the path to lowest drag and lift. It is the path left available by an automotive industry, regulatory regime, and consumer market that makes more "ideal shapes" not practical on the road.

EDIT: But I have to admit no interest in driving a "template" shape as my DD, even though that whole discourse has been a pathway for teaching me valuable aspects of the aerodynamics of my car. I love the shape of the 90s Hondas. My goals are also a little like yours, Julian: optimization through testing mods, tweaking, retesting.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
