Me and my engineer talked about aerodynamic features changing how they act at different speeds in great depth, but never considered anything these low speeds and it was usually boundry layer stuff not whole structures.

This is kind of important to me since I would like to make real metal side skirts for the suburban that are removeable once I cut out and replace the bondo and fiber glass around the rear wheel wells.
I was planning on installing them for road trips since most of my usual driving was at or below 55mph.
