Interesting you should mention side skirts. I made up a side skirt setup using an aluminum fabrication and rubber conveyor belt material. It worked OK as a complement to my air dam. I took it off for the winter. Eventually the snow will melt or so they tell me.

Word of advice. Don’t get too greedy on how close to the road you get. My side skirts were three inches above grade and they dragged some., eventually ripping the rubber. Maybe 4.5 or 5 inches would be more practical, but that far up may be losing the desired effect. I’m thinking about re-using the structure to support strakes.
