Perhaps I am being picky about terms but I would like to see some consensus on what we are calling spats and what we are calling skirts. I was under the impression that spats are the little plastic rectangles that most car makers are using in front of the tires, like the white spats we wore to cover the front of our black shoes in marching band (or the massive ones on the green Jetta).
In the 50s, fender skirts came down over the top of the rear tire. In the 90s we got side skirts that lowered the rocker panels between the front and rear tires.
OP- I think you will have to go full Basjoos on this to significantly decrease your Cd. I have found air dams all get ripped off sooner or later. I am using a full belly pan with diffuser, inner and outer side skirts and small spats in front of the tires. All have stayed on winter and summer and have greatly increased coasting distances and mpg in my experience. A full boat tail is too hard to live with day to day for me and has not been done yet on my car.
