For the wheel skirts on my SW2, I saw between a 1.3% to 4% gain :

Because I am conservative in my estimates, I only claim a 1.3+% gain.

I have a big advantage because most of my connecting parts are plastic. I can drill into pieces of my car very easily, and I don't have to worry about rust. My personal rule is to have "reversible" mods, so the holes I drill are not where you can easily see them.

I have been thinking that my mod is probably better as "infrastructure". If you look at the picture above, you could cut out the center and use the surrounding "frame" as a base to attach varying skirt designs :

(the dots would be fastener locations)

The cool part is that the skirts could be attached with "quick release" connectors like dzus fasteners. You would have full access to the tire and you could more easily try different wheel skirt designs.
