I put some side skirts on today. They are just a bar that runs along the side held by two diagonals from the frame. If I high-center, it will bend easily without hurting anything. I should be able to bend it back.
The pic didn't turn out very well (too dark, too lazy to get more light) but you get the idea
The coastdown tests did not show improvement, oddly enough. I lost 9 mph in the first 10 seconds instead of the 6 from last night. I did not record the temperatures yesterday/tonight, so I am sure that is the problem. Or not. Whatcha think?
