As for the side skirts, I'd try some coast down tests to see if they have any effect. If they add to the ability to coast, I'd keep them.

agree with above
the side skirts could slightly be helping air get smoothly (or smoother) around the rear wheels, but they and probably also negatively affecting airflow after the front wheels. It could be a draw and make no difference
