BMW i3 - Low Hanging Fruit (improving aerodynamics)

I recently watched a video where it was mentioned that the cd for the i3 is rather high at 0.30. Looking for some low hanging fruit to improve upon that.

Obviously the mirrors are an easy target. One owner has already done a delete and camera retrofit to that end and it is probably going to be my first step.

I may go so far as to put fairings over the rear wheel openings as well.

That said, a boat tail per-se is out. The car already looks funky enough as it is.

Got any other suggestions likely to produce a measurable result?
