If I had an Insight:

- Rear wiper delete. (If I'm not mistaken, the CRX had a Cd .01 difference with the wiper on vs. off.)

- The passenger mirror delete will help a little as well, with more attentiveness and a large convex replacement on the inside to regain most of the lost functionality.

- partial grille block

- investigate additional under-car panelling

More involved/radical:

- Phil's right in that the biggest gains are to be had at the back of the car. But extending and continuing the taper of the existing body lines is no small task.

- Front wheel skirts, a la Aerocivic.
