So, your fuel economy has improved by 33% already, yet not a happy camper?

What do the tuft tests or oil streak tests show for flow around the wheels?

Next stop: Get some oval shaped rubber trash cans at WalMart, cut diagonally to make fairings for the wheels, per Hucho pic of Calibra wind tunnel and your tuft tests, to properly orient the fairings into the relative wind as seen by the wheels.

Got pizza pan aluminum wheel covers yet? I'm told these run ~$3 each.

Got smaller, more streamlined motorcycle mirrors yet, to replace the Dumbo the Elephant ears outside mirrors? ~$30 on eBay.

You've made remarkable improvements already. 20 mpg at steady highway cruise can happen, with the existing belly pan + mods noted above.
