So, after lurking around some of the various threads here in the aerodynamics section, i think i can see clear to do a few things.

1) Smooth wheel covers.
2) Extend the air dam lower. There's actually a nice lip on the front of bumper my car i should be able to straight up bolt on a 5" wide strip of plastic. It's back a bit, and will be out of sight to!
3) Cover one of the grills. I'm thinking blocking the lower side grills would be easiest then, if temps remain ok, perhaps block the upper grill, leaving the lower center opening to provide cooling.
