New here, had fun perusing, now I'm down to the data questions:

Ok, so I've seen Cd data for AeroCivic and a few others, showing the extreme Cd improvements they've gotten with a full boat-tail... but does anyone have the data for 'milder' Aerodynamic modifications?

Specifically, I'm wondering if any Cd data exists for items such as:
Belly Pan
Kammback/short tails
Wheel Well Covers (rear wheel wells)
Moon Covers - wheel/hubcaps

I've seen the Belly Pan results at ~2-3% MPG in ABA testing per the Wiki article, wondering what else has been documented in terms of MPG or Cd tests.
