Paul,

   If you lower a car, what aerodynamic gains would be had? Higher
speed?

Maybe. Depending on what the bottom looks like.
You really ruin the high speed ride. Suspension travel is your friend :)

So it doesn't change anything, like the frontal area, just how much air
is passing under the car?

I guess what I'm trying to ask is, all else being equal, what effect
does lowering have on aerodynamics? Speeds are under 150 mph. This is a
Focus ZX3 afterall...it looks like a blasted egg on wheels. :)
Suspenders are H & R adjustable coil-overs...plenty of travel.

Most of the time it decreases drag.
Travel is ultimately a function of ground clearance. 
What are we trying to do here? Better MPG at 80 MPH?
