You reduced by 28 square inches? How do you figure this? Just by lowering the car? No way, Jose'! Seems to me you didn't change the frontal area...just lowered the total a bit! Did I miss something? Air still goes under the car...at about the same mass flow rate (velocity / compaction).
An air dam would force a portion of this air up & over...not letting the mass get "tangled up" under the cluttered undercarriage. Of course, a smooth bellypan would be best ; that's been done, too! With marginal benefits.... -TH

Frontal area was changed: a little less of the front tire treads was exposed after lowering.

Some front wheel drive cars specify TOE-OUT.
