While it should improve handling at high speed, the REAL
reason for the dam is not for handling, but for the improved
fuel efficiency.  What you would think is a lot of increased
drag is actually reduced overall drag because of the
reduction of airflow over the dirtiest part of the car --
the undercarriage.  That's why virtually every car made now
has big body parts hanging below the bumper line.  You can
attribute it to the CAFE rules.

I remember Car & Driver in '73 or so put a homemade aluminum
airdam on a Pinto, put clear plastic headlight covers over
the recessed headlight bucket, and wound up with a
noticeable mileage improvement.
