I don't know this for sure but it seems like it would leave a cleaner wake.

It might - unless you have an ( flexible ) airdam that hugs the ground.
Have you ever seen the underside of a NASCAR racer ? Just below the bumper is a huge cavity.
I thought that my car had a "parachute", but it is not even close to how bad that the underside of a NACAR racer is.
( We had one come to work one day. I asked the crew chief what the drag coefficient on the car was. He gave me a blank stare.)

Apparently, if you can hug the ground low enough with an air dam, no airflow reaches the back.
( These guys spend hundreds of thousands of dollars in the wind tunnel, so apparently the underside of the car isn't a problem.
