I understand the purpose of the airdam, but why not lift a vehicle with a suspension modification to increase ground clearance? With a belly pan it might be easier to slide through the air than to move all the air over the top of a vehicle. Given enough room under a vehicle it would slide through the air more like a v shaped plow than pushing all the air over. With the increased ground clearance and the higher pressure under the vehicle the downforce would also be negated, putting less load on the tires. Granted more of the tire would show but that could be negligible if the bottom of the car could be cleaned up enough to allow smooth airflow.
