I'm thinking lift from the underbody is caused by messy airflow getting stuck under the car, resulting in a decent amount of drag. If you clean it up with an undertray, and stop some of it from getting there with an airdam, you can eliminate lift and drag at the same time. I'm thinking reducing the air's influence that pushes up, instead of adding more that pushes down.

There are intersting examples of adding a spoiler, wing, diffuser, or both and actually improving the efficiency of the system. Ducktail spoilers done right can reduce the size of the wake behind the car while pushing the rear down, and spoilers and diffusers in tandem can "drive" each other. Whether or not average joe can make it work is a lot of luck and testing

But the thread is about the undertray, and I'm getting off topic
