This might better show it.
How about your contribution?

When I read up on that active airdam, it read as if it only moved with the height of the vehicle. Since it would lower at higher speeds, it would adjust then, or drop lower when it slowed down. I didn't understand the correlation. Also, it seems like these Are showing the strakes rather than an airdam.

If only there was a way to look and see if the air dam is folding over.

Using a camera recording video would work. A lead car with a dedicated person shooting video would probably be best or a mounted camera off the nose would work just as well. 
One could calculate the results just as easily using math formulas based on the dimensions and specifications of the material as well as the speed of the vehicle, too! But shooting video and posting it would allow others to actually "see" what's going on.

The Probe-IV would lower in the front,raise in the rear,and deploy the air dam to achieve the lowest drag.
When on the open road it's ground clearance defies all SAE standards for approach,breakover,and departure angles and would be impossible to live with in town without the 'active' capabilities.
I have the image of the car in it's 'highway' mode here and am waiting to see if Al can scan it for me.He closes at 5:30.

Probe IV advanced the state of aerodynamic art at Ford to a new level, going to great lengths to make its surfaces as smooth as possible and present the minimum frontal area. A low ride height minimized undercar airflow and the Probe IV went to the extent of creating a speed sensitive ride height and attitude system. Probe IV could assume a pronounced nose-down attitude at speed. In fact, the back of Probe IV could rise six inches while at the same time the nose dropped four inches at high speed, improving its stability and air penetration. The front air dam was also electrically controlled, compensating for attitude changes and driver controllable to compensate for rough surfaces.

Porsche incorporated an active air dam for its new Turbo S model. It utilizes the air dam to reduce drag and to generate down force in different configurations.

The Porsche Turbo S likely has a very smooth underside, so it does not decrease drag fully extended. It does reduce drag by directing air around the front wheel, however. I think these facts reinforce of the superiority of a smooth under body for low drag and the usefulness of wheel strakes.

How about a mirror on a stick?
What's the point of putting a picture on Internet if you can't hot-link it? Anyway, go to https://www.flickr.com/photos/kelvin...n/photostream/ and have a look.
