So now I have this crazy idea fer an adjustable air dam. Something that I can pivot down fer highway speeds but allow it to bump up when it comes to obstacles. I might use another noodle fer the test material but eventually move on to something longer and durable.  |
I did something similar to that in my coroplast grill block :

However, I have since removed the grill block and have a two-piece spring mounted air dam.
Benefits :
- Robust failure. If the air-dam hits something, the zip-tie that connects the air-dam to the spring breaks and the air-dam just swings back. Replace the zip-tie and I'm off and running.
- No maintenance. Other than zip-tie replacement, it's set it and forget it.
Problems :
- A jack of one trade solution. For every spring there is an MPH where the spring will hold the air-dam at a vertical position in relation to the air stream. At lower MPH it will be angled into the air-stream. This might not be bad, but it would allow more air under the car. At a higher MPH it will be angled in the same directon as the air stream. Soooooo, you need to find the perfect spring for your needs.
- Stability of air-dam. Others have told me that my grill-block would be too unstable. When I did my video, you can see that it does wobble, but the "average" relationship to the air stream is stable. If you are in steady-state MPH, the grill-block maintains the same relationship to the air stream. With that said, I have seen the air-dam become more unstable when I am following a big truck because the air stream is turbulent.
