Update: Air dam with an air dam!

I'm finally back from vacation and have gotten some much needed work done to the ZX2!

In my talk with Tygen1 yesterday, we got on the topic of aerodynamics and their effect on lean burn operation. We discussed what we had, and I mentioned that I removed my air dam in favor of a belly pan and to decrease my frontal area. He came back with a lightbulb: The air dam does a great job at keeping air away from the front wheels and wheel well. Coupling his advice and expertise with the recent results of Daox's air dam, I decided to put it back on!



Still has the old duct tape residue on there!

The front had a problem with bending in over time, so I got pieces of aluminum bar and drilled them in behind the dam and in front of the bumper.



I was not satisfied, however. The tires seem to be too unprotected. The air dam was just too short for me and my aero crazy self! So I would like to present:

The Lawn Edging Body Kit!





Now, THAT is low enough! There is about an inch and a half of clearance around the outside. I did not have time to test it out though, but I am going on a long drive in the morning in which the route is one I know quite well. I will update what I find out. There should be a noticeable difference, with a majority of the air that would be affected by the tire is being diverted. Well, I'll know soon enough

I do plan on coastdown testing when I get my MX3 wheels and smooth covers put back on. I'm hoping to best a Prius's 0.26 Cd
