That's very interesting. Why do you think so many have both undertrays and airdams? I would love to see more of the photos. I have long needed to do more under the car, but I dislike the extra access difficulties an undertray creates.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
