I think I like the pics. I always thank the pics. In this case that flare in the lawn-edging is a little like mine. I do not know what if any effect it has. I also saw a decline in road noise, which I understand is a good sign for the operation of the mod. As to the tires poking out a bit beyond the air-dam. I deliberately chose that design to mimic what I found from the tire-spats tests in an article previously posted in this thread: the testers found that spats that did not cover all of the tire produced less lift and increased the effective frontal area of the car less (because they were shooting air less distance off the side of the car). I do not know if what holds for those spats holds for an air-dam. I just made a judgement. I did not test my air-dam (too busy), so I cannot back-up the claim empirically. It's just my experience. The air-dam was associated with new highs in mpg, but it was not an isolated mod (I did others simultaneously). I hope that helps. Others will offer maybe more authoritative opinions...

But I say... nice work!

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.
