Trans Am build thread

I decided I should start a new thread for any further mods I do on my car instead of posting to my intro thread.
A little background, I typically get 18.5~19 mpg. 20.5-21 mpg if I really, really tried. After sealing up gaps at the front of the car, and extending the front air dam, it's up to 21.7 and 21.5 without too much effort. My next mod was side skirts.

Anyway, I have a couple of pictures to post of the rain gutter side skirts I finished last night.







They started out white, but a can and a half of black plasti-dip fixed that. I also made up an inner pair of skirts to go up to the inside edges of the tires, but I don't have any way to mount those yet.

All told, I have less than $25 in them. When I installed them last night I had about 220 miles on the current tank. After today's commute to work and back there are 265 miles on the tank. Probably will see no difference until I have a full tank with these on here.
