Wdb,
The older information and older pictures of the Colorado from about six months ago (when I was seriously considering waiting for one) didn’t have the air dam on the Z71 models, just the base, work truck, and LT. Now it appears they have the air dam on all the models, probably for on road stability reasons. If you look on their website though you can still see some of the older photos up of the Z71s without them.

Sven7,
I looked long and hard about moving it to right under the front bumper cover. Since mine is rubber, it doesn't matter at all if the dam scrapes or drags, but since I actually offroad the truck a bit, I didn't want to risk dragging the aluminum subframe, since that could potentially damage the truck or puncture a tire if it came off. I could mount if more forward, but it would complicate the mounting significantly.

If I didn't offroad and want the clearance, the X-runner Tacoma has some interesting aerodynamic lower molding pieces on the front bumper, sides, and back that I would probably try to retrofit. Toyota has the 2WD Pre-Runner access cab at CD 0.394, but the 2WD X-Runner access cab at CD 0.357. So there are factory toyota bolt on fairings available that could reduce CD by 0.037. Nothing to sneeze at.
