Julian is right that there are other improvements to make here, but that airdam is really well placed, and importantly, the further forward you place it, the more it will scrape ditches and bumps, the more it will beat into parking stops. Mine works great. I once diagnosed it must have broken loose and sagging by a drop in freeway MPG. I pulled over to check... and there it was... resecured it... MPG returned. For me it makes a big difference.

The aerodynamic reason you have an air dam as far forward as possible is that otherwise it helps develops lift.
