The positioning just determines WHERE it is distributed. If you need more steering- move it forward. If you need less steering (more rear bite) move it back. You can also play with the rear spoiler as well to suit your needs.
Most guys I know have about 10- 12mm overhang (bumper to body) in the front. The rear wheel cutouts are pretty much right on the money, but the fronts depend on if you run the short or long wheelbase. I put the wheelbase in both short and long with a new set of freshly trued tires to make sure the front tires clear in both positions.
