Hmm...

The positioning of the calipers seems to be more of a "put it where it fits" thing than anything derived from physics. They tend to be all over the place.
However, when you're dealing with these monsters, you put 'em where they fit. My new calipers are the same as those and I had to put 'em in the same place.
The duct work pulls from a dedicated opening in the front fascia. It's got a pit of a funnel shape to prevent air from spilling out and across the front bumper.
