two thoughts,
One the aero lay over is off center, the highest point on the car needs to match the high point of the template.
Second, after looking at the pics of the rear wheel travel areas one word comes to mind SNOW.
it looks good, but I worry that snow and ice might build up (think frozen slush) and jam up the suspension travel. thats why in mine I left the suspension open in the front and back. My first rear belly pan got snow and ice build up from this and that made it fall off
