Here’s the inside of the original front bumper. The bottom edge connects the radiator support, so you can see that there’s decent length to design a bit of duct work. The upper grille is rather high, and could be moved lower or fully blocked off.
Here’s me thinking out loud. Lengthening the front of the car could help balance out the look of a longer rear end. It could reduce pressure at the front of the car. It could allow for longer ductwork; in turn allowing for an even smaller grille opening.
Emphasis on *could*. It could also put more air over the windshield, or create excess downforce up front. Have to see what happens for myself.
