Alright I may have come up with a much simpler idea for the brake ducts.

So this method would be a relatively simple design, except for the inlet component. The benefit of this design is it will avoid needing to remove the bumper/ cut holes in the side of the plastic wall behind the bumper, and it would have a more direct air path. It would however require a cutout of the plastic grill on the part where that middle fin is, which could possibly look a bit strange if that fin is broken into sections around the air ducts. I suppose we don't necessarily need to cut into the grill at all, and just mount the duct behind it (will not have cool looking ducts tho). And lastly I'll have to figure out a material to make it out of, which currently I am leaning towards 3D printing for simplicity, cost, and weight. We can also use flexible brake duct tubing in-between the inlet/ outlet components to save on weight as well. Let me know what you guys think!
