And yes, I know that my dust boots burnt away years ago...
Here is the passenger side brake duct I fabricated. It is functional as is but could use a little finishing. You may notice that the duct on the driver side is slightly different because it is made from carbon fiber and required less bracing.
My new intakes are directly below the fang vents and are also made of fiberglass and resin. Currently they are pretty rough but I will be finishing them off later.
Just in case you are wondering, those top ducts act as cold air intakes, the rectangle cut below the grill is additional air into the oil cooler, the plate covering the grill is to prevent air from getting to my oil cooler when off the track, and the two large rectangles are additional radiator cooling.
