I am so surprised it is not easy to find more information on this regard. I hope this helps some of you.

Overall look of it. It clears perfect my 18" track wheels

feeds the air straight into the rotor inner fins which should cool a lot better.

No interference with moving suspension parts

Nice placement next to the air duct for the transmission cooler. I may play with this more if needed

4 clamps, 2 NACA ducts and 8 ft of flexible high temp brake duct
