I recently fabbed up some brake ducts for my '91 Turbo after experiencing brake fade at the track. I tried to make them look like they belong on the car, while making them as functional as possible. As you can see from the pics below- they feed from the stock fog light location, through the fender, and into a modified backing plate. This gets the cool air directly into the center of the rotor.
Since I put them in, I've had no fade problems at all!
I used 3" high temp silicone ducting from Racer Parts Wholesale: Thermoid High-Temp Ducting - 600 Degree Aircraft Silicone Ducting
An 11' section was enough to get it done, with a little left over.
My car had factory fogs- they needed to come out permanently for this to work.
Start by removing the underbody panels that attach to the front lip. Then remove the plastic panel that was behind the fog lamp.
Plastic shroud panel behind the fog light.
Remove it from behind the bumper. There are two plastic "rivets" holding it in place. One's visible from the front, the other's hidden underneath.
I picked up some 3" to 4" duct adapters at Lowe's.
Cut down the 4" side, so that it's almost flush.
Put the adapter in the upper outside corner, and use a sharpie to outline the inlet.
