I completed my DIY brake duct kit this weekend and it turned out great. All in all this cost me about $70 for hose (which I had too much of), flanges, clamps, and a rivet gun because I didn't have one. Big thanks to ResIpsa for creating this thread and paving the way for those of us looking for a DIY solution for brake cooling. Mods, can we make this is a sticky?

I took some pics that I wanted to share so others can use them along with ResIpsa's. I used 2.5 inch ducting from Amazon Hose and 2.5 inch aluminum flanges from Aircraft Spruce.

This is the drivers side. You can see all it took was cutting a hole in the fender liner and routing the 2.5inch hose through the hole. We had to flatten out the hose as it ran along the inner fender liner so it wouldn't rub, but it would still flow a good amount of air. T=You can see where we zip tied it to the frame as well:

Then, we cut a circular hole in the dust shield using a hole saw and riveted the aluminum flange to the shield:

The passenger side was tough. We had to squeeze the tubing through the small area between the washer fluid tank and the radiator support. You must trim a small piece off the radiator support to allow it to fit. I didn't take a before picture unfortunately, but you can see the area that was cut in the first picture below. Then, we cut a similar hole in the fender liner like on the driver's side and flattened out the hose to avoid rubbing:

Lastly, I used a dremel to cut out the rigid portion of the vent insert things and affixed the flanges directly to the removable plastic piece. This way I wouldn't be riveting anything directly to the bumper and cutting holes in it and whatnot. You could do it any way you like, but the less permanent damage you have to do the better, I say:

All in all it was easy to complete and definitely flows air. We held a little fan up to the hose after it was all fitted up and plenty of air was travelling through it. It's hard to believe people spend $300 on a kit from Stillen for this.
