RE: Homemade Airduct Brake Kit
If I read it correct it sounds like he has the ducting pointing at the front of the rotor, not through the backing plate like the FR500C's are setup. By the way, the FR500C carbon fiberbacking plates, ducts and inlets run $1129 through FRPP in a set. lol

I just realized - did you even cut a hole in the backing plate or is the air just blowing on it?

finished product and thoughts:
Works well, even at high speed it stays attached. i took it above 125mph many times and they are still exactly in place. the hose says that it will handle 5000ft/m. I dunno if that's cubic feet or not, but assuming your going 60mph that means you are going 1 mile/minute. That means if the air is still, it should be hitting your car at 5280 feet per minute. So I'm inferring, based on this, that they are working at full capacity below 60mph. You can try bigger duct hose, but I wouldn't use more than 3.25 maybe 3.5 inches. You will have to squish it a bit, even at those dimensions.

I mean the metal plate behind the rotor - did you cut a hole in itso that the air actually gets to the rotor or is it just blowing on the plate?

ummm - yes, remove it. It's not doing much of anything right now. But I bet the backing plate stays cool LOL
You need to either remove the plate entirely and fabricate a bracket to attach the hose to or use a holesaw to cut a 3" hole in the plate and attach the hose somehow to the plate.

RE: Homemade Airduct Brake Kit
say good-bye to the plates! odd, and i swear its not just cuz i went thru all this hell and im just saying so, but this job still makes a noticeable difference even w/ the back plates.
