Anybody used the APR kit out there?

The universal backing brake cooling plates will not be as effective of a sealed rotor forcing majority of the cool air through the veins, however for the price of the components you could go this route if you have limited funds, and have some time.
3" hose will not fit unless you route the hose under the car.
I have nothing against DIY. It's always interesting to see what others come up with.
We just made a functional kit that you can install in your garage with standard tools.

Just as a reference we made this kit based off of our Time Attack car, which we played with different brake cooling methods. In our Time Attack Evo, we used a modified NASCAR carbon fiber backing plate (Covered half of the rotor - we had to cut to make fit) for our Brembo GTR Big Brake kit, which did ok on the Autobahn South course 2.0mile during our 30min test session. We did not experience any brake fade, however pad wear was not where we wanted it to be, since you have to purchase 8 pads for the front calipers alone.
Once we made a backing plate that sealed off the rotor, the temperature brake temps were reduced and best of all pad and rotor wear was noticeably better.

From what I have seen, the APR kit is ONLY the ducts for the fog lights and the tubing, not the backing plate for the hub.

THIS. The sealed backing plates makes all the difference.

Great functional product just need to make it look prettier imho

Will this fit on AP sprint bbk?

I'm pretty sure in this photo it shows a part that attaches to the brake side.

Photo is from FT-86 Speed Factory's site.

Yep, you're right. Even though that doesn't give full coverage to the rotor, I just didn't know APR has a full kit. From what I read I thought it was only just the front ducts where the foglights are, including other vendors that list the kit as only the front bumper ducts. $300 something seems very cheap for a full Carbon Fiber kit from APR including the front inlet ducts and spindle ducts...

Quote from their site:

"This unit will bolt-on to the back side of the brake rotor, a high temp hose is connected from this unit to the front bumper brake duct inlet."

Hm, interesting. I know other vendors and APR themselves list just the ONLY front ducts in the front bumper for that same price, maybe @FT-86 SpeedFactory can verify that they are selling the entire APR kit including hoses and the backing plates for the rotor for $300 something?

Also, based on the pics from APRs facebook page of the kit, the backing plates for the brake rotor just blow air on the back face of the rotor itself, and not to the center of the rotor to push through the veins in the rotor, like the Touge Factory kit does.

This kit is just for the ducts alone
No piping pt backing plate

R u getting a set?

Not unless my brake start fading

Keeping your pads cooler will extend their life. The duct's sole purpose is not to just prevent fade. Alternatively, if you need a lower MOT pad, you can run a less expensive, less aggressive pad just as effectively, lowering your long term operating cost.

PMu was great at MRLS w/o fading but like CSG Mike said, it makes brake pads more effective and lowering overall cost....im seriously considering this kit
