Brake Duct options?

[kosoku]

I've seen the APR option, looks great and I'm sure fits great.

Has anyone used the factory damn and cut out in between the "honeycomb" and made something themselves?

Buy the foglight bezels and there youll have a hole already to plug in the duct hoses

Bezels are dirt cheap around $12 bucks each.

I think the issue is the big washer fluid tank. This is exactly why I want to get the TMG washer fluid tank.

My concern w/ the APR duct kit is the position of the air outlet. A lot of research seems to indicate cooling the back of the rotor surface rather than the central hub area of on top where the vanes are is less than ideal and could even hurt the rotor by causing uneven temps between front and back possibly leading to cracks or warping. Even talked about this w/ JRitt from Essex and we both agreed it's no easy application to deal with due to the limited amount of space on the back plate, so can't really blame APR for trying. What needs to happen is the hose needs to angle better toward the hub to reshape airflow so the central vortex can better evenly distribute cooler air.

The best solution for the 86 I've seen is the Essex Endurance bracket. Sadly, nothing is or likely will be available for the Sprint kit though I understand the reason why.

I have the APR solution installed and I do want to drop two notes on the system.

1.) The silicon hosing that APR ships with the rotor backing plate is a little too large in diameter. I ran with 245/40/17 tires on 17x9 +45 offset wheels and the hosing got eaten up from tire rubbing. @robispec is running smaller hosing and he seems to be having no issues as far as I know.

2.) As Hanakusa states, the washer bottle can be an issue on the driver's side duct. I believe APR recommends running the hosing up through the engine bay to get around it but if you're going to go FI like I am, this will not do as it may put the hosing too close to a turbo or another high heat source. I opted to just remove the washer bottle and route the hosing straight to the wheel well.

When we going to see you turbocharged?

Anyone know the brand of these ducts? I plan on getting a brz and swapping to an frs bumper and dont want to go through the trouble of wiring the fogs.

It was supposed to be next week but I decided to get ceramic coating for the header and exhaust side piping and I didn't realize it takes a couple weeks to get it done T_T So now the turbo is slated to go on at the end of Sept!

I did exactly that. Used a dremel tool and an Xacto knife to cut out the plastic inside the honeycomb. Not perfect, but looked great from 2 feet away.

I then used the dremel to cut slots in the plastic inner fender to channel air to the backside of the wheel. It isn't as effective as brake ducting using a hose and backing plate, but it does provide more airflow than stock. I had no brake fade at Sebring the last time I was there.

I don't like the APR kit for the reason that it is directing air at the back of the rotor face, and not to the center of the rotor, where it is dispersed out through the veins in the center of the rotor, cooling both sides of the rotor rather than just the back side. That's why I went the Touge Factory kit; it was the only kit that I could find that does this, which is the most efficient way to cool rotors.

Also, Touge Factory provides a way to work the hose around the washer bottle, which works nice, as you have less bends in the hose.

Here is my write-up and review with feedback from 3 track days on the kit so far:

Got any photos of the tougefactory kit to share?

Ive seen the honey comb cutout...someone did one for an oil cooler?

Anyone know where to get backing plates like the Touge Factory ones, or 2" duct flanges alone? I've got the fog bezels and hose, just need to find the backing plates and get to work!
