I want this in my life (brake duct)
 

http://mynetz.jp/bluearea/item_page.aspx?id=001704
It's actually an option on OEM Japan toyota 86 racing grade. (I have catalog)

Now you can buy it just as a part separately O.o

Ya.......... 200 buck

Picture belongs to Calen in Miyagi prefecture on minkara
Now does it work?

For testing purpose it's only installed on one side.

& Yes you can't see it unless car is jacked up or you are looking @ it from even ground level.

After spirited driving

The side with air duct is 45 celcius (113f)http://cdn.snsimg.carview.co.jp/mink...d1ef545a58.jpg

The side without is 89 celcius (192f)

:D figure it's a "cool" part to share :w00t:

:drool:

Wow, what a huge difference just that one piece makes! Great post man :)

I wonder if there is an easy way to make it yourself for a few bucks. it looks like a simple piece

I guess that this have pros of being simpler to fit (as no need to route/pass air tubes/ducts like for APR or TF ducts), but cons - easier to scrape/damage/stuff with snow due being closer to ground.

Cons also might be not as effective since it's not ducted as direct

looks like a nice simple and effective mods for non lowered cars.
If you do lower the car, I am afraid the piece may get damage very quickly.
you would probable better off installing the porsche gt3 brake ducts. they cost $30 on eBay and can be added to the control arm pretty well.

Again this is more for non lowered cars.

It's good for minimal drop. The owner of this car is on HKS hipermax GT with 1.18 inch(3cm) up front, 1.37(3.5cm) in the rear.

Fact is with front lip you cant really lower more. :p + If you have a lip, the lip will actually protect this piece you see. ;)

Another thing is that I don't think the porsche one would be as effective as this on our car, this is true direct air passage from high pressure area to low pressure area. It's not so different from putting a air duct through your fog light.

Overall i'd prefer tougefactory's ducts. They won't scrape, as they are not below bumper like these, and they won't require removing fog lights in upper toyobaru trims, like APR's will, as inlets are near rad, not behind foglight openings. And they direct air directly to disk/caliper.
There is 4th option of one guy making active brake cooling with thermal sensors and electric fan, but that sounds to me like overcomplified overkill. Yes, indeed with such even stock brake thermal capacity will be enough for heavy track use, but i'd rather invest that money to upgrade to BBK, which will bring lightweightness and cheaper wearables too.

What lip/bumper extension is that?

Brake ducting is only as effective as the pads you're running.

For street use or throwaway pads, they're fine.

Caveat emptor.

Those temps are after hard driving? In sub freezing weather I guess?

Just saying, but I see water on your wheels. If I had been driving (and braking) hard, that water would have evaporated off before I can get out of the car to take brake temps.

i'm much more interested in that splitter. do you have a link to that? or better pics?

Everyone with a 3d printer, get to work!

These might actually work for me, my TFWorks brake ducts dont fit behind the bumper anymore because of the intercooler. Thanks for the find!

.ck

Do the ducts require the use of the splitter shown, or are they meant for OEM bodywork?

Maybe rain?

These look super cool though. Would it be possible to create something like this that cools part of the engine bay?

Wheels become heat sinks for the brakes... They get hot enough water doesn't stick around for long. I suspect that the intent is to say the car wasn't being driven hard enough. :) No idea what that means for potential efficacy of this part. Too many variables unknown.

Imho no need for that. Heat soaking issues might rise more in standing traffic, but airducts will not help there.

It looks like this scoop just directs air in the direction of the rotor/caliper, but has no flex hose to direct it right to the rotor eye or caliper?

Yes. Same though as Porsche gt3 ones mentioned here. Less effective then with hose, but easier to fit without cutting anything.

I'm gonna make some. Have a few ideas and should be more effective than nothing.

Notice the tool he's using to note the temperature also wet, so could be raining while he's taking the picture.

Think the amount of skepticism is too high

The attempt to test and log is admirable but the execution is flawed - too many variables.

There's lots of things which which could account for a difference in side to side brake temperatures such as track layout, pace (how consistent braking effort is into each corner as well as overall lap time consistency) and braking style (how late and how hard you're braking into corners).

In other words it'd be really easy to brake too long and not hard enough into a few left handed corners on every lap and see similar results, for example.

To make the data a bit more empirical you'd have run at least two sessions of comparable lap times, one with ducts installed on both sides of the car and one ductless, and then compare the temp differences on both sides session to session to be at least somewhat accurate.

Others mentioned the design already and I'm also highly skeptical of the effectiveness of these types of ducts since they don't channel cold air very directly at or very close to the brake discs. Might see some difference but the usefulness would depend a whole lot on how hard you're driving and hot your brakes are getting.

They do look pretty though.

It's on OEM 86 racing off dealer lot.

Decide to ask my friend to grab one, I noticed on the site its says you need to make sure yours car is atleast 3.54 inches (9cm) off the ground for easy install & take off. The thing is only 5.5cm thick (2 inches) & is being held by 4 screw & factory clip.

Brz ground clearance is 4.9" on brz for the reference. :D

Please do a write up with some pics if possible :)

My GT3 brake ducts were $30.

I wouldn't exactly call those ducts. They're not nearly as effective as the Togue Factory bits.

So it's just to redirect air for cooling purposes?

Yes, at best. Has anyone actually measured a benefit of them?

I really like these... they appear to be OEM quality, are metal, and from the basic testing in the initial post, appear to be effective at what they're meant to do.

However, I'm having a hard time prying my wallet open to the tune of $200 + shipping from Japan for essentially two pieces of stamped steel...




EDIT: I thought I recalled reading they were stamped steel, but now I can't find that info anywhere...

The JDM 86 Race version has brake ducts. I just am trying to find the part # or just buy the car :P

Here's the site and scroll down on the left http://toyota.jp/86/customize/racing/

I'd like to see how the air exits the ducts.

Me too. It's called a brake duct so it has to have more to it. Would like to see the rest of it.

That's pretty much why I said that. I've seen plenty of things called brake ducts that don't do a damn thing to cool brakes.

I found the part numbers once. You need the brake ducts together with related brake back plates. They don't sell them if you don't have a related VIN number.

Did anyone ever find out anything on that lip or the part number on those ducts?

To answer my own question, I used google image search and translate. It's a Zele Performance front lip.

Might not be the most efficient, but these are a factory looking part that doesn't require modification. If someone gets these, or if we could put together a group purchase somehow, I would buy a pair.
