I want this in my life (brake duct) - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

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!

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?

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.

Gunman · 09-26-2015, 10:47 AM

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?

churchx · 09-26-2015, 11:17 AM

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

stevesnj · 09-26-2015, 11:24 AM

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.

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.

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.

Please do a write up with some pics if possible

My GT3 brake ducts were $30.
