Brake cooling ducts

Recommended Posts

I stole an idea from the FT86 forums of using Porsche GT3 brake cooling ducts on our cars.

It's a very cheap way of getting extra brake cooling and has been proven to lower temperatures.

The oem Porsche parts are being sold for £25 on ebay - http://www.ebay.co.uk/itm/201600599082

There is a bit of modification needed, and I'd say about 4 fairly beefy tie wraps per side to make them a secure fit.

Control arm before:

The duct as it arrives:

-Cut along the green lines with a sharp stanley knife,

-Drill the holes marked with green circles

-Attach to the control arm with tie-wraps at marked points

Pic of it attached (minus two tie-wraps on the middle loops I added later)

Didn't need to modify mine. Also, those look to be mounted differently to how I remember.

Nope didn't need to modify mine either - been on for a good 6 months plus.

I see yeah, so you've got the whole unit further from the caliper. (and drilled holes)

Good to know for anyone else fitting you need to make holes regardless of placement.

I went for getting the duct surface flush with the arm without sticky-out bits for better airflow but I can see if you want to save a bit of time that works aswell.

I didn't even drill holes, used 4 cable ties per side using the brackets own holes. It's not going to impact flow that much seeing as these are more of an air guide than air ducts. I did try and bend all plastic behind the arms as best I could though, sits flush.

Sorry to revive an old thread, but I’ve just bought a set of these from: https://www.design911.co.uk/fu/prod128126/Porsche-997-Brake-Duct-Air-Scoop-99734148392-99734148492/

Only £15 for the set and they were delivered within two days. 
 

Hopefully going to fit them in the next week but I wonder if anyone had anymore pictures of them fitted without chopping them up. Just trying to avoid removing material and placing them in the optimal position.

I trimmed them to fit round the bottle of the calliper or ball joint hard to tell in this pic can I have been to sleep many times and forgotten, also removed backing plates.

Did make a descent difference, and for the cost its a no brainer.
