I make and sell these brake cooling deflectors. They are a Porsche OEM part modified to cool the brakes of the 350Z/G35 chassis. This Drastically cools down the front brakes on this chassis. Full benefits if you remove the dust shield.
If you track your car this is a no brainer mod. They bolt directing the front lower control arm. Takes about ten minutes a side.
I cannot provide 100% accurate cooling data as it varies widely due to application. For my 07 350Z with the brembos it has dropped peak rotor temperatures on track by well over 200F. I tested this with rotor temperature paint. The paint will not give me exact numbers obviously. This is a drastic drop in temperature for a track session.
If you are running a crazy angle kit this will not work. If you are running a 12" wheel will some kind of crazy odd high offset this probably won't work either.

There is also an eBay listing if you feel more comfortable buying it there. You'll have to pay shipping.
I put way too much work and time coming up with this design and tweaking it work properly to respond to troll posts.
I will respond to actual questions. Feel free to PM me as well.
International shipping possible? (At buyers cost of course)
Yes, I will ship it overseas if you want to pay the shipping cost. I am in Chicago if you would like to look up rates from different shipping outfits and see what is the most economical. Package usually weighs 1.5 pounds and the dimensions of the boxes I put them in are around 8"x10"x6"

Fantastic, I shall check out some options and PM you.
Looks like a nice option to have, I wanted to make something myself but at this point, other commitments etc etc

Oh yeah I get it. It took me a long time to design and tweak these to optimise flow so it would work. All in between everything else I've got going on. Just a little bit at a time. Such is life.
Will this still be beneficial if dust shield isn’t removed?
Yes, you do not need to remove the dust shield for this to work. The dust shield is shaped to allow air to enter into the rotor cooling inlet on the bottom front side of the rotor. This is exactly where the deflectors send the air. The inlet is circled in the picture below.
I wonder how these would compare to the tubes?
Also how ride height would affect airflow as well. In track racing they use the tubes since at their height one of the main effects is to prevent air to be trapped in this area so a hose solves this but adds complexity and faster deterioration when compared to your deflectors.
I think I saw this on the 3D group on FB. Good ****!

A lot of teams are actually switched from the hose/duct setup to this deflector type. All that dictates flow is differential of pressure. The higher the pressure at the inlet and the lower the pressure at the outlet. How you get that pressure high does not matter.
The issue with hoses and ducts is that each 90 degree bend in a 3 inch hose effectively adds 10 feet to the hose. Each 30 degree bend adds about 6. A 120 degree bend adds nearly 20 feet of hose to the effective pressure drop. Some setup have a theoretical length of 35 or more feet! I know all this because I am a maintenance mechanic at a printing press shop. Lots of drying ink. Lots of hoses. I've learned a lot..
There is no pressure drop with a deflector. It just hit the deflectors, diverts, and whatever it hits suddenly has super high pressure.
In this case it is hitting the rotor cooling vane inlet. High pressure at the inlet. Low pressure on the outlet. Wallah! Brake cooling. It's worlds more effective than I imagine it would be. I believe that inlet is in a low pressure zone. This changes it to high pressure. I do not have another explanation for why these are so effective.
I tried sending you a message with your tracking number. It says you have too many messages stored so I can't send you anything. Delete some and I will send you your tracking #
Also, You will notice there is a stiffening tab on your brackets that is not in the pictures. I stiffened up the design just to prevent any form of metal fatigue that may or may not have occured over time. I like my parts to last and I am sure you do too.
Did you have the nismo brake ducts installed? are you planning to install this as a conjunction, I have the nismo ducts like yours but I'm considering to add this deflectors as well, pls help!!
Running 18x9.5 +15 in the front and full lock they do rub the deflectors a bit, nothing some trimming can't fix though. Excited to see how these perform!
