DIY brake cooling duct
 

I frequently visit 370Z forums for help with my 09 Infiniti G37S. Due to similarities with 370Z most often I get better help from the Z community. So just want to share some pictures of the brake cooling duct I fabricated on my G. Just thought might be of some use for the Z community as well.

Fabricated using 6xxx series aluminum sheet. 0.035" thickness. 0.035" thick aluminum came closest to the original thickness of our splash shields, which by the way G37S and 370Z Sport models shares exact same part.

Made the hole closest possible to the center of the hub. So that vented air won't blow on rotor face. Tilted the aluminum pipe 15 degrees so that it won't rub against the steering column. If the pipe sets straight up, pipe has to be positioned further away from the hub. Picture Below.

Fabricated bumper inserts to hold hoses from the front. With one opening to the cooling duct, and another for the Injen CAI.

Fitment was a little tight for the splash shield, but no major issues. Went in nicely.

Ran the hose through back of suspention, Attaching to the front bumper inserts.

About 3-4 inches to the front of where the sway bar brackets sit.
Is the closest point where tire will rub the hose.
Just enough room to lock the hose under the chassis.
Next to the sway bar bracket.

Picture below is driver side wheel,
when the steering is at fullest left hand turn lock.
Hose will get compressed.
And if the length is not appropriate will rub
against the inner corner of the wheel.

Picture below is also driver side wheel, when the steering
is at fullest right hand turn lock. Hose will get extended,
and if the length is not adjusted will push the splash shield back.

Just played around from lock to lock and to get
the length just right on both lock positions.

Duct tape over the hose and clamped tight with worm gear hose clamps.
Used the bridged ones specially made for the application.

Front of the car. Almost can not tell on the shadow part. Very stealthy.
Painted the hole thing with flat black spray paint.
