While it's not the same as directing air directly to the rotor, I'd put money on it being beneficial with real world significance in temp reduction. The only change I would suggest is to have the cutout positioned higher in the wheel well. The current location is very low and may just have the fresh air sucked down by the low pressure under the car. Perhaps positioning the hole up closer to where that pop rivet holds the liner and then downsizing the tubing to 2" with a further run and turn toward the rotor could improve the design (think 2" PVC from the wheel liner with an elbow rather than flexible ducting). This would give a 'ram air' effect and help direct the air toward the rotor. Just have to downsize enough so the wheel doesn't rub on the pipe.
This won't stop Ice Mode from happening. It WILL reduce brake fade and hopefully stop the dust boots from disintegrating!

Spearfish,
I thought about giving it a better angle to the rotor plates but chassis & suspension part couldn’t allow drilling on the upper part of the wheel well. If you have any DYI on please let me know since this suggestion was to build a simple cooling mod.
Regarding PVC, I’ve spent a couple of hours trying to make a PCV ducking but i couldn’t make it work properly and allowing enough flexibility for chassis movement (turn in, braking, accel...). For me, high heat resistent tubing was more convenient and user friendly.
Also, regarding the fact that colder air will not reduce Ice mode, could you be more specific? I am running DOT4 brake & clutch fluids and Stoptech pads on all corners and do not have any brake fade.
Pls advice,
regards Phil
