No, not from me, but Modified Mag. Coz, our vendor, posted this up. (PDF)

On the last page, there's a note of the various temperatures the rotors hit (OEM and the Akebono) for the Z after running a couple of laps at Bondurant.

 

Very impressive heat reduction. DOMO
..can't wait for my next track day

 

Interesting stuff. Those are some pretty big temp variations.

 

No doubt. You might have a hard time getting those to overheat.

 

I wonder if the 370Z has some brake ducting behind the bumper, as the temps (front) between it and the sport brake packaged 350Z were 30* different.

 

It's possible, but i don't think it does.

If anything, I think two things are coming into play here.

1) The spoke design may have something to do with it. The 370z spokes has a propeller-like design to it, it could be helping with airflow compared to the deep dish set-up of the 350 test vehicle.

2) The 350 is dropped, with barely any wheel gap. On the 370z set-up, there could be some air flowing through the wheel wells, into the inside rotors, which could help cool it down some.

These are just postulations, so take it with a grain.

Then again, they did say the brakes and tires were no longer the issues on the 350z with the upgraded suspension. Without seeing their lap times, it's entirely possible the 350z was driven harder.

 

I remember a long time ago reading about the wheels on the 370Z during the time when they were testing the car. Apparently they were designed to help cool the brakes by acting like a fan to suck air into the brakes. I can't remember where I read it though.
