GT350 Rotor Noise

[VoodooBoss]

This was interesting. After my later sessions at Thunderhill yesterday I heard this ticking sound. I realized it was from the front rotors. The rear rotors were also making a noise and it was more like a hissing sound. I don't think anything is wrong but wanted to share so nobody is surprised by this. Has anyone else heard the ticking sound?

Its likely the hats/rings moving relative to the pins due to the mis-matched CTEs as its cooling down =)

Yep. I wonder if Audi R8's do the same thing?

Assuming the driver could put enough heat in them, I would think so.

Yeah, the R8s do the same thing. I coached a guy in one at Laguna last week...same noise.

Front rotors make the same noise on my BMW race car with two piece rotors. It is the rotor's cooling down and contracting and expanding at different rates due to aluminum hats and iron rotors.

+1 on the cooling contraction. Mine do the same thing.

Floating rotors and pins.
