First Problem With my 370Z

If you hadn't had the rotors replaced already, I'd say with near absolute certainty that it was just transfer turning into cementite (real word).

That said, your driving style could easily have compromised that new set immediately after installation.

I usually recommend for folks like us (I have done this to nearly every car I've ever owned, with the exception of the Z for reasons I'll explain in a sec) use a sintered, all metal pad and just deal with the extra dust and noise (shims really take care of most of that).

I've had sintered pads since almost day one (hard core race pads made by CL Brakes, RC6) and Carbotech has a couple of formulas that are suitable for daily driving as well as autocross or spirited driving.

Again, they're dusty, they make a little noise, but they feel AMAZING and aren't capable of forming cementite as they are not a material transfer pad like ceramics (stock pads) are.

My 2 cents.
