> New Brake Rotors Installed, What pads to use to "break in" the rotors? New or used ...

New Zimmerman front brake rotors were just installed on my 914/6 3.2 (conversion) DE car. It is using 911SC brakes front and rear with Porterfield R4 race pads.

The old rotors had developed a bad vibration and were worn beyond spec after 5 years of track use, so no chance of having them turned (again).

Should the rotors be run in with new pads or old (60%) pads.

I will be attending a DE day on friday and the new pads need to be heat cycled before the event.

I do not think it is advisable to heat cycle the new pads on brand new rotors.

Your opinions, experiences or expert advise is appreciated.

Thanks in advance.
