Did you ever figure out your pulsation?

With my OEM 2G wheels, the backsides corrode so much that if I remove the wheel, and it goes on a different way, there is a vibration/pulsation from the front.

Are you sure the surface where the rotor sits was clean, free of rust, etc? (they pretty much always need to be cleaned)

I forgot what kind of rotor you used, but once and awhile a defective part makes it way on to a car. Bad machining/cheap casting/bad runout/etc.
