Lots more goes into brake noise than just the names on the various components involved. Exact pad compound might be #1. Rotor vibration characteristics - probably involving structural damping the way this TSB appears to be handling it (with high-carbon rotors) - also matters. Somebody ought to check to see if there are any differences in vane count/orientation and other rotor dimensions, as those things will affect vibration behavior as well..
The closer your pad formulation gets to an all-out track compound, the more likely it is that you'll get some noise during low-energy stops along with the improved braking performance under repeated heavy braking. So there's a degree of noise sensitivity based on how hard the pads are being squeezed against the rotors. I keep reading here where at least the SS/1LE pads seem to be at least adequate up to light track duty, so I'm not particularly surprised here.
