Also seems that Brembo is an OE supplier to BMW, at least for the 4.6is model. I ordered Brembo rotors from AutohausAZ for $97 each that carried the same PN as the BMW OE - 34 11 6 756 847

They came in a BMW Group original parts box with the same PN listed - no Brembo shown anywhere on the box.

That's a pretty good deal for an OE rotor for the IS model, since normally best pricing you can find for those is $150 or more.

So with Textar pads, which is also an OE source to BMW, I paid $270 for my complete front brake job. Plus another $20 for the sensor that doesn't seem to be working.
