They were pioneered on the E34 M5 3.8 of '95 --the first road car in the world to have floating rotors.

In Europe, only the 3.2 Evolutions have them, as they were introduced to the M3 in the 96 MY. '93-95 3.0 liter cars do NOT have them from the factory, AFAIK.

From what I have read, they can shear off the hub once they wear down. --I mean wwwaaaay down. With a conventional design, the rotor surface weakens and warp, but never come off the hub.

BMW NA's lawyers were worried that a high-milage car whose owner is too lazy or cheap to replace a set of baddly worn rotors risk a total and catastrophic failure.

Which --in this lawsuit happy country-- I can see. Remember the suddenly, unintentional acceleration lawsuits in the 80s? Audi is only now begining its recovery in the US over that absurdity.
