    They stopped making them back in 09, so they are fairly affordable nowadays and rare.

    You can get a well spec'ed 01/09 with 26k km for 60k€, that's not bad for a car like that.

    the difference in unsprung weight is negligable between floating and non...
    the volume of the hubs are similar, plus plenty of holes, and the density of the alloy vs steel is minor
    in fact many floaters use steel hubs/hats

    what impacts weight is the cross drilling (and augments cooling)

    the floating action is designed to absorb warpage, not because of the coefficient of expansion
    even if the hub were aluminum and the rotor steel, and were fixed, not floating, the rotor would 'cone', since it's on pins and it can't expand radially
    the exact same thing if bother were steel and fixed

    most composite brakes only allow axial run play, not radial, BMW is unusual in this respect, I'm guessing the sliding calipers have something to do with it (and for their use BMW was criticized for years), some do it at an angle, but either way, 1000'ths of an inch

    BMW rotors, cross drilled should not be turned for 2 reasons (other than the manual says not to) the holes and the floating function
    even if they are within spec thickness wise they say not to turn them, I'm gussing they are as thick as any others, most aset up for 1 mm wear

    I hate the C class. I hate the C class very much right now as I have to drop off my nice comfy, roomy GL for service tomorrow and will get a shitty, tiny, cramped C class loaner. :(

    I have to agree, and I have an unhealthy fascination with V-12s. Unhealthy, I tell you. But, holy hell, 1000+ lb-ft of torque? 1st gear must be pretty useless. I think this may be getting into stupid territory.
    I'm not sure what this looks like. I'm not sure if I like what I think it looks like. But it is damned cool.

    Aluminum is 3x less dense than iron. The weight difference is not negligible. A Brembo 2-piece direct OEM replacement for a 1-piece Porsche 996 GT3 rotor saves 15 lbs (31 -> 16, half the weight). The PCCB setup saves a bit more (20 lbs).

    No cross-drilled rotors should be turned, but my point is that regular solid BMW rotors shouldn't be turned either because they are very thin already.

    I can appreciate all the tech and the massive power in the F12, but having only seen the pics this week, I find it kind of ugly. That might change, the 458 turns out to be much better in real life, the FF not so much. The Aventador, on the other hand, is amazing to behold, in pics and in real life.

    The Aventador J looks better in real life pics.

    I love the Aventador, but for a completely open cockpit car, the SLR Stirling Moss was better IMO. I've seen one in person, it was like a 700hp silver phallus on wheels - which is basically what good cars are.
