I'd say Pete was still suffering somewhat, as Ive heard a story over the weekend about forgetting to connect a brake line (left completely dangling in fresh air) and the mistake only being realised when starting the brake bleeding stage. Is that true Pete? 
Yeah, sober but tired

Stuff
Definitely more piston area than stock, and the pads are a little over twice the area of the stock ones. The new brakes feel powerful, have much more progression, build up less heat, and i haven't actually been able to induce the ABS yet since fitting the new brakes, whereas in these slippery conditions the ABS used to kick in regularly with the stock brakes, especially over manhole covers and so on.Forgot to weigh the stuff but in short:
Original front calipers weighed less, but new discs bigger and lighter so approx same overall i'd guess.
Rear setup similar, approx same weight.
So from four single piston sliding calipers to a pair of six pots and a pair of two pots.
Front discs larger diameter and drilled and grooved (already vented), rear discs comparable to originals, perhaps a little bigger (already vented).
Very hard to experience fade as the BMW has a system which compensates for brake fade by applying additional pressure for you - so if you are getting fade you can't tell at the pedal. You CAN tell by the smell though when you get out of the car.
So, no i had not experienced fade on the road but i had gotten the brakes hot and smelly without trying too hard so it's possible that they would have faded but the car had compensated.
Biggest difference though is control and feel, the new brakes give you so much more control than the old single pots.

Your local BMW dealer clearly don't have clue then.
