Awesome info - thx indeed - curious where this originated as reads like it ought to be an internal or at best a dealership awareness document! Lot of very interesting info will take some time to digest

BMW University docs are technical training for service personnel update and intro classes.

This is great. The S55 / N55 comparison in the second document is very nice and will come in handy for keeping the misinformation and mud slinging in check.

Awesome thread.

The standard steel brakes are 15" front and 14.5" rear. Added to this is the fact they are 4-piston and 2-piston respectively. The F10 M5 only has single piston rears while the E9x was single piston all round and a half inch smaller both front and rear. Very much looking forward to this brake setup for my track days, finally the Porsche guys won't be laughing at how I needed to mod the stock system just to run consecutive laps.

I'm interested to know why they went with this set-up instead of the single piston in the rear.

Agreed. Lots of debate about that.

In general, the more pistons, the better, when it comes to brakes. Obviously, there is the cost of the psitons to worry about, but more pistons, means more surface contact with the pad) resulting in a greater area of contact on the pad), more mass to absorb heat, and overall better performance. Two smaller pistons might even weigh less than a single larfge piston, while still having greater contact area on the pad.
