Having a new 435 with M Performance Packs I & II like you have, and having a 2007 E92 for 7 years, I can say that following BMW's recommendation made for a car that has never burned oil to the point that it had to be added between changes.. I'm doing the same for the 435, which by butt dyno, has measurably more grunt than advertised, even below 4000 rpm. You'll be hard pressed to keep out of trouble even following their recommendations.. no need to beat it at all during break in. You'll see that you can pretty much bury the marker on the torque scale (goes to 400 ft-lbs) even being nice..
The Brakes will seat without much fanfare. Just don't be too hard / lock them up for the first 100km or so.
