If you want 370mm rotors in front, those where the part numbers for the front calipers. (and the rears).
Both in blue.
As I saw in realoem.com the are superseeded by new part numbers. But your dealer can check and see the correct numbers.
As the 18" M Performance Brake Kit is only available in yellow, red, orange you shouldn't order the kit.
But you can order everything as single replacement part.
The blue calipers for the 370mm front rotor can be ordered as such replacement parts.
For example the 335i get's the 370mm rotor and the blue caliper when buying the option "S2NHA".
The following link shows the 335i front caliper part number with "S2NHA"=YES (so the calipers must come in blue)

(I did choose the 335iX USA version, because the 328i USA Version will get 340mm front rotor with the "S2NHA" option. And so the blue calipers will only fit for the 340mm rotor but not for the 370mm rotor)
For the rear caliper:
The rear rotor with the "S2NHA" option will always be 345mm size. So the same blue caliper is used for the whole F3x series with "S2NHA" option

For the front rotors: Any 370mm rotor flat surface or dimpled/slotted version is fine
For the rear rotors: 345mm rotor come in different flavors depending on the emergency brake size. So you dealer needs to order the right one for your car.
I belive
34206797607 normal flat surface
or
34206797600 dimpled/slotted surface
are those for your car.

Yes this helped a lot!
Just some quick additional questions. Based on:
http://www.realoem.com/bmw/enUS/show...diagId=34_1949
It looks like front should be 340mm for me then, and 345mm in the back?
Since I've never bothered to change rotors before, is there any difference in OEM vs aftermarket ones?
Thanks!
