Is 2223 the OEM for non Msport 335i?

Yes, the 2223 is the 13.4" non-M-sport front rotor. Not slotted.

7606 is the 14.6" for the 335i M-sport. It is non-slotted, just as the above part, and both are referenced in the diagram as 01. This is the front rotor on your car.

7602 is the 13.4" slotted M-Performance brake rotor. This part can be use as either the 335i rear Performance rotor, or the 328i front M-Performance rotor. Not sure why the catalog leads us here, grouped with 335i "front" rotors. But realoem is not infallible. It is referenced as 02 on the diagram, pointing out its slotted/dimpled design. Note that the rotors are not to scale.

This is the 14.6" front rotor for just the M-performance brake kit. Notice this part and 7602 specifically mention "Original BMW Accessories" because in the US, they are not factory-fitted parts, rather dealer/VPC accessories.

Is it 7606 that shows no size?

Yes, the 7606.

7602 is only designed for the rear 335i M-performance rotor.

Correct, except for M-sport.

The question is, do Msport F30's get the "M sport/M performance" brakes as OEM/standard, not as option.

M-sport = larger rotors for both 328i and 335i. Calipers are the same as M-performance, but only available as gray (are blue in other countries). Pads are the same, I believe. The $3K M-performance option only gets you slotted/dimpled rotors, and a different color caliper.

Correct.
