A 135i rotor would be 5mm smaller in radius to an E90 335i rotor. Wouldn't that put the pad off the edge of the rotor? I've gone with the 2-piece Z4 35is 348mm rotor.

Yes, I would assume it's new parameters for ABS and stability control programs.
I'm not sure what you mean with your comparison of rotor sizes. If you're using E90 335i front calipers, then you use 335i front rotors. The 135i stock rotors are paired with 135i specific 6 piston calipers and pads that fit those rotors.
