Rear trailing arm - M vs non-M

Hi All, I've been digging around to understand what the difference is between these parts, with not much luck. Yes I know the bushings are different. I am asking what the difference is between the M vs non-M trailing arms themselves:

E46 non-M arms: (33326774779 and 33326774780)

E46 M3 arms: (33322229685 and 33322229686)

And bonus points if you know the distinction to the Z4M trailing arms, which are yet another part number:
E86 Z4M (33327837507 and 33327837508)

Thanks,

Filippo
