The m3 subframe actually has narrower axels. Its about 10mm narrower per side.
S65 itself is only 15lbs heavier than the n54 and sits further back. The transmission and associated parts are however heavier. My first car weighs 3250lbs vs my e92 at around 3650ish.
It is better to go all M3 axels. You will need all of it. The ability to run m3 brake set ups, m3 steering and full m3 suspension and LSD is a huge upgrade that changes the car as much as the motor swap.
