Looking at the measurements provided

ZSP front sway: 26.5 mm 39310 mm^4

M3 front sway: 26.5 mm 39310mm^4

Are these sway bars essentially the same? What are the differences and would there be much noticeable difference between:

ZSP Front sway / M3 Rear sway
and
M3 Front and rear sway?

Thanks-

See the attached pics: M3 sway has bushing stoppers so it does not slide within the bushings. Also it maintains a constant diameter all the way across. There is a slight dip in front on the stock front bar. M3 sway bushings are much stiffer and are not a block of rubber like stock.
