Is the M3 rear subframe better than 335i rear subframe

cape335i · 09-13-2021, 08:04 PM

Want to upgrade my E92 335i to an LSD and it seems that replacing the open diff with an M3 diff is the most budget friendly options. What I want to know is if I should replace the whole subframe and put an M3 subframe on or if I should solely do the diff?

M3 uses the same subframe but with stiffer bushings, both subframe to body and diff to subframe bushings.
