What is the budget? I just want to know so I can suggest something that costs a lot more.
I vote - none of them, get a limited-slip differential + M3 subframe brushings.
If I had to pick from your list, I would do FMIC for sure, on an N54 it is a very important mod (especially w/ engine mods). Get the Helix one.
