The original 33107555607 is discontinued for years now.
The only other option I see for N55 F30/32 seems to be aftermarket diff builders that use a non-oem diff (Wavetrac, Quaife etc) and you need to send them your original core (differential).

I am wondering the same thing. From what I can tell it looks like this one has 3.08 ratio versus 3.15 of the factory diff or the old 33107555607 diff.
What is the impact of the slight difference in ratio other than the ~2% difference in indicated speed? Will the DME freak out and throw codes?
