Oh, and if anyone was wondering which redline product to use with the MFactory helical diff, Stephen@MFactory told me it's 75w90NS.
I have no idea, the shop that installed for me got the diff fluid themselves, I didn't bother asking since I trust the guys.

How has the diff been working for you though? Have you heard any noise from it? I hear some vibration at the rear sometimes at lower rpms/speeds, but nothing major. Wondering if you hear anything from the rear as well.
