I just got delivery of an MFactory LSD through Synchrotech for my 335xi, and have some questions:
1) Synchrotech suggests using either 75w90 or 75w140 diff oil with no limited slip additive added. I plan on using a 100% synthetic oil.
a) Which of the two weights would you suggest for the suggested 500 mile break-in period?
b) Would you suggest a different weight before and after the break-in period? (The car makes moderate power, I'm guessing 450-500whp and it's mainly a dd).
c) Is there a brand of oil you would recommend?
2) While breaking-in the LSD some people suggest doing multiple lock-to-lock figure 8s. Is there any benefit or drawback to this?
3) There have been multiple posts regarding coding to disable the Electronic Diff in order to take proper advantage of the LSD and they refer to this article: http://www.onelapx1.com/blog/how-to-make-your-bmw-actually-fun
a) Is there any safety concerns (e.g. upsetting the balance of the car) when disabling the e-diff on my AWD car and installing a rear LSD while my front diff is still open?
Thank you!
