Also considered a 4.44 differential from an E83, but decided on a 3.46 for ease of availability. Not sure if an upgrade over my stock 3.23. Thou I have noticed at-least a 2mpg decrease due to ~500 rpm higher cruising speed. Standing by for your verdict of the 4.44, really really considered this at one point!

I am same as you, torque over top speed turns my crank.
I believe the 6 speed in mine is same as in the M, could be wrong on that.
Car should be ready to drive next weekend so I can report back my findings.
I expect some traction issues with an open diff and estimated 450+hp 
If I can live with that short a ratio, I will fit an lsd |
