I installed an M Factory LSD for my 2009 e93 Automatic. So far, it works as advertised.
Car feels super stable taking off, peeling out in rain or dry road, turning corners and all around driving. Like it's on rails or something. The car feels like a different car than before the install. Solid and easy to control when let loose and burning rubber around corners.

This unit is mated with a Propulsive Dynamics upgraded tranny and it is perfected mated. Highly recommended to use with a PD unit! Traction control does not come on as much and when it does activate it is very short and less intrusive.

Customer service was very good and responsive. Ordered direct from eBay.
Installation was fair easy if you have the right tools - the big 55mm wrench to take of the collar nut of the drive shaft. I did it by myself in a day.

Overall, I highly recommend it.

Hopefully you used a 50mm

Oh, it's you again. I see you have not lost your habits.
A simple "it's a 50mm" would have sufficed. But hey, old habits die hard.

Here you go my lord. This is the exact tool I used and own.

What brand of zip ties work best on oil lines?
Are we going to do this again Aaron? You gonna come to a thread and turn it into a "look at me" thing?

So, go ahead and make your recommendations on the zip ties. Obviously I have no idea what I am doing right? So go ahead, post the thread with the zip ties and teach me a thing or two...but for the love of Zeus, don't waste time here with your passive aggressive comments.

I thoroughly enjoy my MFactory LSD in my 2.56 DCT diff. The car really opened up when I disabled the E-Diff, much moreso than when I first installed the LSD. There is a uphill right turn leaving my neighborhood and before disabling E-Diff, the car would STILL reduce power!

@LMB335is made an awesome video to perform this coding, if you are inclined:

I had that disabled in my car... I disabled a few other things too.. .I might put a couple back in fact for safety reasons.

I also have the Mfactory diff. What did you code out and why, and what are you thinking of coding back in?

The reason I ask is I'm RWD and traction was bad this year in the snow. This was my 4th winter on Michelin X-Ice3 tires. There is still good tread left but traction is awful at this point, so I'll get new snow tires for next year. I want to code out any e-nannies that aren't needed but I'm hesitant to code out anything that help with traction in the snow.

I almost never have the nannies interrupt anymore since I installed the M Factory unit. Previously it was annoying as hell every time I stomped.
