This is a rare, 215mm automatic bolted pumpkin and was built by Synchrotech which is MFactory's US distributor. I ordered new bearings and I still have the warranty card for it dated production batch March 2017.

The part that makes this rare, is the 215mm carrier, which is usually only found in manuals and DCT's. The normal size for the auto is a smaller 188mm, but this one is 215 which only came on very early build automatics. It had very low miles when I got it, less than 20k if I recall and I've only put about 3k miles on it since it was rebuilt with the LSD. This is notable since the 215mm housing will fit the M3 finned differential cover or the 650i finned cover. I have a brand new 650i finned diff cover I will include for free with the differential which I never got to use because it won't fit with the convertible rear brace in the way. The only reason I am selling, is because I am doing a DCT swap and I need a 2.56 differential instead. Absolutely zero abuse, have never done a burnout or launch with it.

Did you sell this yet??? Also has anyone swapped to a 3.46 in a manual? I know I've seen mixed reviews. This is exactly what I wanted to try.. but didn't wanna pay big bucks to just try.. this may be the solution

I know Omar was using a 3.46 with his 6MT swap. There was also a thread on a different forum about it and it was pointed out that the new M4 uses a 3.46 with gearing that is very close to the 335 6MT. I had originally thought it would have been too short, but unless you're running 140 in the 1/4, it's probably fine, and I'm sure a good bit more fun around town.

Technically yes, there has been a deposit made. I can't sell it until I get my LSD. I can't get my LSD until the scrap yard delivers my differential to be built.
