135i with Welded Diff
I know a lot of you have the 135i with the Welded Diff, therefore our bolted diffs on sale above will not fit.

Our solution for you guys is simple: We will make a new Ring Gear for you, one which is compatible with your oem Pinion (we can even make new ratios for you guys, if the interest is there?). So instead of spending $600-700 on so-called "install kits" and the lead-time associated with shipping your oem diff back-and-forth just to be able to install an LSD, you will now be able to purchase the correct ring gear for ~$300 (tbd, but it won't be more than this), no hassle. And yes, the ring gear will work with a competitors LSD as well

In order for this to happen though, we need some assistance from you guys. We will need an oem sample 3.07 diff (with welded ring gear + pinion)

135i DCT
Same as above, we will need to make a new ring gear for you guys, therefore, we will need an oem sample 135i 2.56 diff (with welded ring gear + pinion)

Any questions, please feel free to ask!

Any progress on the fabrication of the new ring gears.

[MFactory]

Underway just now. Will keep everyone updated

If anyone wants to join the group buy and get the 20% discount, please PM me asap. As of Monday June 2nd, we will no longer be offer the group buy on the large bolted LSD's.

Thanks!

I just started looking into lsd's a couple days ago and I really don't know too much about which one I would need.

A couple stupid questions....

How do I know if mine is welded or bolted? (I have a 13 135is 6mt)
Is the only difference in the AT and MT the final drive change? So if I want the 3.46 gears I would get the AT diff?
With the significant price difference in your LSD from quaife/wavetrac/etc, what is the downside?

I'm very interested in adding an LSD very soon so answers would be much appreciated.

[MFactory]

All 135i MT's are welded, and all 135i AT's are bolted.

The actual pumpkin size is different, with different differential and final drive.

As you have the MT pumpkin (the large pumpkin), if you wanted a 3.46 ratio final drive (which is available in the large pumpkin from early model 335i AT's), we have these cores in stock at the moment for $1500 (inc new LSD) + $500 core exchange (refundable) + shipping

There are no downsides to our LSD, only positives over the others

Are there any issues when changing from the 3.08 to 3.46 gears? What's the difference in price between the two as well?

[MFactory]

There are no technical/fitment issues, however, it is a shorter ratio, so you will lose some top speed in each gear whilst at the same time gain slightly better acceleration in each gear (which is a good thing). People will tell you about decreased mpg, but this is a mixed response. If you highway cruise a lot, you will get less mpg, but vice versa, if you traffic light a lot, you will get higher mpg due to the increase throttle response (less throttle required to accelerate).

with the 3.08, you will need a new LSD and new Final Drive (Ring Gear & Pinion, which we are making). The Final Drives are still a couple months away, but will be a couple hundred more expensive than the current OEM 3.46 option we have just now as these are reconditioned oem final drives.

Do you have any idea on what sort of RPM it will bump it up by?
