I'm trying to decide between your metal plate lsd or the Helical LSD. I have a 135i manual, it's my dd would like to take it drifting every once in a while. Is the metal plate a 1.5 way or 2 way. What would the difference in drivability be between helical and your v2 metal plate?

With our plate LSD, you can adjust it anywhere between 1.0 - 2.0 way and in between, as we include various angles for you to choose from.

However, if this is mainly going to be a DD, I would suggest the Helical LSD as it is both noise and maintenance free. The Plate LSD will have some NVH at low cornering speeds, and the plates/springs are maintenance parts

If you're doing an MT conversion, and you modify your oem driveshaft length, you could get your current pumpkin to work/fit.

I know this a bit old but if i'm correct i see that an 07 mt has a large bolted diff and 08 AT has a small bolted diff? yes? So whats the cost for LSD Mt diff? and will a 07 mt large diff fit in a 08 6at car

Upto 03/2007 MT is bolted

Upto 08/2007 AT is large diff. Thereafter is small diff

The diff itself will fit, yes, but you would also need to modify your driveshaft length.

Any way to know if an 03/07 car has bolted or welded ?

I swapped in the mt from the same car so then that same drive shaft will work? also do you guys sell lsd with different gearing I'm looking for a 3.15 instead of the 3.08

@Mfactory - can you comment on whether your products are affected by the Japanese Kobe Steel current events where they misstated steel strength? For the Helical LSD, would a rear alignment be required after install? Thanks.

What kind of advantages would be for a highly modified ( approximately 700 awhp )2007 E90 335 xi, in the case of using a LSD ? Thanks in advance.

@MFactory

If I want to solve the welded differential problem with an aftermarket bolted final drive, but I have some questions...

how can I know the spected pinion shim?
What is the interval of possible measures of the pinion shim?
Have you got any handbook or specs?
It needs the same backlash than stock?

I contacted David @ Synchrotech and he was great, answered my questions.

My situation:
I have a busted E60 diff (AT, 3.46, bolted) - think a tooth let go, it binds every ~3.5 turns of the axle and I hear it clunk. So, seems pointless to send in the busted diff on my car when I know it would force me to buy ($$$) a new ring/pinion set.

I planned to purchase a new E60 AT 3.46 bolted diff online somewhere, and have it shipped to David/Synchrotech to install the LSD in the carrier. I want to be sure I don't buy/send him a welded one, that will cost me more.

My problem:
I cannot figure out how to tell, when shopping for E60 diffs online, whether it is a welded or bolted diff? Is there a part # range for bolted vs welded ? does anyone know?

You don't need to worry about e60 diff. Its same as is on 335s which are plentiful. Most are small bolted. I got one for as little as $80 off a salvage car with 29k on it.
You will love the LSD. Makes a huge difference on drivability in lower gears. That initial torque wave is not interrupted by nannies. Its really a must on cars with 450lbs plus torque.
David at Synchotech took great care of me when I had a recall issue. Great service.

Thanks Ocean, yeah I found that out - at first was told it's hit or miss on which E60 diffs were bolted/welded, and they weren't sure if the E60's were the same as the E90's, etc. ... but then was later told a few days ago when I went back to them, what you said - that they're pretty much all bolted. Found one, bought it, and diff is on it's way to Synchrotech.

Hi,

I'm thinking about switching to a helical LSD, which in my case should be for the bolted 188 diff.

After reading serveral forum posts on various forums I was leaning towards the Mfactory LSD, until I read the following on another forum:
"commonly overlooked benefit of the Quaife over the Wavetrac - the Quaife retains the oil lubrication for the output shaft to prevent the output shafts from seizing".

I realise this post is really old but it made me wonder if the Mfactory diff also retains lubrication to the output shafts.. And if this is really necessary.
Hope someone can give me some info.

Thanks in advance

I read something about a recall on these diffs due to bolt failures?

Was there a specific type and batch of diffs effected?
