M Performance Limited Slip Differential now in stock

May 8, 2014


Aftersales Business Development and Marketing is pleased to announce the return of the Limited Slip differential to select BMW vehicles! Designed and created due to popular demand, the mechanical Limited Slip Differential provides the extra performance advantage that true performance drivers desire. This differential utilizes 3 clutch plates for a total of 30% lockup on acceleration and 9% lockup on deceleration. This lockup provides instant power to the wheel that has the greatest amount of grip to gain better traction out of tight corners. An additional benefit in low-grip situations is that both wheels get equal power, meaning more forward driving force on roads with reduced traction.

Product Highlights / Benefits:

• Full replacement differential, no modification of existing differential necessary
• 30% lockup on acceleration, 9% on deceleration, developed specifically for the F2X and F3X chassis for optimal traction and smooth locking and unlocking characteristics.
• Integrates seamlessly with the vehicles’ DSC system, no coding necessary
• Better traction in inclement weather
• Superior warranty coverage
• 4 Year / 50K miles when purchased with a new vehicle
• 2 years or the balance of the new vehicle warranty, whichever is greater
• Adheres to rigorous BMW Group test standards
• MSRP pricing $2,895 (2 Series F22 M235i)
• MSRP pricing $2,995 (335i (F30) / 435i (F32))

Yes, see above! It says TBD, but I think that means its coming, not that they are considering it.

There were no manuals available for my dealer to quote the installation or work out for me...however, with that said, they quoted me under $400 to install. Great FAQ!

I am sure this LSD has been tested with a lot of load on. PPK as minimum.
Does anyone know how much torque it can cope with? I'm thinking Pure Turbo + JB4 and meth load for some years ie ~600 Nm.

Alternatively I'd go for the Quaife BMW LSD Conversion.

I have it with PPK right now.
The transmission would probably give before the LSD.

Somewhere between U.K. and here is my Quaife differential.
I went with this due to the warranty and the good references from guys who has it.
Bet the BMW is ok too though.

NE1 with experience on this design type have an opinion on maintenance? I find it hard to believe that this LSD would last 100k w/out rebuild.

Of those who recommended the Quaife, one has many miles on his 335 from 08´and + 500 hp/700Nm.
My Quaife will hopefully deal with close to this when I'll finish my new turbo.

Additionally info: the Quaife differential is locking 80% compared to BMW's 30%/9%.

Correct me if I'm wrong but I don't think TQ bias of a helical is a direct comparison to a clutch type LSD.

"Think"? Come let's here the theory.
If one cant compare directly for sure there is a formula.

One thing for sure the Quaife doesn't have a coupling

An 80% locking is harder to manage and not for all drivers.
Anyone knows the price of MP LSD in Europe?
