In for updates! Looking forward to hearing the results of this, wish we could see a lap time comparison for this vs some of the others in the same car with same driver on same track... But that's just the scientific side of me coming out haha

Ordered new oil seal kit for the halfshafts, gasket sealant, loctite red, can't find any part numbers for the crownwheel bolts though as I want to replace them as well.

Wish I could install this myself. I have no idea how to mess with the internals of a diff.

What's the cost of extra parts and install? What kind of shop is installing it? I don't have any "performance" shops here but there are transmission shops

It's mainly just bearings/seals and setting the back-lash on the diff.

We also offer an install service if you send us your core (or we can send you a prebuilt core first for a $500 core exchange fee that is refundable after you send us your original core back) for $400 + shipping, which includes a full recondition of your core (i.e as good as new)

Just imagine it; You're sitting at the line, waiting for the Green to light up on the tree, you disengage the clutch then bam, big cloud of tire smoke but you're not going anywhere! You're not the first, and most certainly not the last, to experience the One Wheel Wonder syndrome

Or how about when you're going through that tight apex, approaching the exit point, but no matter how hard you accelerate, the competitor who was right up against your rear going into the turn is now leaving you for dust as you exit? He obviously has an Limited Slip Differential (it's never the driver :p)

- If the answer is YES, MFactory Competition Products is the answer to your prayers!

Introducing the MFactory range of Forged Limited Slip Differentials. By precisely controlling the transfer of torque between the left/right wheels, you will gain maximum traction, allowing you to eliminate the "One Wheel Wonder" syndrome during drag racing and power through those tight corners on the circuit with maximum exit speed.

Helical LSD - Model shown is for Honda. I will upload the BMW image asap


Description: Also known as a "Torque-Biasing Differential", the 2nd Generation MFactory Helical LSD is lighter, stronger and more efficient than any other Helical LSD on the market today! Through the use of maintenance-free Gears, this eliminates the need for special fluids & rebuilds associated with plate-type LSDs. Lock-free operation also ensures no adverse affect to steering response
Suitable for: Street Cars, Drag Cars, Occasional Road/Race
Power Rating: 1000whp+ (As proven in the world's fastest Hondas)
Warranty: Lifetime Transferable Warranty (even if raced!)
Why MFactory?: Our Helical LSD's have been proven to be Stronger, Lighter and have better tolerances than our competition

Feel the Torque***8482; Guarantee: An industry first! We stand by the quality of our products so much and, fully believe that you, our valued customer, will be fully satisfied with your Helical LSD that if, for whatever reason, you are not happy with your purchase, you may return the product to us for a full refund (excluding shipping costs) within 30 days of the purchase date!

Fitments: (Please contact us with your exact Model/Fitment)
BMW E46 with <= 3.07 ratio final drive
BMW E46 with >= 3.15 ratio final drive

Price: All fitments $999.95 inc FREE Shipping within North America/Europe/Asia-Pacific
Group Deal: Combine 5 orders, and price is now $799.96. That's a 20% Saving!

Want us to rebuild your core for you so that it's ready to install?: Simply ship your pumpkin to us and we'll handle the rest:

- Prior to assembly, all parts are cleaned, inspected, and polished in a deburring machine with ceramic media
- Preload, gear clearance and torque will all be inspected and adjusted for superior performance
- Housings are media blasted to give a 'better than new' look
- Simply add $400 to the above price



...... If you have any questions, please don't hesitate to ask

Why is there a $100 dollar price difference/price change between the two ?

My apologies, should be $400 + shipping. I was thinking of the larger E92 diff which is $500.

Thanks!

If you are able to take off your oem bearings without damaging them, they should be good to re-use (we find this in most cases).

I would have to get a new unit anyway because my diff is a 2.93 and the lowest you offer is a 3.07

The final drive is a separate part from the differential, so it doesn't matter what ratio you have, you would reuse your existing final drive

Cool. Looks great on the outside, like the quaife for my civic type-R. It has taken 150 000km beating on the street, track and autobahn.

Interested in your comments since I was planning for the quaife for the 330 cabrio during next winter overhaul.

How do you set the backlash? Are there shims provided? With the honda quaife needed shimming.
