I would only use proven components in this area. No use in being the guinea pig. Quaife has an LSD that will fit in the R56 gearbox. I think it's around $1000. Not too bad for an LSD.
I could be wrong, but if I remember correctly, M Factory stuffs are made in HK. I see their advertisements in HK Car Magazines all the time, but personally, I dunno anyone with experience in their stuff. Maybe you can try it out and share your experience with us!
I just had a quaife installed. It was $920+ $1050 for the install+ about $80 for bearings and fluid.
The OS Giken was $1900 eh, not... I wasn't taking any chances with the OBX unit on eBay.
So the Quaife doesn't come with all required hardwares for install? Or did you just wanted new factory bearings for convenience? Did you have the factory LSD before?

You'll need to buy bearings (2) and a couple of bottles of transmission oil:

The Quaife is just the LSD unit. You could reuse the bearings from the open diff, but at only $40 why bother? It would cost more in shop time to remove them than install new bearings. Plus the old unit is ready to go as a spare.
I stupidly didn't order the factory LSD when I ordered the car. While the Quaife is a MUCH better unit, it's also ended up being $1500 more... (factory LSD was a $500 option) I'll remember when ordering any car in the future, if a LSD is an option, I'm going to get it.
Anyway, I'm old, and probably don't have many more sproty cars in my future...lol I'll probabl start going senile and buy a Camry or something else boring and stupid...lol Nah....
Thanks for your email. Our LSD is in stock and compared to the Quaife
our entire unit, from the casing to the gears are forged steel. This
has enabled us to breach the 1,200whp mark with no issues on our very
own drag Honda.
$817.95 USD which I presume is shipped price to UK. Work out about £512 plus taxes if I get VAT added and Quaife is £660 here.
Don't think it is worth the risk as only just heard of Mfactory where as I have heard about Quaife for years.
I am just wondering if anyone had the experience of moving from the factory Cooper S LSD option to Quaife. Is it noticeable difference on street and track?
I currently have the factory LSD option on my R56 Cooper S, but I don't think it's quite enough given the torque. Would it be worth it to move to Quaife? Or would it be keep the factory LSD or move to OS Giken?
I have installed and driven all three. I Own a 2010 MCS with the factory LSD. In stock form, the lsd makes a world of difference. The car can precisely pull through turns and leaves clean feedback for the driver. Simply put when you exit the turn the wheel stays in your hand. However once I turned the power up the show went out the window. being that the MINI helical type LSD can't achieve a full lock when I put the power down it pulled the wheel out of my hand like an open diff car. When we installed the quaife we found similar results. turn in on power and decel was normal, and the car behaved like stock. straight line torque steer was all but eliminated. And I will say that it seemed as if the quaife unit was able to hold a bit more while powering out of a turn before the feeling of torque steer took over. However it wasn't my car that I was driving so it's hard to say. The quaife is a great option if your looking for a Diff and aren't looking to break the bank.
The OSGiken has the disadvantage of being the priciest of the bunch, but I have to say, it's worth it. Being that the OS model uses clutch's the Diff is able to achieve a full lock. When we built our shop car we decided to leave the drive train alone until the power goal was met. We were curious to see what a stock MINI would do with that much power. With a bigger turbo and 250lbft the car suprisingly handled rather well. only under heavy acceleration did the car pull hard to the right. however with the open diff turn's were unmanageable. The car would provide nothing but torque steer the second the gas was applied. After the install that all changed, power delivery was completely up to the driver. torque steer is all but gone, and the diffs ramp settings were almost perfect from the factory. It grabs around turns and pulls the car through with out a struggle. I strongly recommend this Diff to anyone that can afford it, you won't be sorry.
Shame can't find anyone who has used the Mfactory unit in a mini. It seems to be forged rather than billet and tolerances seem good from Honda reviews but as it is such an unknown I might as well plump for the Quaife unless I can get a good deal on the Mfactory item.

Thanks for your advice! So I guess it's either keeping the Factory LSD or get the OS Giken LSD!
Just one more question, with the OS Giken LSD, how often do you recommend to change tranny fluid?

This might be far fetched, but at what torque value did you notice the factory LSD beginning to misbehave and act a bit like an open diff? I have a factory LSD in my R56 MCS right now and will be running a hotter tune soon that has around 235 ft-lbs of torque. I'm kind of exploring this area for my knowledge since down the road my gearbox will probably be out for the inevitable shotty R56 clutch problems. Based on what you're saying it seems as though the Quaife makes more sense unless you're pulling some big numbers from our little engines.
1k initial then it gets a bit hairy from there. OS doesn't really have a recommend interval for the MINI's but they have said 30k is a good idea.
It's hard to say where the car is going to let go it's going to be based on alot of different values. tires road type temp where power is delivered weight in the car. if your making 250lbft your going to over power a helical diff. but it's still better than nothing

Y'all might note that my Quaife is at 176k miles and solid as a rock. Mind you that surely isn't 1,200 HP, but it is damned durable.

30,000 miles per tranny fluild change? That's awesome!
Previously, I had an ATS Carbon LSD in my RSX and they recommended a tranny fluid change very 2,000 miles or 3 months and I was told to use the most expensive tranny fluid from Motul and it cost like $200 each time. I thought that was too high of maintence cost and the LSD also cost about $2K as well. But yeah, if the OS LSD have a much lower maintence cost than the ATS one, I think the high initial cost is definitely bearable then! Thanks man for the comments!
If the time attack fellas or the MINI challenge guys aren't using it, I wouldn't touch it.
Well I personally am looking for a LSD, I am not going to be putting my car thru anything like time attack or mini challenge as most of us are not. So I am thinking the phantom LSD may be the ticket.
I have my transmission out right now to install a SMF and upgraded clutch, I'm curious if anyone has yet had an MFactory LSD installed in a MCS. I did find some positive reviews over on the Golf and Bimmer forums, but none for Mini yet.
We carry it here MF-TRS-05MIN , also here are the new bearings for each side linked , so you dont have to reuse the old ones. Fits R56 - r59 S /JCW also.
