- In this video I show you a limited slip conversion kit that fits many BMW models.
This kit is a cost effective way to convert your open differential on your BMW to a progressive rate limited slip differential for only a fraction of what a fully assembled LSD would normally cost.
Here is a link to demonstrate how this kit works:

I'll be doing a follow up video showing the install process and a demonstration video.

What the heck? Every thing I think about buying and try it out. Them you make video about .man your amazing
Great explanation on the mechanicals of the progressive ramping. I didn't know this one had that.
I came across this last year and was pretty intrigued. I have a manual trans though 😭
Have been thinking about trying this out so glad you have pulled the trigger. Cant wait to see the results.
That's super cool if you became a distributor I'd buy one
Very interesting! looking forward to the DIY
The explanation of the locking mechanism is wrong. It has nothing to do with centrifugal force or inertia and it does not twist in the way that you demonstrated.
Very Interesting. Can't wait for the DIY and your opinion once it's installed.
Can’t wait to see the DIY, keep up the great vids man! I hope we get some pretty parts for our auto trans soon or even the manual trans is like to push 1000 and not worry about trans anymore
Looking forward to see how this goes. Been watching your videos since i got my 08 last november. Great content. Thank u
I posted this product to the FB Groups! I’m gonna be ordering this for my e92 6mt!
Dloves-Garage I'd like to get one for my 6mt also, let us know how it goes!
Where can i get one from any links?
yeah.. i'm not cutting off my ring gear ( have manual 335I ) and you shouldn't have to, the spider gears can still be removed and refitted, you can even use the hubs to hold in place, then use the dif pin when installign side gears for proper alignment, remove center pin, and rotate into place install LSD, and center pin.
Super interested in this and after the install vid and demo I may just be a buyer. Thanks for this too.
Can't wait for install vid, cool find
Man cannot wait till you do this, awesome vid
Im really interested in this option for my e90 335i. Let me know how it goes, I'm putting down 471 wtq would love to have this added to my ride. Good looking out even if it doesnt work.
Love ur channel n content brotha! Also, absolutely loving the new intro lol not gna lie man I'm glad u changed it.. keep up the awesome content! 👌🏼
07 e90 335i
If anyone is in the Dallas area and needs to have the machine work done I can point you in the right direction. DNS Tool did mine for $100 out the door. Great folks and they do quality work.
Whoever makes those should make them for all cars. That will actually work as a functioning LSD. The Phantom grip was more like a diff Locker/welded diff.
I wish i'd known about these before i payed £1660 (about $2k probably) to instal a quaife in my 330d! Anyway, it's done now and i love it! I've posted up a video on here destroying my old tyres before getting new ones fitted which demonstrates why all reasonably powerful RWD cars should have LSD 😈
I need one, I've been so close to welding my diff.
same
Same
I just got mine kit for e92 today))
is it easier to drift now?
The kit has been upgraded since this video (2021) and you no longer need to grind or change the spider gears on the 335 Auto Trans version.
Interested to see how it lasts, Quaife or similar is what I plan to get one day
Yeah I'm hoping it holds up, if someone made a Torsen diff that was $600 or $700 I would have gone that route.
@@VehicularDIY For $1000 www.teammfactory.com/catalog/partno/MF-TRS-05E46A or they have the larger differential cases available rebuilt with a core exchange. While you are there, swap out the rear subframe bushings at least for the stiffer M ones. Good time to install the 4 rear M links if you want to upgrade handling.
Always interesting and high quality content. I am not completely clear that this would be as good or better than a full rebuild (but the cost/benefit is really attractive). Because I have a very similar car (09 335i S0704, AT, LCI, and metallic black, except mine has all stock parts for the moment) I am also considering a full LSD replacement diff, having some do the engineering for me (diffsonline)
Thanks, how much were you thinking of spending overall?
@@VehicularDIY TY for asking. For just the diff? I was ready to spend about $4500 (3 angle, polished, remanufactured housing, the works) and for the rest of the car? Probably another $10-15K, and most of it is only parts. More challenging things like upgrading the diff (meaning, changing the actual diff internals) I am only slightly comfortable doing that myself. 90-95% of the rest, I am slow but capable to most of the work. I can send you a list of things that I have targeted and budgeted this year, if you privately message me.
@@SteveWeltman Highly recommend you check out MFactory or VAC Motorsports. Nice to get the larger case differential if you have the small case post 09/07 one. Your budget is more than sufficient.
Amazing. I have a 2009 E60 - 535i. I have Full Bolt On's with 415 whp. Will this work on my car?
Yo i have a 2008!!! Do u have an Instagram or something so i can see ur whip?
I'm doing a full M3 lsd video.. I'm more than hesitant on these solutions as they just seem super dubious to me, not a knock on you
Nice, yeah I understand where you're coming from. From my perspective it could work and it would be a neat solution for viewers or it fails but made an interesting video so I'm fine with it either way.
@@VehicularDIY One should consider the possible consequences of a catastrophic failure vs. the limited benefits of one not occurring, I should think.
@Max Nix Don't attend to convince you in oposite, but we have been selling 2 sets daily for last 3 years. Not a single diff came back with damage, so it is perfectly safe. Anyway would you be interested in shooting video for M3 diff rebuild with our parts? We have clutches, shimmes, bearings...
@@RacingDiffs I'm the one doing the rebuild.. it's for my channel BMW Dad. Let me know if you are interested.
Definitely interested, I want to see it really get put to the test first though. And yea, having people bench grind prob isnt a good udea unless they know what they're doing. Imo
Noted, I thought It would offer value to show it can all be done at home but you guys are right. Most anyone can just drop of the gears and axle flanges to get them machined at a machine shop for relatively cheap. I place on taking off the boost by gear in MHD to really see how it preforms.
@@VehicularDIY sick man! Can't wait. I'm def game for this if all goes well! I have a machine shop next door to our hanger, so I'm ready lol
Subscribed can't wait for next video
Dude this looks awesome! When are these gonna be available for purchase?
Dude, lsd transmission fluids prevents from lock up, lsd clutch slide in it, not otherwise
Hell yeah I want one! ☝️
It looks very interesting would that kit work with a dct transmission or does the dct rear end ring gear need to be machined? I own a 335is with a dct and was told to just buy a used m3 rear end from a bmw salvage yard for $500. If this works for half I might consider this option. Great content I want to thank you for saving me $$$$$$$$$$ of dollars every DIY is spot on.
Ring gear is welded on. If you go M3, you have to replace the whole subframe and brakes, suspension. Modification of the pilot shaft is also required. If you cannot afford to swap a pre-built differential in with a core refund (about $2.3K for the unit without core return), then seriously just skip it and keep your fluids fresh.
Awesome videos man, I saw the video that says the company reached back out and gave you your money back iow “sponsored” your video. Did you by any chance ever setup the distribution in the US or get a discount code ? I’m looking to do this same conversion but to my e53 x5 to help with traction off road. Please let me now. Thank you for all the info and taking th time to make these videos 💯
Oops, sorry. I just saw your reply to another E60 owner.
Im interested if some friction modifier would help the ”clutch discs” to work maybe better?
Im interested in this
Where do you get the kit? I have eaten up the rear end in my 2008 E93. Luckily I have an early 2007 E93 parts car with the larger differential so I plan to upgrade and install that one.

Would this be okay to use on an xDrive vehicle? Thinking about doing this to my E70
Would this fit a 2013 F30 335i xDrive with manual trans? I am in the US and would be interested.
It looks like it could, I will ask the company that makes this kit to chime in to confirm.
We are in for tech support. There is a set available for your model. It is 215LW. 👍🏻
Will this fit a 2009 lci e90 335xi manual?
How long does the shipping take they gave me a date of November 1st
Link please. Thanks great video
Would this work on the rear diff of a 2000 bmw 323ci???
For your model there is another version of the set. And now is a good time as Black Friday promo is on. Check link below

Can you do an update review on this?
Pretty disappointed to be constantly screwed over with my manual e82 135i. First it didn't come with a LSD from factory (what was BMW thinking??), then I've got a housing that can't be swapped for any factory fitted LSD's, then the bloody ring gear is welded to the centre. Turns out to be cheaper to just buy a converted diff with a LSD on a swap basis anyway. FML.
How is the diff today March 2020.?
So far its still holding up great.
@@VehicularDIY wow that's a testimony for sure. Going to put one in a Datsun Z ,and put a Subaru lsd in my other Z see price verses performance. Thanks for your reply and this well done video.
For e46 coupé 323i?
This is completely unrelated to the vid, but what’s the intro song you’re using?! Love how simple and clean it is by the way!
Thanks! I'll find the song name and respond. I got it from Epidemic Sound.
Very small cluch vs oem
Pretty cool and inexpensive option, if it works the way it's supposed to. Have to research what my diff is (on 128i automatic)
Yeah I'm pretty sure it fits your car, you should have the smaller 188 diff.
It is 188 diff 👍🏻
I’m interested but I have a Manual. It sucks that manual cars have to get it machined to work
So manual difs has welded the big main ring? I cant take them apart?
Can I get this in the UK?
Looks great! Will it work on a 335xi? Also the kit should come with an optional properly sized spider gear. I’d rather pay for the right sized part rather than risk screwing around with a grinder which I don’t own.
I believe so, I'll ask the company that makes it to chime in on this video to confirm. Yeah that would be a nice option to keep things simple. I was considering getting a mini lathe to do the work but then it wouldn't make a very good DIY as nobody has one. My DIY might seem crude when I make it but I'm hoping to show it can be done at home without any really expensive tools.
We have it for 335ix rear differential.👍🏻
does it still hold up?
Will this work on 2012 335IS DCT without remachining
I am interested in doing this to my n54. Did you get a way to distribute from the US?
Does it fit 325i, 328i and 330i? How's fitment with manual diff on these cars?
I'm interested in this. I believe I read in the comments that someone stated the company you will be affiliated with now offers an "machining free" install. Do you have any knowledge of this? Not really confident in finding a machinist locally. Thank you.
Very interested for my 09 135i manual. Please let me know. I have a welded ring gear and large housing. Been looking into some of the possible options. Don't drive the car as much. I'm thinking this would be great for me. I've followed pretty much all the upgrades you have done, even the turbos. I do have a machine shop that can help with a lot of the work. Thanks in advanced. Peter

How about daily use?
Yoo would this fit on an e60 535i
Yes the installation guide lists the E60 as compatible as well.
Just a heads up, bolted or welded ring doesn’t only depend on if it’s auto or manual.
Here are all the versions of diffs:

Awesome, thanks for sharing. Seems like the early auto 335i had a welded ring gear.
Vehicular DIY yeah man, I didn’t want you to disassemble your diff and discover it might requires more works.
Do you know if I can switch to lsd on an automatic 2008 335i? Im having trouble finding info on it
Yes you can. And now it is a good time as Black Friday promo is on. Check link below.

where can I get one of these ?
can it be used for z3?
1 way or 1.5 way?
335xi automatic?
What does this ultimately give you better handling? Or
I'm doing it for better traction but it does help with handling if you're in the middle of a turn and need to power out.
188 L ?
This is going to be very funny
Interested
I would like one i have a auto 335i e92 fbos water methanol ect i live in Australia and my only other option is a lsd for $1800
Okay it should fit and you probably have a bolted ring gear on your diff if it's an 08 or later.
@@VehicularDIY not sure i haven't checked it out yet its a 07 335i e92
@@tighematthew Yeah, you should have the bolted ring gear. The big question is do you have the auxiliary oil cooler as it was only on some properly optioned cars that year?
@@maxnix346 oil cooler on the diff
@@tighematthew we have the set for you, so you can order it from us directly. Www.racingdiffs.com
If you are not sure about fitment, please send us message through web site with your VIN and we will check it for you.
Im interested , does will work with the e90 335d?
Yeah they make a version of this for your car, you have the 215K diff.
@@VehicularDIY thanks man , already send them a mail .regards
Also honestly I'm shocked you would go to this solution since you tend to do more in depth, permanent and solid solutions for your car.
Oh well.
I think my channel has a fair share of really budget oriented solutions which might not always be the best recommendation but for some people is relevant content. For instance one of the first videos that got this channel going is an injector DIY and I used rebuilt ebay injectors of all different indexes. Lasted a couple years but not necessarily the best move on a tuned car, eventually did a follow up video with index 12 injectors with an explanation as to why people should go that route. I'll definitely let you guys know if this LSD retrofit doesn't last or work.
Skeptical
Where can i buy this?
You can try their website.
Would an M3 diff swap be an option?
That's an option yeah but you need to do the complete sub frame I believe.
@@VehicularDIY Correct... Rear carrier, diff sub assembly, but might as well exchange the axles with the M3, also you'll need to adjust the driveshaft; the ends are different for the M3 and the length is different (esp for the E92 M3 to E90 sedan). Its doable but pretty involved job.
@@SteveWeltman yeah the budget BMW guys did it big job..
Tighe Matthew I watched that video too. Wow, what a process!
Dyi please
Yeah hope to have that out no later than 2 weeks from now. Been busy finalizing my M Sport conversion, that took way longer than expected.
do you know the torque limit for this kit?
I don't but I can ask the maker of the part to chime in, all I know is I'll probably be testing that limit as I make over 500 WTQ.
@@VehicularDIY No cause for pause then? Hmmmmm........
We tested it on e46 330d woth 400bhp and 600nm torque. Actually it lover the power! The more power you have, better it'll work due to progressive response.👍🏻
Wow, well first off, clutches are a wear item. So even if this operates as claimed, durability has to be highly suspect. That is a lot of labor having to remove and rebuild your differential for maintenance. Also, true clutch differentials have a lot more materials with multiple clutch and driven plates with much larger areas involved, thus more evenly distributing the thermal loads. Lastly, you are going to have to throw away your differential if this fails as it will be too destroyed to rebuild.
The optional mechanical differential offered over the last two years as a port installed option on F3X and F2x BMW is a Drexler multiplate clutch design.
I would say that this "LSD" clutch design is rather like DCI intakes in that if such a less expensive arrangement worked as advertised, the OEM would have put them into production to save money and reap the performance benefits. That they have not should raise a very large red flag for anyone contemplating that he is a better engineer than ones OEM is hiring.
If nothing else, I would have a completely ready spare differential ready to swap when this one fails. The automatics produced before 9/07 used the larger casing like the MT and DCT differentials but still had the bolt on ring gear. For anyone that has a 6MT or DCT differential with the welded gear ring, it is not a trivial job to remove for even most experienced machine shops. I would therefore recommend looking at reliable suppliers like Trac, MFactory, DiffsOnline or VAC motor sports who have the necessary experience.
I would really reconsider this if you are hauling your family around 610 and have your differential seize at 80 mph. All risk and limited benefit in my estimation. Would hate to lose you that way. Also, no matter what happened, you would be instantly 100% liable for any damages that were self inflicted or occurred to others. Insurance would most likely decline coverage.
Please don't hand grind it, take it to a machine shop or find a lathe.
Yeah I guess it's reasonable to expect anyone following the install guide to find a local machine shop.
I am interested in this. I have a 2008 135i automatic. I have a build topic on 1addicts.com. I am located in Finland Europe.
Nice, given you're in Finland you could order it direct from the manufacturer in Serbia and probably receive it within a few days.
Absolutely! We ship with DHL express 👍🏻
This kit is crap. Look pazi88. The chlutches are too smal and work in a low horse power 520i only a half year.
Tell us wizard, how does it "lock up" the diff side gears, inertia, centrifugal, rotational, progressive, blah, blah, blah!!! You have been hoodwinked.
lol nice ramp on both sides to if u down shift hard it locks up whould be nice for the ramp to be on one side only like a 1.5 way only weak point is the way u retain the pin this is why even the phantom grips exploded the shock load on pin whould shear the spring pin holding the spinder gear pin in place causing it to explode back in day fixed this prob use to use them in shitty sohc honda transmissions used bearing roll pin and 2 allen grub screws to keep it in place worked well fixed the ware problem by adding oiling path to the spider shims and a thin path on the phantom grim at a 45 degree so it pulls oil in going forwards also trans needs to be bit over filled so oil level is covering bit above half the drive shaft inlet this keeps the botten section of the diff in oil under rotation so its lubricated better st oem level diff tosses oil away from spiders when u spin hell out of it and the heat builds up on sliders due to lack of oil cooling and lubrication also for drag racing no oem spider set will last on open diff iv blown few oem diffs up to weak points the diff spiders then the phantom grip it just increases chance of spider blowing up because u got more power gettimg to tires vs tire spin
OMG i get so triggered when this Serbian spider gear grinder and diff killer is being called an LSD omg its not lsd its shit, but an REAL LSD or weld it if you have no money.
