Great work. I see at 9:23 the oil seal bearing housing is scored/gouged/pitted. in the process of changing my half shaft output seals I have managed to gouge the oil seal housing surface right where the seal sits 😖. The oil seals I was suggested to use apparently don’t require any sealant applied around them,I was hoping I could file down the gouge and apply sealant to take up the void I created, any thoughts? The diff is the M Performance lsd for the bmw F series platform. Many thanks if you could get back to me with any advice. All the best, Ant.
Dear Ant, we recommend sealant even in case of full rubber seals. It won't do any harm. We suggest to use sand paper to get smooth surface as much as possible and return seal with sealant paste.
So if I mailed you guys a diff, you'd install is for 300? Wonder what two way shipping is from the states for a ready to install diff. Still under the price of the other options I bet. Even better is if you guys could source a diff locally to avoid double shipping... Something to think about.
@jf269 I'm afraid that shipping from states to hear would be tremendously expensive. We have the best possible contract with DHL and shipping for the complete diff is about 400 usd.
While i like the product....since i have to apparently machine the damn ring gear I'd just upgrade to a wavetrack or quaife. This takes out the stock weak inner gear and pin. Installation without having to machine would be totally different
@RacingDiffs ahh...thought there was both room and an access hole to remove the pin to slide in the unit much like similar kits for earlier chevy open diffs. This would still be cheaper but I feel with the cost of machining I'd just replace the whole unit to something far stronger overall. Otherwise a nice product, just not for me. I also have the option to buy the factory bmw lsd rear pumpkin, which costs about the same as doing a wavetrac...just no down time...plus an extra diff should tragedy strike
Yes we do. If it is automatic transmission, then it is 188LW diff type. For manual transmission, you need 215LW. Check the link below. racingdiffs.com/collections/lsd-conversion-sets/products/bmw-e46-e90-e92-e39-e60-lsd-conversion-set
This is even more complicated as you have to drill the crown gear and make threads in something that is super hard (60Hrc). Also you have to set backlash too.
Great video tutorial! Absolutely spot on and appreciated. Would love to reach out and grab some tech drawings if you have developed them.
Thank you! Just drop email to production@racingdiffs.com
do you sell complete units for the F30... with all of this work done?
No, sorry
Is it the same procedure for a 2018 f20 120i?
Yes.
What are then names of flanges are ground down 4mm? and is this a requirement? What is the purpose of that?
That needs to be done in order to make a clearance for conversion kit.
@@RacingDiffs I understand this... which part is this? on the output shafts?
I don't understand too...@@mitchellthompson2798
Yes, but which flanges? Axle side? The axle on the 128i has the flange. The input shaft on the driveshaft side?
Is it possible to do this lsd for F32 440i 2018?
Yes. That is type 215LW. We have it in stock.

Does the oil need to be 75w-140 now in that diff case? or still 75w90?
Yes, it requires 75w140 LSD oil. We recommend Motul Gear Competition
Hello i have a bmw f20 n13 do you have anything for my car??
No, sorry.
I'm assuming the process would be the same for a 2010 330d auto?
That's right.
@@RacingDiffs perfect, just placed an order 😊
Intalling the same kit on 215 diff, what gas do you use for welding, Argon or Co2 ?
In this video we used argon, but cam be done with co2 as well.
Hi!
I own a 2017 f30 330 b46(252hp) 6 manual RWD, will RD5010(from your website) fit it?
It will fit👍🏻
Great work. Is it possible to do this lsd for F30 320d LCI 2018 rear wheel drive (no xdrive) car? Thanks in advance
Yes, the procedure is the same👍🏻
Hi, which kit is suitable for my 2015 435i xdrive?
Unfortunately we don't have set for your model available yet.
Hi! Will it fit to 2012 F30 N20 184hp ( 135kw ) 3B11 LHD manual RWD ? How much % of lock does it provide ?
Unfortunately we don't have a set for your model.
@@RacingDiffs And what about automatic gearbox ? Will it fit to automatic Z8HP ?
@@jakubkruszewski1610 sadly no, as the doff is the same.
Now to just find a machine shop willing to do this...
Im busy installing the same kit... With what filler wire do i need to use to weld it back up?
We used steel wire with tig.
@@RacingDiffs any specific type?
@@julianjacobs8244 no, you can use anyone.
Which diff type would work for the 2013 f30 320i?
Unfortunately, we don't have LSD kit available for your model.
Great work.

@@RacingDiffs you legend! And what a fast reply. Thanks so much 👍
@@anthonyh958 you're very welcome!
how much this kind of thing would cost? if i send my diff somewhere to be manufactured like that?
We charge 300eur for installation.

How do you imagine installing any aftermarket LSD solution without machining the ring gear off??
@RacingDiffs ahh...thought there was both room and an access hole to remove the pin to slide in the unit much like similar kits for earlier chevy open diffs.

A factory BMW LSD unit for F30? Never seen one of those except in M3 F80 that doesn't fit even close. Anyways, appreciate the comments 👍🏻
Do you have kit for F30 340i xdrive?
Yes we do. If it is automatic transmission, then it is 188LW diff type. For manual transmission, you need 215LW. Check the link below.
racingdiffs.com/collections/lsd-conversion-sets/products/bmw-e46-e90-e92-e39-e60-lsd-conversion-set
do you have a set to m140i 2016?
No sorry.
Doesn’t it need any coding for this?
Not at all. It works great with all assistances 👍🏻
Postoji li set konverzije za Bmw seriju 1, f21 120d?
Na zalost nemamo set u ponudi za taj model.
@@RacingDiffs na bmw fans stranici pise da je diff typ 188LW, znaci to nije taj koji imate u ponudi?
Ako ste sigurni da je taj diff u pitanju, onda za njega imamo set. Ugradnja je nesto komplikovanija ali se moze uraditi, naravno.
Pentru un bmw f20 120d WBA1C31020E959007 aveți kit?
Diff tye 188LW. Check the link below 👇🏼

With all that work, you might as well just install a real LSD.
This is even more complicated as you have to drill the crown gear and make threads in something that is super hard (60Hrc). Also you have to set backlash too.
Is it possible to install an LSD in a BMW g20 330e?
We don't have a solution yet.
Is it possible to do this lsd for F30 320i 2013 ?
Yes it sure is.
How much force was used to remove ring in press?
15 tons with preheating to 150°C.
Do you have kit for f30 340i rwd automatic?
Yes we do. That would be 215LW diff type.
racingdiffs.com/collections/lsd-conversion-sets/products/bmw-e46-e90-e92-e39-e60-lsd-conversion-set
@@RacingDiffs hello, same 215LW for the bmw f32 440xi manual?
That would be 188LW diff type.
would this work for 218i f22?
No. Unfortunately, 218i jas 168lw small case diff that we didn't make the lit for.
@RacingDiffs wouldn't it be compatble with 168k lsd?
@dawidkossowski4714 I'm not sure about that.
