Wondering if anyone has tried this limited slip setup? I want posi so bad in this car, but the usual options are sooo expensive! Anyone tried these guys from Serbia?

I have no experience with these guys. But another route is to get a '95 3.15 and install a E46 m3 Lsd unit inside and just reuse the 3.15 ring.

This looks interesting, any way to link to the group buy?
I am just a bit concerned of the quality of those, I mean that's like 1/4 the price of a quaife. Maybe my concerns are unjustified but it seems to good to be true lol

Friend of mine has fitted E92 M3 LSD diff into his 750i years ago. As far as I was told it was almost straight swap.
So all you need is a open 3.15 diff from the 95 740 and the e46 m3 lsd and your good?

To install this kit it requires machining some material off the spider gears and off the axles. Its a small amount of material, but requires machining which adds cost.

Anyone have an idea where the "racingdiffs" product is made?
The ebay listing makes no mention of machining need to make the new diff fit.
(To be clear, I don’t know anything about limited slip “LSD” or open differentials). John, you are talking about removing the internals or guts of the e46 M3 3.62 LSD and installing those parts in the carrier of the 95 740 3.15 open differential?[IMG]https://uploads.tapatalk-cdn.com/20190404/6d323c7955f27d7cd70e00278b6008e6.jpg[/IMG]

Okay, to my understanding at this current time, to produce a custom limited-slip differential “LSD” for my 01 e38 sport shorty, you first need the 3.15 open differential carrier from the e38 1995 740i/iL chassis and the e46 2000-06 M3 3.62 LSD (my LSD is from a 2003 M3 donor).
From here this is what gets confusing and probably why more than likely I will not tackle this job myself and it to the professionals to do the actual job. From the information on the BMW forums, the internals, or the “guts” of the M3 3.62 LSD needs to be removed from the M3 carrier, and eventually be placed inside the carrier from the (1995 only) 3.15 open differential that goes into the e38 only, once the internals from the open differential is removed and disregarded.
Can anyone give me any other tips or suggestions on how this would be done? -Ryan

I must have missed this on along the way. I have a 3.15 ready to go in as soon as I get the stage 4 Dinan engine and trans tune. Maybe I'll take the diff that comes out and try to modify it. I know with some cutting and welding an e39 M5 diff and be installed. For now I'm going to complete my winter upgrades and get back on the track.
