you can't call yourself a suspension guy without understanding how crucial a proper LSD is to handling. A suspension should be designed in conjunction with an LSD - you can't separate them when you think about it. Consider in-turn power application as a result of the LSD and designing a suspension to properly distribute loads generated by the aforementioned.

So, from your lack of discussion on the subject, I am assuming that this does not affect the final drive ratio of the differential. Is that correct?
I have a 2.81:1 pumpkin lying on the floor of my garage. Anyone know of a service to swap the guts out with the OS Giken LSD and a set of either 3.15:1 or 2.93:1 gears?
Thanks,
-Burt
final drive does not change... but you really need to use the larger ratios for the LSD to fit perfectly.
i just drove from NJ to AZ, at a very brisk pace. I put the diff to work on black ice in tennesee (at around 85mph) and then on the crazy arizona desert roads from payson to phoenix if anyone knows that route. this diff is seriously incredible, completely transmormed my E39

So it sounds like I'd have to put the 2.81 on my wagon, while I sent out the 3.15 for the LSD swap. That is doable. Back to the original question.
Does anyone know of a shop or service where I could send my diff to have it converted to the LSD described in this thread?
Thanks!
-Burt
burt - i could do it for you, geoff@full-race.com is my email if youd like to discuss

Awesome write up Geoff! This will be my next mod for sure, when I get the funds together.
thanks for the props, you wont be disappointed!! every day i drive my bimmer im grinning from ear to ear.

Resurrection. Saw an ad for OS Giken lsd's and it listed E39 which led me to their site and now to this thread. Damn, no 540i listed though! This thread wasn't totally conclusive on the fitment though (about using the M5 version), is it not possible at all or just not cost effective because so much needs to be switched out? Seems odd to me that the car in the E39 range that really needs an LSD the most (in my opinion) is the 540i and they don't offer one!
After driving in my 2nd winter with the E39 540i, after two E34's with limited slip diffs, it is seriously pissing me off trying to power out of any corners.
Very interesting mod and great write up. I would love to do this but $1700 for a LSD in a $10k car makes me pause. I'll probably eventually do it.
ill find out the answer to that shortly for you, it was raining here in Phoenix this weekend and i was sliding my e39 around sooo much fun with this diff.
i may end up machining some aluminum solid subframe bushings and reinforce the diff mount so i can get a little more into it, i could feel the rear subframe squirming a little and my car is barely making any power right now.
the diff is worth every penny. The fact that you can pick these cars up for 10k is a bargain, ive owned so many cars in the past 10 years ive lost count .. and the E39 is by far my favorite sedan. Modding it just makes it better and better

from OS Giken - If you want to be sure and you have an OEM diff from that chassis you can measure, then you can compare it to this sheet to determine compatibility.(BMW-L1 type attached; this is what fits to E39 M5 and E46 M3. part# BM237-HA)
email attachment showing BMW L1 type dimensions, if someone can measure their 540i diff i can tell you for sure
does anyone know if the E46 M3 diff is the same center as the 540i?

The chassis must always be regarded as a means to an end and never as an end itself
After owning several cars and trucks with LSD's, I know the 525i I'm picking up tomorrow is going to piss me off sometimes, not having it. It's one of those things, not just on the track, but in everyday driving, that you miss a lot when you get into something with out it.
This will be my first go-around with a BMW product, and so far I have to say the prices on stuff like this have not been as pricey as the stereotypes/assumptions people make....except for this. $1700? Wow...seems like a lot of money for an LSD. Then again the last one I bought and installed myself was an Auburn for my '64 Chevelle. It was about $400.00. Of course, that was over 14 years ago.
Excellent write-up with great pictures. I'll have to keep this in mind.
i just tested my race car out yesterday for a big race coming up this weekend. again i can not stress how important a diff like this is!!

Geoff - great write up! You did not check the backlash on the R&P after switching the diff, I have not looked at the shop manual yet but I presume you found this was not required?
I would really, really like to do this to my 540i M-Sport (with the lower ratio rear). I miss having a limited slip just about every day. This is one way to reduce the intrusiveness of the traction control I suspect
Good luck with the racecar!
Chris
I was wondering the same. Just a couple of thousandths off and it's major gear whine time. I assumed it was checked and by the luck of the draw it was perfect.Geoff - great write up!
