im changing to 3.46 ring and pinion from a 318 euro car, i also rebuilt the LSD with 3 clutch pack upgrade from Thayermotorsport which wasnt very hard at all. Changing the bearings on the pinion has been a bastard. But if the E36 diff is like the E46 diff i can post some pics of, didnt want to high jack the thread with non relevant material

I did a custom zf 210mm 30/60 ramp with them. They now developed a new 30/30 45/45 and 30/60 pressure ring which I would love to get if lsd they built for me ever freaks breaks.

If you don't mind, can you please document/write up your process? Would love to eventually give this a shot myself and put together a very formal DIY. But we'll see.

Is rebuilding the stock diff with the racingdiffs kit a worthwhile improvement?

Based on my conversation with racingdiff it seems that they've really came up with a solution to eliminate the faults (noises & free play in right drive shaft) in the original LSD unit. You would have to purchase their clutch pack, bearing/oil seal kit, and preload shim. I was hoping we can get some feedback from whomever had given their products a try.

Sounds good, let me get this thing out this summer and look at that option more seriously next winter.
Thanks
