limited slip differential shims
I have looked around at the price of differential shims on some of the usual websites and I am surprised by the cost.
I was under the impression that the shims were simply machined steel discs. I asked one vendor about this and he said somthing about a special coating. That sounded like bs to me, but I really dont know.
Does anybody have photos of differential shims? Does anyone know what they are made of and if they are a part that is difficult to have made?
Thanks
James

The shop I buy my bearings from gave me a couple of shims for free. Try you local bearing supplier. You can measure the stack with your current shims, then measure your current shim(s) and adjust. Just like setting the valves, only easier.
You don't need to worry too much about OD and ID of the shims. These are low weight parts and are moving at wheel speed (aprox 2200 RPM at 7000 RPM engine speed in 5th)
I see no reason to use shims with special coatings (is ther such a thing?) they are just taking up space. They dont move against anything.

Mark is talking about play adjusting shims. I suppose most other guys are talking about the friction disks.
YES, they wear. Replacing worn ones improve the LSD.
The other trick is to add two disks to the existing 2 to increase locking from 25 to 40%. I guess "how to" is described in earlier threads.

Hey Zambon,
might want to throw your question out to Andy at Performatek:
Since he does do the LSD rebuild and conversion. He ought to know:
