Well i was bored recently and did some research on the obx lsd. I stumbled onto the neon forums which quite a few members seem to be running the lsd with great success.
They have taken apart the lsd and found that the bellevilles (spring washers) were cracked on a arrival or would crack soon after. So all they do is replace the washers, some people also replaced the bolts which hold the lsd together.
There are people on the forums selling new better washers for about 15$
There is a member on the forum with 18k miles on his obx

They work, but they have minor issues.

Issues are:
Case bolts sometimes arent torqued down all the way.
Snap ring on axle needs to be removed OR bevel the edges inside the diff to allow use of snap rings (recommended)
Possible broken spring washers (1-2 known cases) replacements are avail from a guy here on the org
And 1 guy didnt ahve the axle splines machined into his.. lol

But I do have one in my autoX car, soo to be boosted car. It works good.
