LSD...DOA What to do???

[SMF32s]

Was AXing the GT3 yesterday and in the middle of a run, I started spinning one rear tire and have never done that before. The car was all over the place from that point on. I am pretty sure the LSD let go.

I have an appointment at the dealer tomorrow morning and have a choice to make. I already spoke to them and they are looking into the ability of them paying for the labor and I provide the internals of my choice since it is still under warranty.

Any reccommendations for the best and most robust LSD without killing the bank account. Thanks for your input.
