Ve Diff gears

[GLITRES]

Didnt know if I should have posted this in the VE section, but would like opinons from everybody.
I've got a VE calais 6L (which is for sale, but seeing as there is not interest I might be keeping her )
I'm looking at get an LSD and have found a brand new one with 2.92 diff gears. Is this the noraml/Stock one out of an SS?
Also, would an upgrade to 3.45 or 3.7 diff gears be better?
thanks for any help guys..

yeh youd want anything from 3.45 up 3.9 or 4.11 are very good but fuel consuming
