When I got my X, I wanted the Sports Package for the LSD itself, I figured I could put on Aftermarket Fog Lights and Tow Hooks (the OEM Tow Hook sucks), but when my X was delivered it didn't come with the Sports Package...The LSD is weak on the X's, I had one on my First X, and don't really miss it...but the answer to your question: Yes, get the Sports Package for the LSD itself..even though it's weak, it's a little better than having a Open Diff...
Nissan should really build LSD's on ALL 4x4 Xterra's, instead of getting it through a Package...
