do 07+ G's without the sport package have LSD?

 

no i think you need the sport package to get the LSD. absolutely worth it, in my opinion. (of course i got the AWD).

 

You're correct, only the G35 RWD Sports have LSD.

 

+1 - pretty sure the Sport pkg contains the limited slip diff. I think it's worth it too, 300+ HP is definitely enough to cook a single tire I've rotated sideways enough in turns to feel that adding power coming out of a turn is better with two spinning!

 

too bad it isn't a mechanical or clutch type diff,
the viscous type that the sport package has is decent for most, but i want a real diff
wonder if the v35 diff is interchangeable with the v36...
