I have a 2007 nissan 350zHR its a base model, it doesn't have the lsd(the button on the left of the steering wheel)right? A friend sells me the diff can i install it? And will it work? Any modifications? What would i also need!?

 

I had a 2006 before and it was the loaded one it did have the button left of the steering wheel, when id hit a curve at excessive speeds it would help me out. Thats what i want in my HR. can it be done.?
