I recently acquired a 13' Nismo diff with 3.69 gearing & factory vlsd; it's a direct bolt.
The stub shafts came with it & everything went right together.
No launching in 1st gear/unless rubber is heated at the dragstrip; cause once they break loose in 1st,2nd is immediately on the redline & then you're shifting to 3rd (still drifting) & then it will finally catch traction & bark the tire's going into 4th!
Couldn't imagine going lower than those,,,as mine came with the factory 3.357 gear's-but i did add a Quaife helical locker for better traction.
Phone Z1 Motorsport's & they can guide you on what you would need to perform this swap.
my rpm's at 75mph went from 2550 to 2800 cruising...fuel milage 25mpg+ on last 400mi. road trip cruising 65-75 (pending speed limit)
Good-Luck!
