Nismo GT Pro LSD?
 

I thinking on putting in a bid on the 1.5 way GT Pro but, can't find an answer to a parts # question.

the 1.5 has two part numbers 38420-RSZ15-4B and another 38420-RSZ15-4C. I have been to the JDM site but, can't find out anything specific in the differences. I have a nismo with the factory VLSD if anyone know the difference please let me know.

Thanks in advance

After some research and parts comparison it looks like either the 4C or 4B kit will work with the base model diff and the sport package VLSD. From what I can tell the 4B kit has the new axle stub part number which is compatible with the Sport and base. The 4C shows the axle stub as just the older part number fitting the Nismo/sport. I ordered the 4C kit yesterday because the axle stub parts matched the Nismo stock stubs so crossing my fingers.:eek:

Old thread, but... did it work? I have the same dilemma, I have a G37s coupe so sounds like either could work
Edit: after tooling around, conceptZ tells me the 4C is incompatible and I need the 4B.
