This is a Nissan 370Z differential getting a new 3.91 gear ratio, Quaife LSD, Z1 performance brace bushings and differential cover. Really nice. Build came out super sweet had to do a lot of adjusting for the new gear ratio, and for the new Quaife Lsd. The original factory shim setup was not compatible with the new set up, this happens. That is why we are ready for anything here in the shop and have all factory Nissan shim stock at our fingertips. #puddymod #autorestoration #370z #370znismo #nismo #shopkitty #shopdog #z1performance #lht #350z #drift
