I've gotten a few pm's asking about these rears on the first gens so I think I'll just put a quick reference to what is different first gen vs 2nd here for those 1st gen guys who are looking at this group buy.
second gens will only need the caliper pads and rotors, otherwise the rear is just a bolt on. the backing plates would need to be trimmed as well for clearance of the larger rotor
first gens, in addition to these things will also need to replace the 2 rear knuckles/spindles from an fx50. 1st gens will also require an adapter kit to fit the fx50 rear knuckle/spindle to the 1st gens. I have a limited number of these kits available & the kit is ~$85 plus shipping for this. kit includes 2 upper ball joint adapters and 8 longer hub bolts. you will need the rear spindles and my adapter kit to bolt these on a first gen. my kit does NOT include the fx50 rear knuckle/spindles themselves, just the adapters & the bolts, you would still need to source these rear knuckle/spindles from infiniti.
Thx for the info turbocad, interested in doing this so may be ordering the adapter kit from you. By any chance, do you know how much the rear knuckels/spindles will run...just looking for a ballpark figure? appreciate your help bro...
