NA vs. NB hubs
 

Okay, so I bought a complete Torsen setup off a '00 and it came with the hubs, so my question is... What is the difference between those hubs and the ones on my '92 other than they are newer.

I read on m.net that it'll move the wheels slightly inboard by about .2". Are they a better design or is the difference not significant and I should sell them?

The hubs or the uprights? From my understanding the hubs are the same, the only difference is that the upright of the NB pushed the track width out 0.20" per side (0.4" total)

Uprights, not hubs. NB rear uprights are slightly wider (~5mm or .020").

Okay, I got them kinda mixed up. I have the hubs and uprights. So other than the uprights increasing the track width by .02" or so, they are identical to my early NA ones?

Yes.

It's 5mm per side wider 10mm overall. Done with the rear upright.
