i have some Z32 rear caliper, rotor, and drum ebrake.

i want to fit them onto my z.

i need R31 hubs to do this, but i live in the USA...SO

do Z31 and R31 hubs interchange? what about S12?

some AU guy HAS to know this

i looked on a couple R31 forums and they use Z31 5 stud hubs in the rear so i'm guessing the 4 stud hubs would be the same too?

thats the thing that got me thinking!

Yeh, I haven't heard of anyone doing that. For that amount of trouble I'd go five stud to solve the wheel availability problem at the same time

I figured it out.

Z31 output flange with 240Z 4 stud stub axle bored 8mm with a spacer to seat the drum ebrake.

i have a bunch of 4 stud wheels wheel availability is a joke...theres so many 4 stud wheels to pick from
