Splines into hub

stagea 29.82mm
gtr 32.65mm

axle thickness

stagea 28.07mm
gtr 30.07mm

swaybars

stagea 19.25mm
gtr 25.60mm

rear brake rotors

stagea 265.05mm
gtr 297.02mm

axle to diff uni joint size

stagea 90.63mm
gtr 98.94mm

ok well i been measuring things up and trying a few ideas and heres my findings

stagea track is wider than the gtr (and gtr axles are about 80mm too short compared to stagea ones)

tried a gtr r32 swaybar on the rear and it DOESN'T fit so thats buggered that idea :whatsthat

well the real good news is i recently got sent a axle to replace to stagea one and found out its heaps fatter and bigger unis etc so i compare to gtr one to the one i got sent and the one i got sent is EXACTLY the right length to fit the stagea with gtr diff which is bloody awesome and a stroke of luck as its actually a GTS4 axle which is same larger size as gtr but just 80mm longer

All of the following have the same size drive shafts (or axles)
S13 (and 180sx), S14, S15, R32, R33, A31, C33. I can't comment on R34, but I suspect they would also be the same.
All of them are the same size (though some may have 6 bolt pattern as opposed to 5 bolt pattern where they join to the diff), except for the GTR models. The GTR has a thicker driveshaft, and as a result a larger spline where it enters the wheel hub.

You don't need to change the diff/subframe etc to use GTR driveshafts. Providing your car has 5 bolt pattern on the driveshafts, the GTR ones will bolt up to your diff. Then the only problem is the spline difference.
I can't comment specifically about stageas, but I would bet my left nut it is going to be the same as the skylines/silvias in the design of the rear hubs.
There are 3 parts to the hub assembly.
The hub carrier (or upright), is the cast iron piece that your suspension arms and struts bolt onto.
The backing plate, contains the drum style parking brake (if your car has one) and acts as a stone guard to the brake rotor
The hub itself, holds the wheel studs, the bearing is contained inside the hub and the spline from the driveshaft is engaged with the hub to transfer power to the wheels.
On all of the above mentioned models, the hub assembly is designed the same way, that is the hub is bolted onto the upright with 4 bolts and the backing plate is sandwiched between the two.

The R33 models and the GTR's use a different method of bolting the suspension arms to the upright, which makes them incompatible unless you want to go swapping your whole rear end out. But, they still both use the same method to bolt the hub itself to the upright, which means that the GTR hub will bolt onto an upright from any of the above mentioned models.
