5 Stud Hub Conversion

Don't know about the Z31 front. I think I read on clubs12 it does but I've never looked into it.

i'am sure it does, kennyboy on hear would confirm this, his mate wayne scofield from chip wizards, he had a notch back fj20 s12, that was 5 stud front and rear, i think that he used z31 stuff.

I've got a complete rear beam with 5 stud trailing arms and front hubs FS

How much mate to give me an idea?

Hi guys quick bump as I have some issues and reflections. Having done the Z31 rear and a mis-mash of S13 and S14 front & BC Coilovers I'm come to the conclusion that it's more trouble than it's worth. With S13 lower arms I had nearly 4' -ve camber with the BC top mounts maxxed out. With them set at their zero point it was 7' -ve. I'd estimate 10' -ve set fully negative (which would have been fun to see).
There was something like 70mm difference in track, with the front being the wider.

With S12 LCAs I have < 2' -ve one side and 3' -ve the other as a minimum, which I've put down to moody replacement arms or balljoints.
With the S12LCAs and 20mm spacers on the rear the track difference is down to about 20mm IIRC.

Also the wheel arches barely contain the front wheels, even with "weak" OEM S14 wheels. The rears look about normal but, with the front track exaggerated, they look lost in the arch. None of which is the end of the world but I wanted my car to be right. I imagine as a drifter it would work, though.
If I had to keep the coilover set-up I'd either try to find shorter-than-S12 arms, like R31 skyline, or elongate the lower arm -> subframe holes 10mm or so and shunt the arm mounts further in, same as the camber adjusters on S-type jags.

I'm either gonna sell the car as a unfinished project or sell the coilovers and S14 hubs and revert to stock hub/leg. That means trying to find either Z31 front, which I hope will work but not common, or OEM S12 which will fit but don't actually appear to exist anywhere....

never seen the point in the 5 stud conversion myself.my car handled and breaked fantastic on std size grooved discs and decent pads. the suspension was just koni direct replacement with custom 35mm lowering springs and 15x8 and 15x9 wheels

like you say. sounds like more trouble than its worth.

i've done it because i got the early z31 with the 304mm vented rear discs and the z31 arms sit 10mm further out,then i don't have to depend on spacers, i'll just get some wheels made up from image to fill up the gp arches.
