I have been looking specs for stock Z31 hub bolts. Haven't found any.

Have anyone measured those?

Is there direct replacement that actually are same size serration(?) as Z31?

Or if i want to change bolts to new. Do i drill hole little bigger and hammer those Z32 ones in?

Looks like Nismo ones are only Z32 and few other

A - B - C - D - E - Size - Serration

50 - 15 - 10 - 19 - 5 - M12x1.25 - 14.3x36T

s13 studs will work just fine. all you need to make sure of is that the knurl diameter is 13mm.

They are closer to Z31 than those Z32's?


DeleriousZ: (2011-07-17 19:45:53)

those are the correct sizes, but $$$$$. check out circuit sports or ichiba for cheaper ones.

one thing of note with extended studs, the rears can be a pain to do if you haven't pulled the dust shield off, and are trying to replace the studs with the hubs on the car.

Yeah.. little bit cheaper [archived image: smile.png]

But still if anyone have exact measurements on Z31's bolt..


DeleriousZ: (2011-07-18 01:34:26)

a 42.0mm

b 15.4mm

c 7.7mm

d 18.5mm

e 5.5mm

measurements taken off a stock used stud so dims are probably +- 0.3mm

I have the studs that come with Ichiba spacers (say fit 87-96 300ZX or something similar) I had to get my front hubs machined to fit the larger knurl. I don't have access to anything I'd trust to put perpendicular holes in a hub.

That was probably the s14 style (z32 style too??) of stud with the larger knurl diameter. The s13 stud (and s14 rear) is a direct replacement for the z31's stud.

i used some quest studs and i think they were about .5 longer

This is all you need to know. They are everywhere and work no problem

I bought mine from Protuninglab.com. I asked if I could get the ICHIBA 5 lug spacer with studs from the S13 kit and they said they're the same part number. My confidence in ICHIBA and/or Protuninglab is rather low.

I ordered my spacers from tougefactory, and told them it was for a 5 bolt 240sx s13. I could grab the pn off the box of anyone would like, because it was exactly what I needed!

I use 10mm slip ons for for a 350z. As long as its the nissan bore, 66.7mm, everything is gravy.


DeleriousZ: (2011-08-09 04:17:33)

66.1? lol

I didnt remember. Most of the time they either label them 66 or 67mm
