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?

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
adamvann3: (2011-08-09 21:47:54)
I didnt remember. Most of the time they either label them 66 or 67mm
