350z/370z = Same Wheel Studs?
 

Anyone know if they use the same stock and/or NISMO stud part number?

I want to order some ARP extended studs, but the ones I plan to order are what everyone uses on the 350z. Looking for confirmation they will also fit my 370z.

Bump...interested as well.

Pretty certain they are, when you buy spacers with replacement studs they are not 370z specific but rather fit all Nissan models.

Being that the same lug nuts were transfered over to my 370Z from my G35....and the G35 used mostly the same parts as the 350Z....I would say yes. The thread and pitch were the same...the diameter was the same....just the lengths between the 350Z/G35 and the 370Z are different.

The 350 studs are not the same as the 370,I have been looking into this for 2 months now and ARP does not make one yet.

The front or the rear studs are the same as the 350, only two are new, the other two has been the same for years. I cant remember if it is the front or rear

I dont think they ever made any for the 350z either, pretty sure a specific generation of WRX STI studs had the perfect knurl length and diameter while maintaining our thread diameter and pitch.

Thats what I was going to buy if they are the same.

Yes the thread pitch and diameter is the same, but you have to pay careful attention to the studs knurl length and diameter where it presses into the hub, this is the most critical part! A different thread would be ok because you can solve that with new lugs!

Probably should have read into that first post about the ARP studs. I do remember something about the knurl length between the threads and the "backstop" of the stud that was an issue. Some people were reporting bolt shearing problems.

Maybe Z1 Motorsports can assist you a little. On their site they show bolts for the 370Z. You can inquire on what brand they are, if anything, maybe they can point you in the right direction:

The NISMO longer studs are the exact same, they both use part number 40222-RS015 and they are both available in 50mm & 60mm applications.

I have the 50mm on my Z and they have worked well with my 20mm H&R spacers for the last 3 years without any issue whatsoever.

You can reference ConceptZ for more info since they carry both 350z & 370z applications:

Hey! i appreciate the info. I am going to order up the STi ones everyone uses on the 350z and check out fitment on my 370z.

We have several options for extended studs at Z1 Motorsports.

Hey phunk did you do the ARP install? The specs look correct (knurl 14.35mm/0.565), aside from being really long (75mm) and PITA to install I think these would work?

I put them in the rear only, and they were a perfect fit. Install required removing the wheel hub/bearing since they were so long. Took 30-40 min per side in a fully equipped shop.

Cool, thanks. Pulling the rear hub is pretty simple as I recall.
