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.

Here's a good DIY for replacing rear studs in case someone needs it:

That method works well except when the studs are 3" long. :) Hub has to be removed as there isn't enough clearance to feed them through from behind.

Did I miss a post? I thought we were talking about 50-60mm studs for 20mm spacers. 3" studs...HOLY! What would one be installing with those...45mm spacers? :eek:

It's the only length ARP makes in that size unfortunately. They are some of the strongest studs out there and recommended for racing applications. I could go with a 1.5mm pitch instead of 1.25mm but then I wouldn't be able to use the stock wheels on the street anymore as I wouldn't be able to find nuts to use.

you wont be able to use stock lugs anyway because they are not open ended. unless you pack a massive spacer behind the stock wheels, probably need at least 20mm but i would just guess 25+

the 3" long studs are not all THAT long anyway. with 15mm spacers and 48mm open ended lug nuts, the studs do not come out past the lugs, they are in at least a few MM. without the spacers, only just the round tip of the ARP lugs stuck out past the lugs.

i suppose if you used shorty lugs, they might look a tad long.

i would assume they are so long to support use of drag racing wheels. not all drag wheels need such long studs, but the set i have are probably 1.5" thick hubs and without studs this long i could never use them.

I need about an extra 15mm for the Forgestar wheels, current have 55mm studs on there. With those the stock lugs still just fit with the stock wheels (without a spacer) but I have a 2nd set I converted to open lug in case I need it.

What length studs are needed for 25 mm spacers?

For stock wheels? 65mm would give you stock thread exposure, you can go up to 75mm as there is extra room in the top of the stock lug.

Yes, stock sport wheels. Thanks ChrisSlicks. =)

We now have ARP wheel studs in addition to our standard and Nismo wheel studs.
The APR studs can be found Here.

We also have open ended lug nuts so that you can run the extended studs without worrying about bottoming out. They can be found Here.

The ARP studs are probably the best studs out there, just wish they came in more than 1 size for the 12x1.25 pitch. Got my Nismo studs from Z1, they ship super fast and have good customer service.

i might have read over it..... but how long are the stock studs on 370z?
it would be nice if i could go measure but i have a 350z, trying to figure something out
thank you

(looking for stock length)

I believe stock is 40mm for a 370Z. The Nismo replacements come in 50mm and 60mm. The 50mm will work with the stock wheels, the 60mm will be too long without a spacer.

Not sure what the stud length is for the 350Z.
