ARP vs. Peak Performance vs. CS vs. NISMO Wheel Studs... WHO WINS?

[INeedNewTires]

Hey i'm in the process of installing wheel studs, i've done a bunch of research but i'm having trouble finding specs on the peak and CS wheel studs for my S14. my breakdown is as follows

ARP:

+1) 200,000 PSI tensile strength
-1) only 1.5 thread pitch
-1) $119 just for the front 10, and their not even really made for our cars! but work fine i'm told
+1) only $39 for rear 10 and s13 fronts (damn s13!)
-1) only 10mm longer up front
~0) about 20mm longer in rear (average)

Peak Performance:

PSI tensile strength???
+1) 1.25 thread pitch so no need to buy new lug nuts
+1) only $100 for all 20!
~0) I've heard 60mm is about 20mm longer than stock but i'm not sure, and have not had any confirmation of the fronts vs rears and how much longer than stock they actually are

CS

PSI tensile strength???
+1) 1.25 thread pitch so no need to buy new lug nuts
+1) only $100 for all 20!
~0) I've heard 60mm is about 20mm longer than stock but i'm not sure, and have not had any confirmation of the fronts vs rears and how much longer than stock they actually are.
-1) Dont think their of as high a quality as ARP nor Peak

NISMO-Worst yet

-2) stock strength, just longer (or so i've heard, could be wrong?)
-1) stupid expensive
~0) 60mm..... blah blah blah



So please tell me what you think guys. I will be purchasing them very soon as i am about to do rear Z32 brakes w/ ebrake and know i have to pull the hub to put in longer studs so might as well do it all at the same time. I use the car as a daily driver but do participate mainly in road race and drift on a monthly basis. Of course i will be getting forged open ended studs so that is a moot point. Also, if any of my information is incorrect or parts can be found cheaper PLEASE let me know, As i said i have done some research but obviously dont want to claim to know everything yet, thats why i'm asking you guys for your opinions on the best buy. I want a good value for the dollar etc. etc. Anyone who has used any of these please give me your input. thank you in advance.

OE stud is 42mm. The CS or Peak will be fine for your application. The ARPs are clearly a little better, but more expensive and require the use of new lug nuts, making it even more pricey.

Not true, you can change the studs without removing the hub.

[tknbkthrsdy4anfg]

I have Nismo, the only thing I hate is it takes forever to bottom the lugnut out on the wheel.

[projectRDM]

Not true, you can change the studs without removing the hub.

The 60mm studs are tight though since they're almost an inch longer. 50mm studs go in fine.

[drift freaq]

solution to all of the above www.summitracing.com Moroso or a couple of other quality American brands. much less than any of the stated above.

am i reading this wrong or does ARP actually make 12x1.25 studs, or better yet do these even work for S14? Front seems to fit with Knurl being barely off, what about the rear?

it has to be the right knurl for them to fit, not the thread pitch

[INeedNewTires]

i checked summit racing, the front studs are $57 for 5 of em. that sucks ass! Havent looked into moroso though, will check them out and see whatsup. thanks for the tip

[kouki_s14]

Edited my post, knurl diameter is barely off, but i cant find stock knurl length to compare

[INeedNewTires]

stock front knurl is 14.3mm

just going by memory but isint it 25.4 mm=1 inch?

Stock rear knurl is 13mm

[TheWolf]

I used the peak studs.. just got done installing them. If anything the peak studs's knurl is a little oversize.. they were a PITA to get in but worked fine.

[jsuhs14]

as a personal user of the peak performan studs, i have nothing but great hings to say about the studs. they work extremely well, are longer so if you are runniing a spacer you are able to catch more than a couple threads, its like there is no spacer. this stud is very durable. i have yet to snap one. peak performance FTW!.

[INeedNewTires]

ok after many conversions and math problems i've figured out that the Moroso .560 knurl studs that are 72.89mm long (2 7/8") making them ~31mm longer, not 18, sound like a pretty good candidate. expecially for 11 bucks for a set of 5

"Moroso wheel studs are manufactured from high-grade SAE 8740 steel to withstand shear loads of 190,000 psi." --that sounds really good, ARP quality stuff at a fraction of the price.

so the last conversion that i havent figured yet cause my head hurts is the thread pitch, its listed as

Thread Size: 7/16-20 RH in.

can someone figure this out geez too much math for an evening...

[kouki_s14]

7/16 inches = .4375 inches = 11.1125 mm
20 threads per inch would mean

11.125 X 2 = 22.225

22.225/25.4 ~ 1.1428

so effectively 11.1125 X 1.1428?
not gonna fit 12x1.25 lug nuts
someone correct me if im wrong

[Slidin240Wayz]

S13 info is in the thread.

yes they do , i have them all around on my S13 , paid 40 something per kit , bought some muteki wheel nuts for them , they are awesome , i still have the original package but in my car , will get the part number later

[INeedNewTires]

very good info slidin240ways, just a few questions. Is there a moroso part that will work for rear as well? so i can get just one set of good lug nuts, and 2 which are the brands/retailers that i can get the correct thread pitch for "tuner" lug nuts that are like a nice forged steel with open end?

[INeedNewTires]

My price breakdown:

Moroso front, Arp rear, gorrilla nuts front (closed ended though) , muteki nuts rear = $137

Peak performance studs all around and muteki nuts = $140

ARP all around and muteki nuts = $195

So i've always been a big believer in you get what you pay for and i also would like to have 1 set of nuts in the same thread pitch especially if they were made for the car origionally, so i think i'm leaning towards peak. your thoughts?

[INeedNewTires]

Another couple points i want to add, i have lugcentric spacers as well as both hubcentric wheels, and lugcentric wheels. so changing diameter of the lugs could screw a bunch of stuff up.

The second thing is i really like the "quick start nose" on the moroso product, why doesnt anyone else do that, or am i missing something?

[azndummie]

i got nismo 60mm and they fit basically like oem with the oem quality also.

[bigOdom1]

i just got nismo studs and muteki open ended, yet to be put in but they are in the trunk

[opponheimer]

I got either CS or peak performance studs on ebay and the knurls tore up at the first use, I have to actually hold the back of the stud against the hub to tighten lugnuts, what a pain in the ass.

Wish i got nismo.

If nismo doesn't make longer than 60mm would get ARP if I were you, they know what they're doing, and will back their products 100% Who cares if you have to get new lugnuts, get them..

[INeedNewTires]

opponheimer, not trying to bash or accuse you, but i'd be willing to bet that the knurls tore up due to an installation error, rather than a product malfunction....


did you guys read this thread or what? NISMO is STOCK strength..... which means they will break just as easy as the stock ones, if not easier because their longer. not only break in half but the threads will shear off easier too, this is what i want to avoid, i want something that is going to last a LONG time. I mean shit on one drift event i'll change the rears 6 to 8 times, and the fronts twice! the stock lugs are hating me, plus after so many times of torquing (sp?) and loosening wouldnt they stretch and/or weaken? I even asked a guy at nissan parts and he said they were stock strength, so am i wrong or what?

[projectRDM]

The Nismo studs are supposed to be stronger than OE, but they do indeed break just as easily, I know firsthand. The biggest issue here is proper lug nut installation, you could drop all the money in the World but it only takes one cross threaded nut to sheer a stud clean off, and the longer they are the easier they can break.

[kouki_s14]

and the longer they are the easier they can break.

Not necessarily true, it varies depending on where the lug nut mates with the stud. Spacers(or thicker backing plates on wheels) and longer studs usually means the mating distance is further out, making it less capable of handling the axial loads, thereby making them seem weaker. (think of a piece of string, same material throughout, but you can easily pull it until it breaks when it's a few inches long. If you apply the same amount of strength with a very short piece of string, it wont break nearly as easily)

As for the Peak Performance studs, i sent them an email in hopes of getting some information about tensile strength and material and this is what i got:

Eddie Kim to me

I don't have that information our studs are very close to factory type, but
just longer. They are made in Japan by a reputable wheel company.

Aside from that information, I don't have that kind of information.

Dont know if that helps anyone, but it was worth a shot.

[Xandy Boosts]

How are the ichiba's compared to nismo and stock? I have them installed now but never really researched. They were 2 bucks a pop from the ichiba site

[INeedNewTires]

Yes that helps a TON..... damnit now i dont know what to get! i emailed a guy from phase 2 and he said they were close to ARP but sounds like i got the ol sales pitch.......... fucker....... now i'm stuck and my project is grounded until i get this figured out! shitty...

i had a dude offer me a full set of H&R studs for $50 shipped, are they worth a damn?

arp extra log wheel studs, 12x1.25
they are not made for nissan, but they work and fit perfect
these studs are for a saburu wrx impreza

i have arp on the rear and nismo on the front, s14, i broke a few nismos in the past the arp are a lot better

ARP.

Peak Performance is garbage, I have their tie-rods, they have not even been used (installed on my car on jack-stands) and have surface rust..

@#%k that shit.


How is this even a questions, only one of the above is actually a proven name in fasteners/studs. Nismo does not even make them, nothing but tagging them with their name after farming out the work to god-knows who, as due the other two I'm sure .

[Homer_Simpson]

ARP, its even cheaper now for S14 guys since SPL is selling the front set for $39. That's right, $39.

[articdragon192]

I'm gonna think out loud here, so people bear with me.
ARPs and Morossos are stronger than stock and Nismo. I'm assuming that whatever process made them stronger, has also made them more brittle? Or am is my thinking totally off? If that's the case, won't vibratiosn totally fuck those stronger studs? Because I know of an S2K that has broken ARPs in 3 different occasions all due to not running hubcentric rings. And I'm pretty sure a lot of people here don't run any kind of ring, especially when not hubcentric spacers are being used.
Because of this, I ended up going with the Nismos, which, also not as strong as ARPs, are the perfect knurl size, the correct thread pitch, and less brittle.
Someone correct me if I'm wrong.

[az_240]

I'm pretty sure SPL sells those studs for $80... not $39. If you go to the site and select the 14.3mm knurl it has a +$40 next to it.

Nismos suck... they are basically the same as stock just longer. I broke 3 of them in the front after some hard driving on 18s.. They just crack off one after another on different occasions.

I've never heard of anyone breaking ARPs. The only issues with ARP is the 12x1.5 thread pitch which will need new lug nuts and the knurl sticks out on some hubs.

http://i12.photobucket.com/albums/a229/livinglegendlll/from-the-top-knurl-problem.jpg
These are not ARP studs... im just using this pic I found on another forum as an example. I just installed ARP studs on my OEM hubs and the knurl does stick up past the hub just barely on the rears(less than pictured) making it so the rotor does not sit completely flush with the hub. I plan on using an angled/stepped bit to help make some clearance on the rotor.

In that case, just do what I did and use IS300 ARP studs for the S14's front. 2 years of abuse and no problems.

$26 for package of 5 of the ARP IS300 studs
ARP 100-7715 ARP Wheel Studs (http://www.jegs.com/i/ARP/070/100-7715/10002/-1)

There are other options out there from ARP that has proven to work on the S14 front as well. These ARP studs can also be purchased from Jegs and Summit at similar prices just like the one I listed .

Edit: Aceinhole is using these ARPs from the Lancer Evo VIII on his S14. $29 for a package of 5.
