A warning about wheel studs
 

I installed aftermarket wheel studs and spacers to give me +38mm in the rear. I don't want to run staggered, but I like the look of staggered. Anyways I used a kit very similar to this one:

Ebay link

Well after a week I went to retorque my studs just to be safe and a single stud was spinning in the hub. Shit. Either it was broken or the worst nightmare, it rounded off the hub.

Well these cheap chinese studs were not made up to spec and were a hair smaller than the stock ones. I ended up getting two sets of ARP extended studs and they went in without a hitch.

I was able to bang out the shitty ebay studs with a tiny hammer and almost zero force. I probably could have got them out with my bare hands. The ARP studs would take a sledge hammer to remove.

So don't do something stupid and just use no name wheel studs. This is mostly my fault so I wanted to make sure no one runs into this problem as well.

Use Eibach Trak+ or Project KICS spacers, not junk.

H&R not eibach, i agree i might use Ichiba but would rather use either of those 2.

oops my bad. that's embarrassing lol. time to take some holidays.

next up, Tein turbo kits! :bonk:

The classic "You get what you pay for.". Thank You for sharing your experience and hopefully it will save others the same headaches.

Eibach has theirs also in 5mm and 10mm. The 10mm at least include studs, not sure about the 5mm ones. :thumbup:

Currently I use universal Project KICS spacers as needed (ie if I get a flat on the RPF1s and need to use an OEM wheel over the AP calipers).

I also use ARP studs though :)

Damn correcting my correction lol, Trak+ are the H&R ones though.

Wasn't trying to correct really :) Just adding more info.

Just to be clear, the spacers in that ebay link are fine, they are hub-centric and high quality. It doesn't really mater who makes the spacers, just make sure you get hub-centric. Don't skimp on studs.

guessing arp has part numbers for studs for the fr-s?.. or wha

Not all spacers are completely flat. lol .. this is from experience. china has spat out some bad stuff.

to accomodate 38mm spacers - how long were the studs? 70 / 80mm?
anything longer then 50mm, I'd recommend the ARP chromoly studs.
That's a lot of stress on some no-name brand studs.

at least nothing happened while the car was being driven.

Good points right here!

They were 10mm spacers.

ahhh... misread the +38 offset for 38mm spacers.

Does anyone know if ARP sell studs in stock length?

You should bite the bullet and contact them and post the info :thumbsup:

Pretty sure all the ARP stuff is 3" long, or 76mm.

A little too long for me, but have them on my racecar.

Vorschlag Motorports has some 65mm long studs, made in Italy. I have visited their shop (2 miles from my house) and they are going to start building stuff for FRS/BRZs. Their studs don't have the blank starter end like ARP though.

Haven't used them yet but I may put some small spacers on the rear soon.

I know ARP makes studs around stock sizes for Hondas so I'm hoping they do for Subarus. I emailed them but haven't heard back yet.

Should work:

It says 1 inch longer then stock

Sorry, didn't read you wanted shorter ones, ARP's 2013 catalog only lists the 3" length. They didn't have a listing for shorter ones as they do for Honda.

This is correct. They only offer that one Subaru stud.

Did you notice any performance differences with the spacers?

i run ichiba adapters on both my cars daily with no problems

Not yet, this is mostly for visual changes.

I was thinking about getting some myself but wanted to find out which ones were decent first. I imagine pushing it out an extra 20mm or so would really help with the look. I had 2 inch spacers on my Supra, but that was only because runnning 335's.

I'm thinking about 15-20mm in the rear and then I'll be putting 10mm in the front when I get an extra set of ARP studs.

i love to get stuff on ebay but not load bearing parts like wheel studs man. if those break you lose a wheel and flip the car. always go name brand on important stuff.i ran touge factory studs on my s14 they were good

Ichiba sells 40mm and 50mm longer wheels studs. According to a response from IchibaUSA, the 50mm studs are the ones included in the 10mm spacer kit. You can buy the studs individually so I ordered a spare of each size.

I just ordered a 10mm spacer kit for the rear and will add the 40mm studs to the front.

IchibaUSA's website is a little fuzzy on the actual length of the 40mm studs, one sections says 40mm another says 35mm.

Ordered the parts through one of the forum vendors b2autodesigns.com much cheaper than direct with IchibaUSA.

I'll post details when they arrive.

I like ARP stuff, but 3"(76mm) long studs are a bit longer than I want.

Ah crap! IchibaUSA was not correct when they told me the 10mm spacer kit had 50mm studs. The kit includes 40mm studs.

Anyway, the 40mm and 50mm lengths are the actual thread length and don't include the spline area under the head of the stud. For my setup it looks like the 40mm up front and 50mm (w/spacer) out back would have 3mm worth of stud sticking out from the short lugnuts I'm using.

BTW, there was already some corrosion on a couple of the stock studs with the stock closed lug nuts.

any safety concern tracking the snot of a 10mm spacer setup? 15? 20? lets assume the ARO studs are a given. I mean getting silly, almost abusive?

Are you planning to run aftermarket brakes and having clearance issues? Just curious why one would run spacers on a track car.

I have spacers on the the front of my 65 Mustang race car. One does not have the luxury of the exact backspacing on these cars as there are out there for new cars. I have had different brake rotor setups, stock hubs with hats, one piece hubs/rotors, etc, etc. Kinda' expensive to get new wheels every time when you have 10 wheels for the car.

With proper studs, and proper torque there will be no problem. Some of my spacer are 1/8" thick, some are 1/2". You gotta do, what you gotta do.

I have been running 10mm hub centric spacers on my SpecE30 (came with my Kosei K1s from Tire Rack) for 3 years now including about 20 track weekends. I have had zero issues with them.

Project Kics, this is the wheel spacers or lug pattern conversion spacers you should go for. Made in Japan, Quality!!!

You can get some stud length info and issues I ran in to changing out the rear studs to install a 10mm spacer in this DYI post. It didn't go so well. I just updated the second attempt that involves removing the hub.

I don't like the bolt on spacers, as aluminum is holding the additional studs in place, not a steel hub.

The Ichiba studs are no good in my opinion. They don't have enough bite in to the hub. The Vorshlag studs work much better.

Warning to All!

I installed the Ichiba V1 10mm spacer set (SU-50910) with Ichibia 50mm studs (SU-122550), and had to spend a day drilling two of the studs out because their knurl stripped in the hub slot. They stripped when I was torquing the lugs down with the lug wrench using moderate force. The first one slipped then caught, thinking it was just friction on wheel I proceed with the others and then another one slipped much more...leaving me in an "oh crap" moment.

Not only did I have to fight drilling them out, but I scratched my wheel a little, I trashed two studs/lugs, had to purchase replacements, and spent $30 on a set of Rigid Cobalt drill bits. Needless to say this experience has been frustrating, and left me questioning my obsession with always trying to improve my cars function/form (in all seriousness, I'm probably incurable).

I recall reading the stock studs have a knurl diameter of 14.35mm. It's not clear what the knurl diameter of the Ichiba's are, but there's no way they are the 14.30 I've seen them advertised on vendor sites. So in my searching, it seems there are three choices of wheel studs for our cars.

Anyone have experience with the Eibach studs? They have a good selection of lengths.

Mild thread resurrection:

Just fitted some 20mm V1 Ichiba spacers, the included studs are 5mm too short! The fitment with spacer looks great so I don't want to go with a smaller spacer, looks like those Vorshlag are exactly the right length for me. Excellent.

Good choice NissanGuy. I went with the Vorshlag studs and their build quality and fitment are amazing. Highly recommended.
