Bolt Pattern, Wheel Hubs and Studs
 

Anyone have any more information/facts on this yet. From what has been mostly gathered in the other thread, it seems to be 5x100.

But what about the center bore, will it be Subaru's typical 56.1mm, or Toyota's 54.1mm? Will the studs be Subaru's M12x1.25, or Toyota's M12x1.5? Will the lug nuts be Toyota-style shank nuts with a washer, or Subaru-style?

None of this really matters of course, but it would be nice to know if other Toyota/TRD wheels will fit the car.

It's hard to say whether or not Toyota/Subaru will even use the same hubs for both models. I mean they're built at the same factory and Subaru did a lot of the drivetrain (minus the transmission and differential, which appear to be more Toyota based), so they may end up all being the same. But on the other hand, they do things like this all the time, I mean even between countries and models, like the Corolla in North America is 5x100, but in most other countries the same models are equipped with 5x114.3, and on the Matrix the 1.8L models use 5x100, but the 2.4L models use 5x114.3, and they're built on the same line in Canada.

I guess what I'm saying is it's totally possible for them (and probably not that cost prohibitive) to put different hubs on different models, however it seems unlikely, especially given that all of the shown production models seem to have the same wheels.

Just trying to stimulate some conversation and speculation. This website is like at least 60% speculation anyways (that number may have been reduced with the added whining since the cars' official launch, haha).

Jeff

I'd say stop speculating and just wait

Actually I am interested in this as well...I am planning on ordering some works or volks and would like them ready around the time the car releases. So knowing the lug pattern and bores would be helpful.

Anyone have this info yet?

:search:


The speculations have been running rampant if you'd do some digging and reading there is information all over, is any of it 100%? Nope because the car isn't even 100% avail. to gauge those things.

It's 5X100 (we know that)

Confirmation won't come until the cars are released. Based on them all having the same wheels (at least in models shown), it seems probably they'll all have the same centre bores.

It will be interesting to see how it all plays out, but my bet is on it using Subaru centre bore and lug nuts. I'm not sure why, but just from looking at the lug nuts, they don't like like Toyota nuts to me.

Of course this is all based on pre-production models anyways, things can change in final production. One would hope not, since Greddy and the like are already making BBK's for them, which would of course be different if the centre bore changed (for the rotors).

Waiting is probably all that can be done. Even if you did measure one of the cars now, there is the possibility it could change (however unlikely that is).

Jeff

I'm interested in this as well. I work for a company that sells aftermarket Subaru parts, so I'd like to have some things lined up for the car before they hit the shores.

I like your way of thinking....

I know a few BMW specific sites did "packages" of OEM parts (they didn't hide the fact) but they made packages up and sold them to people instead of people having to hunt for the parts 1 convenience

Also, in the US the WRXs use a 5x100 and the STis use a 5x114, so the base FR-S/BRZ may have 5x100 but they may use a 5x114 for the STi or TRD editions.


note: 2004 STis are an exception with a 5x100 bolt patern.

yet more speculation ..I could say it is 6X155 or some craziness...no one is 100% sure until it is in black and white

we should petition them to not even consider 5x100 and just give us 5x114.3

shit, I'd take 4x100 over 5x100...

Yeah good luck with that

I have a feeling that first year owners are going to be 2004 wrx'd with the wheel bolt pattern. Idk why, but I hope not. I hope they release them 5X114.3

Good point. We should reserve all discussion on this topic until the car is released and we know for sure. Then the moderators can just replace the original post with the figures from the actual car and delete everything else.

Do you mean 2004 STi'd? Because all WRXs have been and still are 5x100.

no, he meant the first production year FRS/BRZ are going to have the same 5x100 PCD as the WRX (which is 5x100 also).

Then Snoopy didn't need to write the yr. Yr makes it confusing, cuz til '04 STi were 5x100

What I meant is, I hope Toyobaru doesn't make it 5X100 the first year or the second like Subaru did with the WRX or the STI. Not sure which ones right now. But you guys get what I mean :)

Nope, don't know what you mean.

Mainly because you said Wrx "or" Sti.

02-current Wrx are 5x100
04 Sti only is 5x100
05-current Sti is 5x114.3

I'm 100% sure this car will be 5x100 on release, it's way too late in production to change a critical part of the drivetrain.

Except it's not even a critical part, and would probably actually be really easy for them to change on a whim. I don't think they will, I'm just saying it would take very little effort for a manufacturer to do.

Jeff

Yes it is critical. Its less than a year from release, manufacturing has bidded and ordered the hubs for the car. The wheel manufacturer has already made expensive molds for the wheels. There are no good reasons/incentive for Toyobaru to switch to 5x114.3 now.
I've had to live with a 5x100 since 2006 when I bought my 2004 sti. And since then, there has been many more wheel options that have been available. And the FR-S/BRZ could be that push to get more manufacturers involved. 5x100 is more common than people think: VW, Toyota, Subaru (just 3 LARGE volume automakers!).

Some interesting info on this from Toyota Japan's website.

www2.toyota.co.jp/toyotajp/faq/entry/9129.php

Stock sizes:
17x7, 16x6.5
5x100 +48mm offset
Hub bore: 56mm (Same as other Subaru 5x100 hubs :(, expected)

Jeff

Not to mention Enkei RPF1/PF01, Oz Alleggerita, etc.

Not to mention that Rotas are a pretty invalid argument... But Okay, I won't start on that subject :)

A wheel is a wheel is a wheel.

Nothing, but the larger center bore means no other Toyota 5x100 wheels will fit, that's all.

It's not a big deal, I was just mentioning it.

Jeff

If you really want to run Toyota wheels, just take them to a machine shop and have the center bore enlarged. It would be a hell of a lot cheaper than buying new wheels.

Thanks for the info. Looks like I will be able to wrap my current summer wheels in Blizzaks and make them winter wheels.

I know, but honestly have I have witnessed IN PERSON 3 cases of Rota failures on track. I'm not a hater or anything, I just wouldn't use these wheels on anything too extreme. I've had Works on my rx7 and hit a 2 1/2" high "road patch" @ 140 km/h... blew up both front tires, wheels were bent but didn't crack/shattered/kill me and were very easily repaired. I guess you have to see it aka live it, to beleive it.

AS I SAID, LETS NOT START ON THAT SUBJECT :)

I live in Montreal, Canada... that could explain why you DO NOT get rotas here lol... Honestly, i've traveled quite a lot, and we have the worst roads ever, right after bagdad.

Thats an highway exit :

ROTAs are heavy and strong, and of course cheap! not a bad wheel if you are on a budget! :)
