Help re: WORK wheels
 

Hey guys,

I am a n00b when it comes to all this "offset" business. Can someone please explain to me what the difference is with these:

18 X 7.5 [4-100, 4-114.3, 5-100, 5-114.3 / +38 +47 +53]
18 X 8.5 [5-100, 5-114.3 +30, +38, +47]
18 X 9.5 [5-100, 5-114.3 +12, +20, +30, +38]
18 X 10.5 [5-100, 5-114.3 +23]

Hey mate, I can't really see the link between that info. and helping me solve these digits lol. I know though that I want a "negative" offset (a little at the front, and more at the back).

You absolutely do not want a negative offset on this car.

Read the post in the link that Z86 gave you. Read the whole thing. The information you seek is in there. There's not a shortcut if you want to actually know this stuff. The answer to your (rather vague) question about the differences between those wheel specs is more or less that whole long-ass post.

It'll be worth the time you invest reading it, honestly.

18 refers to the wheels diameter.
7.5 - 10.5 refers to the wheels width
4-100, 4-114.3, 5-100, 5-114.3 refer to the number of bolt holes and their spacing (you need 5-100)
+38, +47 etc etc is the off set, you need something from +38 to +50 depending on your wheel width, and how much "poke" you want.

Personally out of these wheel sizes I'd go with 18x8.5 5x100 +38

Before deciding what width and offset u want for your wheels, u should think about what tyre size you want to run as it would directly effect handling.

I'd work out the tyre size first then determine what wheel width would fit the tyre then work out the offset to determine clearance (both suspension and guard).

If you are focusing on handling, u focus on tyre size but if you are focusing on look then you care more about wheel size then find a tyre that fits.

Cheers mate. I am thinking either the

18" Bridgestone Potenza S-04 Pole Position tyres


or

18" Michelin Pilot Super Sport tyres

18" is the wheel diameter, how about width??

Do u want to run staggered or square? What handling style do u want to achieve? This will determine the tyre width then u think about wheel size.

Also do u prefer look or performance?

I think he prefers to start a thread for every half question that pops into his head instead of doing any research.

Yomchi please do at least a little of your own research (or even just search) before starting yet another thread.

Everyone here is willing to help someone out but you are almost taking the piss now.

Hi Nardi,

Thanks mate! The diameter is the only thing I am undecided on. I want to go a staggered look, similar to this:

http://www.google.com.au/imgres?q=wo...r:9,s:18,i:157

I would like the front to "poke" in a bit, and the rear to "poke" in a little bit more.

I would like both appearance and performance, but I guess they are performance tyres lol.

Panman, FYI, I have spent a few hours trying to find the answers to my questions online. Not to mention, I have emailed half a dozen suppliers... they either haven't responded, or give vague answers. On top of that, JDM concept recommended that I ask my questions on here.

If this is the look you want then the spec is 18x9.5+30 all round. Tyres I think was 225/40/18 front and 245/35/18 rear. Please double check with Leo @ JDM Concept.

Please note u will need some suspension modification to fit, particularly lowering and more negative camber. I'm sure Leo can find out for you.

Be warn tho this setup is quite aggressive. Personally I think this is a more look focused setup than performance focused, particularly if you are not planning to increase power.

Cheers, yeah, I don't want to drop it that low. I think a 1" drop would be more than suitable.

What do you have on your car?

These look better probably... a bit deeper at the rear and the car hasn't been dropped so much.

That's the same size as the group buy I organised.

Which ones?

Ha! Awesome thread..
With respect to tires, so you know how to read that
Let's say 245/35R18
Well 18 means that the tire will fit on a 18" rim
The 245 is the width of the thread in millimeters
35 is the aspect ratio (as in the percentage hight of the side wall with respect to width) so in this case 35%of 245 meaning you will get a side wall of 85.75mm
The R stands for radial, as in the belt orientation of the tire construction (there is more in there than vulcanized rubber ;))
Seriously tho, you could have googled how to read this stuff in like 5 minutes
And be warned, with staggered setup, with directional tires, you will not be able to rotate your wheels left to right side or front to back
I'm not going to get in to choosing right setup for performance, or legalities

Yomchi, also try this website. You can input the specs of the factory wheels/tyres and then the specs of the combination you want to use. It will show you a graphical representation of the wheel and tyre diameters and also show you how the offset changes where the wheel bolts will sit in relation to the centre-line of your wheel.

It will also give you information about how much further your combination will poke out, fill out the fenders or how much closer it is to suspension components.

Pretty handy for learning what adjustments in offset, and tyre/wheel diameters actually does in the real world.

Yomchi I'm not having a major hit at you, and we all have to learn somewhere, but even minimal research would have got you most of the answers.

For example the "will these wheels fit" thread on this website has the answers to all of these questions as well as links to the resources that we've pointed you.

It'd also help if your questions were a little more specific - ie I've heard xxx is good with tyres, wheels, exhausts are all very subjective, if you provide a bit more information as in "I'm interested in Bridgestone potenza RE001, what's everyone's experience" everyone here - me included is happy to help a newb but it won't give you good information unless you are more specific about what you are interested in and what you are trying to achieve.

So apologies for the tone, but try to provide a bit more context for you questions you'll get better answers.

The other point is that all of this stuff is personal.

On the wheel front my personal goals were light as possible, as near to stock offsets as possible.

Why? Reducing rotating mass and not moving it too far outwards so as to preserve power and handling, going to a width that will give me the tyre profile I want.
@Nardi330 @coyote @Nafe

May or may not all have different objectives - going flush, liking a particular brand of wheel (eg. Going JDM on a Japanese car).

Nardi has gone one way, I've gone another, no one is right or wrong - that's one of the things I like about this car (and why it's a Scion in the US not a Toyota) is that it's a great canvas for personalisation.

Decide what your goals are then ask questions that get you there.

ie. I want to have a flush wide look with my wheels, what do you guys recommend?

I won't have an opinion on that - it's not my thing, but a lot of people will.

It's a great community - ask specific questions and people will help.

Ok since we are going in to flush and poke territory, I recommend you read up on Soith Australian regulations on that. I know in qld you can't have any part of the wheel visible outside the car from top down look (or there about, not exact wording). While you might have it for ages, you might run in to a police officer in a bad mood, say the wrong smart ass thing and get a ticket for it
This also includes changing your track
It wasn't a problem in the past as much as it is getting to be now, because more and more people are doing rediculous things (for eg before I never used to see traffic branch doing full car inspections when a road is closed off for RBT, now it's all the time)
And I believe you are after more concave/dish at the rear than front

Yes mate, I reckon just this set-up would be fine that Nardi organised for a group buy:

18x9.5 +38 PCD 5x100

If I am correct, this would give you (x4) wheels with the deeper dish (like the rears on that white BRZ in the picture). Is that right?

Yes but remember u will need other modification to fit and also this setup might not be legal at your state.

@yomchi1989
As @Panman Said, it is very personal. A wide range of sizes/offsets WILL fit, but what do YOU want to achieve.
I, personally, am getting light wheels, with a bit more aggressive width and offset to fill the guard a bit, but still not too aggressive or "hella flush".
There really are alot of these threads on the forum already. Check the wheel forum, you will find a thread with pictures as well as specs.
General rule of thumb - the lower the offset, the more dish/concave look you will have. BUT this also will increase unsprung weight, which in turn affects handling.
What specs am I going to go with? 17x8.5 +35.
Keeps it light, looks a more aggressive, but not too crazy.

Hi Nardi,

If you go 18x8.5 +38 PCD 5x100 (all round) ... would this still be a possible 'legal' issue?

Also, what modifications were you suggesting?

18X8.5 will fit no problem

as to legal stuff, you will need to check regulations with your state department of transport

As Nafe said that size would fit without much issue. there wont be much concave style tho as most wheels require 9" to have concave style. Unfortunately we are not familiar with SA road rules so you will have to check yourself.

I am not familiar with those wheels to tell you of you will get dish from them. Each wheel design is different in dish/concave vs offset and whether or not it changes with said offset

I would personally recommend getting a handle on the car before you modify suspension and tyre setup. I'd also really, really second the recommendation that you look at some stuff on how it'll affect your handling/etc., remember that overtyring this car will make it slower (C&D in the US did a special, in fact, where wider tyres on larger rims slowed it down over better tyres in the stock size).

And yeah, doublecheck with your local RTA. The setup I'm running appears legal externally but I live in a fairly small town so I'll get away with it. The 86? that'll be getting legal wheels and tyres, 17x8" wheels and 225s, not sure on brand yet. If you're looking for dish/lip (increased distance between hub and edge of wheel), just be careful.

Sorry for thread jack, but has anyone powder coated/plasti dipped the stockos black, white, red or any other uniform colour?
I think the stock wheels in black would look awesome, ESP if they have a polished lip (I'm a fan of mat black mulity spokes with polished lips lol)

Here you go.

Page 1 shows them silver, this page shows em black.

cheers man :D thats what i pictured in my head :D
looks heaps better. this is what i would do, 1st thing probably

Hey mate,

JDM concept offer these wheels in 18x8.5+30.

If I am not mistaken, will these concave in more than +38's? (without going to a wide tyre in 9.5).

Cheers

Yes, they will concave more than a +38, but it won't be by much.
I might consider 8.5 +30 as well :)

Hey, u dont need to quote 3 times. When ppl see this thread they will reply.

Anyway what model work wheels you are referring to?

If its CR Kiwami then to have the concave of 9.5" u must run 9.5". The face is the same regardless of offset for each width.

But for some wheels, offset may change the face of the wheel.

They are the Emotion Ultimate.

So, what would you suggest changes with the +30 and +38? Not much?
