Offset 101 For Dummies

[SiI40sx]

http://img406.imageshack.us/img406/2783/offsets2fs4.jpg

Too much positive offset will make you hit your coilovers or chassis, the more negative offset you have will make your wheel stick out. Take note that the width of the rim plays a major roll on your offset. The bigger the rim the less room you have to play with offset sizes.

Conversion: 1 INCH = 25.4mm

example: 17x10 rim is 254mm wide (0 offset for that gives you 127mm sticking out and 127mm going in)

Mods sticky this?

Also please feel free to throw in some exact figures in here as far as whats the maximum clearance you have gotten from rim backspace. Thanks!

in regards to offset, i'm truly as noobtastic as they come, so this thread is helpful. thanks much.

Images are very crude but they work fantasmicly. Would suggest a little more info on our cars limits, but I'm not one to talk because I have no clue what they are. +1 for a good thread for the noobs.

Tire stretch also has a lot to do with fitment :D

Your still not that clear, thats why some people don't understand.

Let me help.

Your example for example: 17x10 rim is 254mm wide with a 0 offset means that the offset is dead center, so you have(254/2=127. You have 127mm front and back space. If this same rim was a +35 you would find the center line wich we already did its 127, now add 35(+35) (127+35= 162) now take that away from the total width(254-162=92) so our rim is 92/162 convert that (162/25.4=6.3 and 92/25.4=3.6) your rim is 10" wide with a 6.3" back space.

This is not going to tell you what you can fit unless you know your car, I had a tool that would let me put a car on a jack and check the in and out clearance, but it grew legs. You can also use your stock to do the math on and then mesure from the front to see how it will line up with the fender

[mrpeepers]

I think the original explanation is good enough for me. Call me a cave man but i got it :dunno:

his original picture is fine because it shows the relationship of the coilovers to the rim, very nice, post this in my suspension faq thread please, it's stickied

It can't get much simpler than that. Great write up!

[StaticX27]

That's awesome... Like, for reals.. +1 for you

[xamraci]

Good Write-Up fo sho!

If this gets stickied and people post what fits is more/less flush on certain cars, that would be pretty awesome...Just for a refference...

S14
I rock a +0 17x8 Up front and its WAY FLUSH I have to have a fair ammount of camber because my front tires arent very stretched
I rock a +19 17x9 Out back with 225s and they are JUST stretched enough to clear stock fenders with no trimming, rolling, hammering(also a fair ammount of camber)

I would also assume with the above math you could calculate a good offset per the width of your rim...as in if you were to run a 17x10 out back on an S14 with say a 235 or 245 tire, you could probably run a -5 and it would sit fairly NICE/flush in relation to the fender, if my math is correct and my assumptions of fitment are right...


Good thing about those images is that they help to illustrate Wheel Spacers if you understand the math for wheel spacers...that would be a cool piece to add in some of the diagrams

Good Stuff!

[SiI40sx]

Thanks for the responses. Again let me say that this is a VERY VERY generalized overview of learning offsets. It doesn't go into detail about wheel lip and flushness. The lip of a wheel takes one more extra step to figure out. Notice some of the pics that were posted above? The spokes (face) of the wheel has a certain size also. You need to take that into calculation to figure out flushness....

Next thing we could do is a chart on what clears coilovers and what doesn't.

Width---------------------Offset

6.5 Inch------------------ ????
7 Inch-------------------- ????
7.5 Inch------------------ ????
8 Inch-------------------- ????
8.5 Inch------------------ ????
9 Inch-------------------- ????
9.5 Inch------------------ ????
10 Inch------------------- ????
10.5 Inch----------------- ????

^^ If we can get something like that filled in, that would be the best guide to buying wheels. Again remember, its easy to figure out what will clear coilovers or clear a wheel hitting your chassis. BUT it wont necessary mean the wheel will be flush or be sticking out too much.

THE FRONT (Lip part) OF THE WHEEL IS CALCULATED DIFFERENTLY FROM THE BACK

baller should be stickied even though its been covered 1 billion times

[sultan]

just to let you know, a 17x10 wheel is not 254mm wide so centerline is not 127mm.

you need overall width for centerline and offset measuring, which in the case of a 10" wheel will probably be 11".

and there's no reason to convert to mm until after you subtract centerline from backspace, which would give you the offset. it's pointless to convert backspace, overall width and centerline to mm since most people here are in the US and use inches to measure unless they are just trying to be jdm.

a 10" wide wheel is not 10" physically.

roughly 11" yes.

i measured a 9" wheel, hair under 10".

If your in the wheel business then it is 10" you dont messure a wheel from end to end, you mesure from the seat to seat.
We always use mm... cus engineers and designers never us anything US.. hehe ... only the metric system. This way its the same world wide.

... these are some nice pics you guys are coming up with....
I will use the hell out of these for trainging..

but the point is when you are figuring out offset you do NOT use seat to seat width, you use overall width. if people tried to figure out the offset of their wheels using what people said earlier in the thread it would be wrong. when a wheel size is not marked most sellers of wheels in the US and some in japan (upgarage) do not correctly measure the wheels and you end up with a different offset and width.

and they were talking about converting to mm which is 100% pointless except for offset, not actually measuring in mm. this thread is not about engineers and their fancy metric measuring tools, it's about retarded people on zilvia trying to figure out what size their wheels are.

[Steveohoes]

Great write up!

Definitely needs to be stickied

[Doluck]

This is true, I always just add 12mm to the side im trying to get a tight fitment on. I t would be nice if the width was taken from lip to lip tho.... If someone need to get detailed you would need to messure the wheel by hand.

That is completely irrelevant to this topic.
OP isnt in the wheel business.
You'll HAVE to measure the physical dimensions from lip to lip because ultimately, the seat width doesnt matter for shit when you're fitting the wheels on the car.

[koukimonster139]

Doluck, you're a jackass

we're not talking about how to measure a wheel

we're talking about how to measure the offset of a wheel which is not obtained using the seat width.

[Doluck]

Wow ... you guys are tards.... If you read the whole post you woudl see the relevants.

If you have a 10" wide wheel(254mm) with +35mm offset.(254/2+35=162)(254-162=92) so you cant go thinking that you have 162mm / 92mm, cuz when we tell you specs on a wheel its width is from seat to seat. That 10" wide wheel is really 10.8" or so. You back space is really about 102mm not that 92 you would get from that wheels specs. get it... it was just an fyi. So chill out...

[babowc]

hence our response:
10" wheel is not physically 10", rather nearly 11".

you just reiterated what we said.

[Doluck]

But the offset is that of a 10" wheel. which means you need to add a few mm to you math if you are doing the math for a perfect fit.

[rongfk]

how can you tell the offset from looking at the back of the wheel? what letters are typically used to determin it.

[koukimonster139]

if the wheels are worth a flying fuck there will be a stamping or a sticker showing the size, width, manufacturer, offset, model number etc...

[Doluck]

No its not right... thats what im trying to tell you. if the maker says its a 10" wheel its not, and they say the offset is +35 well its not. Cuz the wheel is really 10.8" and the offset (from lip to lip) would change. The offset # we give is off the width from seat to seat.

my work vs-ss and work emitz have the sizes stamped on them, the ssr d5r's have a sticker.
my amistad type d, no sticker or marking. my old weds kranze cerberus, no sticker or marking. i guess they are not worth a flying fuck then. :(

that is completely wrong. backspace - centerline (based on overall width of course) = offset. i've measured wheels with marked sizes (rota grid off road, work emitz) and my measurements match what is on the wheel. rota said +10, it was +10, work said +0 and -16, it was +0 and -16.

[koukimonster139]

^ thats wierd

my weds kranze cerberus have stickers


guess yours fell off

[Doluck]

I do know Rota do give you the total width.. I found that out when I worked with them awhile ago. Thats why they are one of the brands I carry.
My works, volks,enkei and 99% of the other wheels I have sold have never added up. Rota does it to cut down on weight.

any advice? it appears to have a positive offset, but of what? is the question.

[flclsteve]

What are the pros n cons of having plus or minus offset is it just for looks
or do certian wheels have certian offsets to fit correctly

[firelizard]

So noobie question
What are the pros n cons of having plus or minus offset is it just for looks
or do certian wheels have certian offsets to fit correctly

In a nutshell:

Often a driver will select a wheel with a smaller offset than stock.

A smaller offset will create a scrub radius which may affect the handling of the car, but there are a number of reasons why you may need to choose a smaller offset.

1. To compensate for a wider wheel: A wider wheel with the exact same scrub radius as the stock wheel will be positioned closer to the suspension components. If the wheel is too much wider, it will not fit. To compensate, you would choose a smaller offset to move the wheel away from the suspension.

2. To create a wider stance: By setting the wheels outward, the stance of the car becomes wider and stability is increased. In some applications, the benefits of this stability are greater than the drawbacks of the scrub radius change and the driver may make this compromise.

3. Looks: A smaller offset moves the wheels outward, so they have a tendency to fill out the wheel well better. Cars set up for show, more than performance will often choose a lower offset wheel, however, if the offset is too small the sidewall will rub the inside of the fender.

And as for what "scrub radius" is:
Scrub radius is the distance from the point where the steering axis meets the ground, to the center of the contact patch of the tire. Zero scrub radius is desirable. Increasing the scrub radius will result in more kickback through the steering wheel when you hit bumps and increased steering effort.

Also, lower offset = harder on wheel bearings, so that's something to account for.

[GabeS14]

any advice? it appears to have a positive offset, but of what? is the question.
Is there any other stickers on it?
usually there is a sticker with the size, and next to a a positive or negative number followed by a number(*in smaller letters)
if not then you would need to get it measured,
or check the manufacturers website to see the different offsets they offer and try to guestimate which one you have!

[SSMini]

Hope you guys dont mind me asking a question here rather then starting a new post. I picked up a set of wheels and some coilovers, there not installed yet. I still have to convert to 5 lug. My question is, would I need front spacers if running a 18x8.5 with a +30 off set when using coilovers? If it matters, Im going to be using Rays Gramlights 57F's with Tein Flex coilovers. Rear wheels will be 18x9.5 +20 off set.Thanks...

where do i look?

http://img521.imageshack.us/img521/4522/p1020258yd8.jpg

Most oem wheels are stamped like this.
The offset will be a random spot on either the back of the face, or the front near the bolt holes.

[let5l1de]

this is an example of my rear setup im currently using:
Volk CE28N
18x9.5 +28 offset
265/35/18
negative 2deg camber

http://img.photobucket.com/albums/v295/let5l1de/240sx/IMG_0219_sm.jpg

This rim resembles the 1st illustration on the left showing positive offset. Since the illustrations below are exaggerated a bit to show the differences, it has a curb appearance of the center illustration even tho my rear setup is positive.

http://i64.photobucket.com/albums/h196/swiftdrift/wheel_offset101new.jpg

These are pics from the back of the rim showing coilover to rim clearance. The clearance between the rim and coilover is about 30mm total. (be sure to leave at least 4mm open space for things to move, otherwise you will rub)

http://img.photobucket.com/albums/v295/let5l1de/240sx/IMG_0234_sm.jpg

http://img.photobucket.com/albums/v295/let5l1de/240sx/IMG_0222_sm.jpg

this is how the rear looks with this setup. with minor lip massaging and -2deg. camber adjustment, the wheel tucks without major rubbing.

great thread for people who don't understand offset and wheel fitment. hopefully everyone on zilvia will now have wheels that sit flush.

[sldbyuramg]

great explaination. all of them

[k's_silvia2.0]

Does anyone know if a +38 offset is a good offset?

[MrChow]

^^ Uh??

It isn't? That's high. Go to the fittment thread.

[k's_silvia2.0]

^Just curious thats all.

[firelizard]

Does anyone know if a +38 offset is a good offset?
:ugh:
It's a pretty good one. The curves of the three echo those of the eight, but the incomplete circles of which it is compose draw the eye to the contrasting right angles of the 'plus' sign, traditionally associated with positive feelings.

or you could search

[MrChow]

Oh lol. stock offset is around 40 ish +. Does that help?

[babowc]

I think it'd be alot more useful if we can find out what kind of backspacing clearance we have with STOCK wheels on S13 and S14.

then you can just plug your sizing into a offset calculator on that miata webpage and find it out from there on.

obviously, stock struts and coilovers have different clearances and its all different for every different coilover.

Providing a base of what the clearance would be with ALL stock parts would basically lay a foundation for others to build on, though.

Unfortunately, I dont have any of these informations.

[s13.dark1]

i guess i can learn something new everyday. its simple

[NI_YON_Zenki]

wow, looks like it's gone abit lower or negative than 101

good offset calc. find philvia, I would've never gone further than tirerack or some shit of the same! lol. I just study the books and common knowledge. + I have my wheels. haha.


But, ahem. to keep to the current trend subject. I feel it depends on the complete system of the wheel to determine whether the +38 offset is good for a car, let alone FR, if being placed in the
rear?

I could hear these numbers being thrown around the pits of WRC or SCCA rally.

It might be tight on the inner clearence for the front, what size front over fender? Also what brakes. The rears your going to have to MAKE work with proper camber and tire size.

[jotronic]

Thanks for sharing this info. It was clear enough for an old fart like me:)

[shadow_s13]

Every Nice!!! Thanks. ^_^

[vehicle_5]

Very nice guide. I had no idea about offset before reading this thread. Now all I have to do is study up on camber and tire sizes and then I'll truly grasp the idea of wheel fitment.

[Fastimport]

Conversion: 1 INCH = 25.4mm

example: 17x10 rim is 254mm wide



Not quite.........
When a rim is said to be 10" or 7" wide, that is the width where the tire sets.
Actuall rim width is usually about 1" wider because of the lip thickness.
(aprox. 1/2" per lip)

So a 10" rim is actally 11" wide on the outside.
And this 1/2" will sometimes cause clearance problems with shock bodies, tires, etc..

[beeracing s14]

if there is someone who still cant understand this simple examples... ill hit him in the head.

[DriftCat]

For the life of me I can never keep straight which direction is positive or negative when dealing with offset.

[serah31500]

Sorry guys I couldnt find pics or info with anyone running a setup similar to what I am considering for my stock bodied s13 w/coilovers so I figure I just ask for help. The wheels I am considering are 18x9.5 and 18x10.5 with a -10 offset for all.I am assuming I am going to have to do some pulling/rolling but how much? I tried digging up pics but no luck if anyone can find any that would be great. Thanks guys!

can anyone just tell me what width of rims do i need for them not to rub anything with 0 offset and them being as close as possible on both sides i dont want them sticking out i want them under the fenders their 18'' and on an s13

[240MADNESS]

Very understandable. But i'm addicted to negative offset. Very good thread.

[Import_Prophetz]

BEST POST EVER! This post makes it easier to explain to people what and how offset works. Now I dont even have to talk to them, I just link them here. +1 to you

[713kouki]

if there is someone who still cant understand this simple examples... ill hit him in the head.


i'm sorry i'm still a baby , all i know is that i'm gonna get super advan's 18X9 FRONT 18X10 REAR for my 98 240

if anyone can tell me the exact offsets i need to make them look flush i'll give them a dollar , i have z32 brakes if that matters

[713kouki]

btw my rears are already rolled , and not looking to get overfenders unless needed . thanks for anyhelp

+87 ooutback with a -44 up front with some 33mm spacers all around.

[handinpants]

I have some 17x9 for the front and some 17x9.5 for the rear, the wheels are +12 offset. I am wondering what size rubber to put on there, it is going on an s13 with coilovers, not lowered too much, and i honestly am not good with avoiding the curbage, so i want to stay away from the stretched look, any suggestions, will there be clearance issues?

Until you get into the negative offsets, or single digit offset up front with a 9.5, you're good to go.

Even then, most that you would have to do is either to hammer the fender well, or to pull the front fenders a little bit.

[pornosquadz]

just out of couriosity who knows if the nismo lmgt1 make any of there offset zero or negative??? kuz my lmgt1 are 18x9.5 offset +14(all 4 rims). any suggestions on what size tires and brand should i get???

:sadwavey:So, will a 17x13 -26 front 17x14 -36 rear fix under a s13, with 20mm front and 50mm overfenders?

ur kidding right.....:squint:

i bet you most people would have a TOUGH time fitting 17x13-26 in the rear with bulging 50mm overs....

to put it in persective. i run a 17x9.5 +12 in the front of my s14.... a 17x13 -26 will effective stick out 81mm more.... and dont forget that one needs to turn the wheel for steering..... tubbed fenders would be least of your worries.

to my knowledge they do not come in negative or zero offsets. 18x9.5 in the rear should be pretty simple to fit in the front and rear. roll your fenders and hammer the high spots of your wells.

I would like to get a straight answer, not some asshole trying to a bad ass. If you can't answer someone's question with out being a dick. SHUT THE FUCK UP!!!!!!!!:mephfawk:

[s13 @ fullboost]

answer is no ?

[ARMORY]

Yo! trying to go 5 lug deep and cheap for my s13 thinking about going with china mustang copy's 17x10 +20 all around anybody know if they will clear the coils in the front???

pretty sure rear should be good just iffy on the front looked through this post found it very helpful just need expert input before i buy

thanks sorry for the newbie questions :wan:

Someone on this forum once said "dont ask a stupid question if you dont want a stupid answer" I'm not saying your question is stupid, but why in the hell do you want to run a 17 x 13 in the front in the first place? Trying to be gangSTAR or what? because performance-wise, that makes absolutely 0 sense. So to you answer your questions.. NO, thats just not smart.

I dont know the 13 chassis all that well at all. I've heard of peoples running 10 wide up front, but I'm not exactly sure what the fine details were, theres a gang of info in the "fitment whore" thread you just gotta find it, lol. or search Zilvia. I would think you can do it, maybe with a minor pull? But like I said, thats a pure assumption hahah.

[EndLeSS8]

Do I need extended wheel studs to run a 3mm spacer for the S14 front? Is it safe to run a 3mm spacer on stock wheel studs?

How long are stock S14 wheel studs anyways? I know Nismo has 50mm and 60mm ones, and Peak Performance is 60mm

[need for drift]

Does anyone know if
18x10+30 front and
18x10 +30 rear with a +30 offset will fit s14 chassis
with a stock fenders and with out spacers
thanks :bow::confused:

rears will fit but the fronts won't. you'll need to run a spacer for the front.

"So, will a 17x13 -26 front 17x14 -36 rear fix under a s13, with 20mm front and 50mm overfenders?"

yea, that ant gunna happen. even 10's 10.5 is pushing it in the front of an S13. anything over 12" wide in the rear is pushing it. someone ran 18x13 in the rear with 70mm overs.

[M4J0R T0M]

I have a S14 and I'm thinking about trading for some XXR 521's 18x10 +25 all around. I need to know if they will rub my suspension before I pull the trigger. I'm not a fan of the mexiflush, super poke look and I can't afford overs so I want to avoid spacers.

I used the 1010 calculator and determined that I will have 29mm less inside clearance. Does anybody know what the clearance is with the stock wheels and if I will rub or do I need to crawl under there and measure? I will be running GR2's with Eibach springs.

Any help would be awesome.

Dude, your question is basically answered in the post immediately above yours, except with 5 millimeters difference. So the advice is the same, except your spacer will need to be 5mm less.

Crawl under your car and measure, then convert and calculate, purchase and test fit, then modify (if neccesary), then re-fit. Repeat as needed until you're satisfied.

I see that you quoted my post but you obviously didn't read it. First of all 5mm could be the difference between fitting and not fitting. Secondly, I clearly stated that I don't want spacers. Finally, if I can't afford overs what makes you think that I can afford to buy, and test random sizes without knowing if they fit. That's the whole reason I'm asking the "experts" in here, so I can avoid wasting money on wheels that don't fit.

Thank you for basically not answering my question at all, lol.

Anybody else have any "real" help.


Edited to add: I crawled under the car and did the best I could at measuring the clearance between the OEM wheels and the strut housing. I came up with approximately 21mm, give or take. So it looks like the 18x10 521's wont fit without spacers on the front, w/ shocks and springs.

Again, there is approx. 21mm clearance between factory wheels and susp, hope this helps someone in the future.

[KiLLeR2001]

I'll just leave this here...


W = The wheel's width in inches.
S = The wheel's offset in millimeters.
X = Distance from rotor mounting surface to desired rim location in millimeters.
Y = ((0.5(25.4 * W)) - S)

If X = Y, desired offset is achieved.
If X > Y, rim will be sunken in more than desired by difference of (X - Y).
If X < Y, rim will be poking out more than desired by difference of (Y - X).

[jamrome918]

So I'm planning to get 16x10 -12 offset in the rear for my s13 coupe . And 16x10 -/+0 in the front will it work out or should I get 16x9 on the back and 16x8 in the front let me know I need advice with it

[Bluejayde]

The 16x10's would be hard to fit, probably impossible up front.

16x10
0 off-set up front
- 12 rears

[RZinkand]

Okay, so im as new as they come on tire fitment. im trying to make sense of the diagram. ill make this short and sweet. Will a 17x10 +20 offset (6.29 backspacing) fit on the front of a stock 89' 240 hatchback? and 18x10 +20 offset (6.54 backspacing) fit on back? Fenders are rolled. suspension is stock (for now) how big of a spacer will i need? 20 or 40mm wide fenders?

Thanks again for the help.

[BadIntentionS14]

So I came here and have been reading the whole thread. I recently got a set of TE37's sitting in my buddies garage. They are 18x9+35 and I'm worried they won't fit but I think I could work with them. I have a stock bodied s14 (not even touched fenders and wheel wells) sitting on FA 500 Series Coilovers. I wont be able to try them on for a couple of weeks. Should I get my hopes up on them not rubbing my coils? The Offset is a lil too positive for me but I got them for a steal and I'm running stock SE 16s. Please help wheel fitment noob here.

[derass]

18x9+35 will touch the coilovers in the front. you need +20 offset minimum for about 5mm clearance

[heychris]

17x9 +30 r33's fit no problem on stock S14 with 5 millimeter spacer. Would likely fit without spacer too. As do 16x8(?) +35 z32 wheels.

I'm looking to buy rota D2 wheels in gold.
But the off sets make it hard to desided what to do
I want
17x7.5 in the front
And 17x8.0 in the rear
But seeing that I'm 4x114 bolt pattern the 8.0 wide wheels only come in +35 off set
So I'm going 8.5 in the rear
I guess my questions are
What would be a good offset for the front and rear for best handling no drifting.
And is that a ok staggered size..?
I think I'm going to get set on fire for this.... But oo well I got tuff skin!

[derass]

a staggered setup will promote understeer. i would personally go with the D2's in 17x8.5 +20 all around.

Too much positive offset will make you hit your coilovers or chassis, the more negative offset you have will make your wheel stick out. Take note that the width of the rim plays a major roll on your offset. The bigger the rim the less room you have to play with offset sizes.

Conversion: 1 INCH = 25.4mm

example: 17x10 rim is 254mm wide (0 offset for that gives you 127mm sticking out and 127mm going in)

Mods sticky this?

Also please feel free to throw in some exact figures in here as far as whats the maximum clearance you have gotten from rim backspace. Thanks!
i need help with an offset problem. i have r33 skyline breaks with 5 lug swap on my s13 i want to buy rims that will fit without using spacers. what kind of rim and offset do i need if i can get my hands on r33 rims i would buy them right now.

Wheel to caliper clearance isn't really offset dependent or at least not as much as wheel to strut (coilover) clearance is. You need to look into what style 'face' your wheel has and then compare that with your brakes. Some wheels with good offsets still don't clear Z32/R33 brakes because the backside of the face is the wrong shape.

I am wondering if anyone knows if i try to fit 18x10.5 +20 in the back nd 18x9 +25 in the front will they fit right away will i have to use spacers can anyone help me i need to know before i buy this wheels will they clear my suspension? ThAnx

I would appreciate any input
