18 X 10's Dont Fit....please Help.

[noneedforaname]

Hi all,

Just wondering if anyone could help me with a rather painful problem I have.

I have a 1993 R33 skyline that I had off the road for some time and am just trying to get it driveable to sell to a mate.

My problem is this: I bought 18 x 10's (15mm ofset) off an online store that said 'fits R33'. What they didnt say is 'fits R33 with considerable mods'.

After some research on this site, I see quite a few people have got them to fit, with guard rolling, camber arms and adjustable coilovers.

No worries, I figure I can make this work.

So I buy some coliovers off a forum that apparently came of an R33, but silly me, didnt ask what size wheels they had, and it was that long ago, that I no longer have his details to clarify.

Long story short, yesterday, I roll the rear driver side guard, fit the new (secondhand) coliover, and camber arm, then try fit the wheel. It simply does not fit onto the hub, as it interferes with guard. I tryed raking teh camber in and out, but to no avail.

The tyre is a 255/40/R18.

I then compared the suspension and the adj. coilover is a lot shorter that than the stocky, even when completely maxed out.

Has anyone else had these kinds of dilemnas?

Is it necesary to drop the bottom eye of the shock, fit the wheel to the hub and reassemble? (not very logical I know)

Any help would be greatly appreciated. (and yes I know im retarted, thanks for noticing, hindsight is a real bitch!)

Thanks in advance.

Regards,

Daniel

perfectly normal for them to be shorter. keep in mind that standard strut would compress a fair bit under the weight of the car.

what exactly is it hitting?

[GTSBoy]

Well, yeah maybe the first order of business is to get the strut out of the car, put the wheel onto the hub and see if you can swing the whole lot up under the guard. I would fear that that offset at that width is going to be hard to fit.

The problem here is that it is not feasible to have to drop the strut in order to change a wheel in later use. That's a bullshit outcome.

umm my question is.....is your 33 a GTST or a GTR?

1993 R33 skyline IE GTST

[Duncan]

that's what I was afraid of. 18x10+15 is for a GTR.

I've never tried anything too aggressive on a GTST but the biggest I can think of is stock 33 GTR wheels which are 17x9

[GH05T]

Best feasible option is to sell the wheels and buy a more suitable set. I wouldn't try to put cash into getting them to fit if I wasn't keeping it

[Jap_star]

they will fit. not with a 255 though. and not without some guard work and -3 to -4 rear camber. which doesnt really sound like your thing

And here i am worrying about 18x9.5 +22 with any decent rubber lolz

Get rid of the comically oversized tyres and put some 235/40R18s on there, roll the guards, upper camber arms at full neg camber and all the very best!

[Duncan]

I've never been a real fan of ruining the alignment and running too narrow (stretched) tyres just to fit a wheel.

If you are going to run 235s an 8" wheel is sufficient and will fit much better.

But alas that's what the kids are doing these days!

I assume Daniel is chasing form > function.

hahah see I am getting old. I remember when Time Attack was called a Supersprint, and when Drift was the Next Big Thing and had a national series.

BTW is it also possible that the front shocks are for a GTR? Are they the same as GTST in R33s?

Haha

Besides perhaps some ever so slight differences in lengths and/or valving the GTS-T and GT-R front shocks are the same.

fits easy, i ran 18x10+9 on the rear with a 235 tyre camber arms and rolled guards fronts where 9.5+13 same deal

why would you say it "fits easily" when the wheel you fitted to the front was 1" narrower, and had a dangerously narrow tyre on it?

[alr33x]

it was not dangerously narrow and the front was a 225/45 from memory (while ago now) but its really not hard people have put much larger wheels on 33's the guards are generous with some work i had 0 scrubbing and i would be pretty certain my car was lower than this guys. He hasnt mentioned if its front or rear unless i missed something?

Duncan, only 0.5" narrower

A 235/40R18 is actually a legal tyre size to run on an 18x9.5" wheel here in Australia. By my calculations the 18x10 +15 will stick out only an extra ~5mm than Alex's 18x9.5 +13.

Edit: however if Alex was running a 225 tyre then (in theory) that should give him an extra ~5mm of tyre clearance and then the wheel clearance. Enough to reduce rubbing.

Either way 18x10 is too big for the front of a 33 GTS-T.

[alr33x]

here is how my car sat with the specs i listed - its 4mm difference of outer position between his 10+15 and 9.5+13

i understand he may not want low / cambered etc but thats the only way they are gonna fit.

here is yokohama's opinion on safe tyre sizes for a given rim size. http://www.yokohamatire.com/tires_101/customizing/rim_wheel_width/

that shows the narrowest 45 profile tyre to run on a 10" rim is 255....a long way from 225.

this discussion is kind of like someone saying "the thinner you are, the better you look". It is only true until it becomes dangerous. I have a real issue with people flippantly advising that something "fits fine" when it is downright dangerous.

OP said he has 255/40/18 which yoko show as the narrowest tyre you can run on a 10" rim.
