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

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

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.

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

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

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 :P

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?

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 :P

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.

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.

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
