Cheers

Hi Takz,I took some photos for you to look at this arvo.The second shows the rim with the nuts (cant get a socket in there).The thrid is is from the rear (the tyre sticking out past the guard) And the fourth, i was trying get a shot of the wishbone interfereing with the tyre, but i coudnt get enough light in there Anyway, let us know your thoughts.Cheers heaps!Ps i cant work out the editing of this thing. Its all over the shop.<BR><BR>

tighter tyres, and alot of lowering and all your worries will go away wheel nuts need to be changed. not many mags fit the stock ones in them

Hi INASNT,

I was just wondering how you managed to fit your wheels? I have recently purchased some 18 x 10's, but didnt do enough research and after getting tyres and putting them on, have found out that they stick out way past the guards (1 & 1/2 on the back, 1" on the front) and the front tryre also interferes with the suspension wishbone. I got em off Vision R on ebay, and they were described as

Rota GR6-2R, 18 x 10, 5x114.3 +15, Skyline, Silvia Evo

..................silly me! The stud pattern is about the only thing that fits nicely, and even then i will be forced to get extended wheel nuts as the originals dont have clearance between the rim and nut to fit a socket on.

So......................no its a little late, I thought i had better finally do some research, and i gathered this skyline forum would be the ideal place to make a start. Is there any way i can do to make these work ? Is this even legal in Queensland ?, as i dont think I am allowed to have my wheels 1" & 1/2 out side of my wheel arch (it kind resembles a tractor now, and traction would no longer be a problem haha).

And lastly, if i cannot get these to work, has anyone got a project car going that would be in need of a brand new set of wheels and rubber? They are white, six spokes, Jap looking wheels, and have been coated and cleared with white/silver irradescent pearl, so they look quite nice...................spewing they dont fit!

This is the details i have:

Skyline model = R33 GTST

Wheel diameter = 18"

Wheel width = 10"

Wheel offset = +15 (pretty sure)

Tyre size = 255/40/18

Modifications to fit = ???

Any help would be GREATLY appreciated!

Cheers!

you can make these fit easy

lower the rear and get camber arms with a stretched tyre wont be an issue at all, the fronts grab some camber arms and a smaller tyre and again easy as.

not a big problem at all

[thegreentanya]

Easy eh?..................I like the sounds of that! haha So would TAKZ be correct in recomending the 225s? Where do i purchase these "camber arms" you speak of, what is the going for a front and rear set, and what is invloved in lowering my car? (I must sound like a complete reatrd with all these Q's.....sorry) Thanks in advance for all your help everyone. Cheers

you can probably get away with 235/40, alot of people find 225 too much of a stretch!

lowering can be done several ways but my opinion is to get height adjustable coilovers that way if you havce the flexibility to adjust the height whenever you want, unless you already have coilovers in the car?

don't forget you'll need to get your guards rolled once you lower the car

this isnt entirely true. sure you can roll it up and down...but technically you should get an alignment done every time you move it, as it throws the geometry out (depending on how far you go)

I thought this was easy? Now i gotta get adjustable coilovers to?.........dammit, its all starting to add up haha. So in theory, 235/40's will fit without adjusting my ride height (and adding coilovers), but its gonna look like shit, is that correct? And the camber arms? Will that solve my front wishbone interference problem, or will smaller dia tyres do the trick? And what happens if i dont get the camber arms? Does that mean i will be running negative camber and chewing through tires (and money)?

Cheers

[boiracer]

well coilovers arent much more than just getting lowered springs done with shocks, and very easy to do yourself. without lowering it will look gayer than aids, so thats something you need to take into consideration. and you will need to get it aligned then anyways, so throw them in, put em at the height you want then get them aligned.

as for the camber arms and issues, not sure man, you might just be right with the smaller tires, suspension does roll in to negative camber naturally as you lower it.but coilovers or lowered springs is a must (coilovers for adjustability whould be the best way to go.)

just thought i would add a few pics to show people where the maximum rim size/offset lies for not having to run camber to make wheels fit and still being flush with 'unpumped' guards on the rear.

So this is the rear of my R33 GTST. I have 18x9.5 rims with +38 offset. (Starcorp Racing Impuls- deep dish option) with 275/35/18 tyres on them.

This car is lowered on BC coilovers and running .5 degrees camber (i needed adjustable camber arms to achieve this after lowering the car. On standard arms the most i could get to was about 1.2 degrees).

As you can see these sit dead level with the guards with these rims n tyres. I did have to cut out the guard lip but did not 'pump' the guards at all.

Just thought this might be a good reference point for those wondering what the maximum fitment was in this ballpark without having to run camber or pumping guards.

Cheers

Justin

P.S. i won't comment on the front fitment of the Starcorp impuls as they do not sit flush with the guards (are a 18x8.5 +38)- they sit inside the guards. But what i do know is that they do not rub in any way shape or form with a 235/35/18 tyre and on lowered suspension.

needs moar camber and less balloon tires in my opinion.

cool wheels tho, look nice on the black car

[jjman]

nah i prefer to actually get power down as opposed to going for the cambered, stretched tyre look

n with the front wheels sitting inside the guards n the rears sitting out where they are with no camber n the big tyres gives it a drag car look. Im happy with that

18 x 9 +15 (fronts) and 18 x 10 +15 (rears) - pictures as promised

[thegreentanya]

Just wondering why your wheels arnt sticking out past the gaurd in the rear like mine. I have the same offset etc on the rear. Is it because its lowered with camber arms?? Cheers.

Looks nice!!! What size tyres?

Also why does your front bumper look bent?

I believe front is genuine/replica GTR item 'massaged' to fit a GTST.

Easy answer to that one - I had the rears flared and pumped out another 40 mm. I'm also running camber (-2.2 degrees) which I will be getting readjusted as that's a bit aggressive. I was just playing around with the camber settings and started off with 2.2 - I'll most likely be running -1.8 degrees which will sit just a little out from flush.

Oh and sorry, I am running after market camber arms (I think the brand is "hardrace") which I bought from Just Jap in Kirrawee. The reviews for that brand were good so I decided to go with them.

Tyres I'm running are 235/40/18s for the rear and 225/40/18s for the fronts.

Hahaha...good eye mate! Yeah it is slightly bent and malformed at the bottom of the bumper. The car came with this front bumper when I originally bought it from Kujotk who is (i think) still an active member on SAU. And unfortunately, it isn't a genuine GTR item as Nav suggested - it is a fibreglass bar that was designed as a replacement front bar for a GTR. When it was fitted on the car, it was a little too wide and so after a few driveway scrapes it started to produce the bend that you can see.

On the wings is a replacement bar and possibly a respray so at this stage I will just run it until it's time to get the respray done.

And tyre size question answered on my previous post.

Hey All,

i have spent the last 45 mins going through all 78 pages of this thread lol and i cannot find any obvious combos with these sizes

I am looking to put these on my R33 GTST which has full height adj suspension but nothing else. I would like to avoid rolling the guards if I can but will if i have to.

19x9 +38

19x9.5 +45

Any feedback would be greatly appreciated.

[jjman]

yeah that should fit no worries as long as you dont intend to dump it 'hektic styles'.

Tho im more thinking in terms of 18's so im not sure how much of a difference 19's would make.

At stock ride height my 33 gtst took 18x9.5's +36 with 265/35/18's on and didnt touch the rear guards. (did when lowered tho)

All things being equal tho. Be open to needing to cut/roll ur rear guard. Its no big issue if done right and offset never looks quite right unless the tyre is in the range of rubbing where that rear guard/lip is...
