Hi,

I'm no expert on the matter, but I think a +42 offset might be a little too much unless your rims are less than 7" wide. I just put 18"x8" rims with a +35 offset on mine. This seems to be ideal, as they sit dead level with the guards and also leave enough room behind them for a 4-pot brake calliper upgrade :drooling:

I hope this helps.

Cheers ..... Craig :ddd:

Craig,

Is there any chance of seeing a picture with the 18's fitted? By the by - what tyres are you running?

Marc,

I don't have any pics at the moment, but I could may be take some over the weekend and forward them to you if you want to leave your email.

Rims are 18"x8" Inox1 by Koya Wheels. Tyres are 235/40/18 Falken Ziex 326 all around.

Craig,

Thanks for the offer, there is no rush - next time you have the camera out will do.

does anyone know if you can put the same 17inch wheels on a stagea as the R34 skyline has? ie I have 255/45/ R17 on the back, and 225/45 r17 on the front of my R34, but don't know what the offset of the rims actually is...

Stagea 4wd (like GTR's) doesn't like different diameter tyres (width is irrelevant) front and rear.:D

Like SK said ..... you need to try and keep the aspect ratio of your rims and tyres the same all around. I have just looked into all this myself and I think you might find that the difference in the width of your front and rear tyres, will also mean that the actual diameter of your front and rear wheels will be different. I'm not sure what the formula is that they use to work this out, but if you call into any tyre place and ask, they will be able to tell you..... but this is how you get combinations, such as 225/50/17 on the front and 255/45/17 on the rear - because although the tyres are different sizes (width and profiles), the difference in the profiles actually means that they retain the same aspect ratio.

OK, but that wasn't my main question - will they take the same 17inch rims as were standard on the r34 (ie offset ok?)?

Ian,

I'm not sure what the standard offset is on the R34 rims. Unless somebody else can tell us, you would have to check it yourself. It should be stamped on the inside of the rim - normally on the hub. As long as the offset is around the +30 to +35 mark, then you should be okay - although my tyres are 235s all around and my rims are 18's with a +35 offset, I don't think I could have gone much wider than that with the tyres, without them protruding beyond the guards.

Ian,

The tyre combination you have on your R34 would not be recommended for the STAG. A 255/45R17 has a dia of 661mm, whereas the 225/45R17 has a dia of 634mm. Not ideal for an AWD vehicle. You would need to fit 255/40R17 which has a dia of 636mm.

Standard R34 GTT rims fit on Stageas, no problems:cheers:

Thanks. And I understand the size differences if I get the four wheel drive version (the 'if' is because while the 4 wheel drive means more power to the road without slipping, it also means extra weight!! In the dry, with the 255/45 tires on the back of my r34 gtt, I don't get wheel spin anyway.. :-))

Thinking of getting a stagea for the wife, to match my r34 :-)

Ian

This offset stuff is really confusing to my poor brain.

Found a set of 18 x 8.5 F (+40) and 18 x 9.5 R (+45)

I've just been told by several import tune/wheel guys that have done several skylines and stags over here that i should be able to get the 9 1/2 " rears with a +45 offset on the rear "no problems". It dont make sense to me... R34 GTR rims fit at 18 x 9 (+40)... and with 9.5" the +44 sounds right to compensate for the extra 1/2 an inch... so how come posted above someone has said for +42 offset youd need a less than 7" wide rim???

brainstrain - hate feeling stoopid :)

haha - answered my own query again - seem to be posting before I research a bit lately - sorry.

Got a PM back from j-plus (Jeff) with some info you may all be interested in ... Jeff is a SAU sponsor and importer of Jap rims etc - so I asked him for some info about whether the rim widths I posted above would fit - and got back some useful info on offsets for the wider potentials of rims on Stageas...

BNR34 wheels are 18 x 9 (+30).

Not 100% on the Stagea requirements for aftermarket wheels, but I'll assume because they share so much in common with the R33, fitments required will be almost the same.

Therefore, the wheels you have in mind (18x9.5 +45 rear and 18x8.5 +40 front)won't be the best fit, and the fronts won't clear the brakes.

I would be looking for something like:

F: 18 x 8/8.5 (+32)

R: 18 x 9/9.5 (+35)

Try not to go much higher than +35 for the fronts and high +30's on the rear. Feel free to run anything by me for a second opinion before you buy.

Kind Regards,

Jeff.

Just as a follow up - although BNR34 rims are 9" wide +30 offset they do fit ok on the front... but Jeff is right that the ideal for a range of reasons (handling/wear/etc) would be 8.5" max... but ey - Ill be getting them eventually anyway! :devil:

Also - picked up another useful bit of info... if you are buying rims with the idea to ever be able to put 265 width tyres on - the rims need to be at least 8.5" wide - cant fit 265s to 8" or less wide rims.

Also another tidbit most people would know but Ill post it anyway... the correct tyre combination for 18" rims to keep same rolling diametre and thereby keep Attessa happy when you do want more rubber at the rear is:

265/35R18 at rear = rolling daimatre of 643mm

235/40R18 at front = rolling diametre of 645mm

:D

Adam,

Some info for you and other readers of this string.

I have extracted some info on tyre and rim sizes from the Bible ( The Tyre and Rim Association of Australia - Standards Manual 2004), which may assist.

TYRE SIZE... APPROVED RIM SIZES(inches)

235/40R18... 8, 8.5, 9, 9.5

245/40R18... 8, 8.5, 9, 9.5

255/40R18... 8.5, 9, 9.5, 10

265/40R18... 9, 9.5, 10, 10.5

225/35R18... 7.5, 8, 8.5, 9

235/35R18... 8, 8.5, 9, 9.5

245/35R18... 8, 8.5, 9, 9.5

255/35R18... 8.5, 9, 9.5, 10

265/35R18... 9, 9.5, 10, 10.5

I am probably repeating info which has already been posted - but most states/territories will allow up to +/- 15mm variation to overall diameter in the tyre/rim combination and will allow a maximum of 25mm in track width.

The tricky part is that the fitment may well be legal but to satisfy your insurance company is another issue altogether.

Hope this info is helpful to some readers.

Regards,

Marc2

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
