thanks alot roman.

i would recommend anyone who has modifications on their car to print this out and keep a spare copy in the car, and get very familar with it.

p.s i would recommend SAU do something like sticky these sort of important documents.

i also wanted to raise a important question about the document.

this was taken from section 8 in regards to wheel sizes.

88655027sj6.th.jpg

it states that wheels are determined illegal is they are above 25mm from the wheel spesified on the car OR car series.

what does vicroads clasify as series?

Series of the Actual car (eg R34 GTR or GTT or GT)

or

Skyline series? (R32 R33 R34) would that include the new R35 then?

if so R32s (which came with 15s) could have wheels as big as 20x10 and be legal?

Personally i always thought of it as

Brand = Nissan

Make = Skyline

Series = R32/R33/R34/R35

Model = GTR/GTT/GTST/GT

discuss

think about WHY they have these rules and that should help you find an answer. vicroads' rationale is for cars to remain safe and roadworthy by not allowing monster wheels to be put on tiny cars, whose chassis/suspension etc wouldn't be able to handle it properly.

how similar is an r32 to an r35? chalk and cheese, but for the GTR label. i doubt very much you'd get away with it on that basis.

i go by the tyre placard, ie. 25mm wider than the widest rim on there.

your point about a r32 compared to a r35 is taken is but i think your failing to see the point here.

bigger wheels half the time are used to help handle better. its half the reason why you see monster GTRs with something like 18x11 wheels despite then having no where near that big from factory. wether your using drag applications or track, sometimes you jsut gotta go bigger.

i would like bigger wheels on my car and would like knowing its legal........thats all

Always thought it was,

Make: Nissan

Model: Skyline

Series: R32/33/34

In the VicRoads documents, I've always translated the 'widest for that vehicle series' as in the widest that series has got. For example the R32 GTSt's only got 15x6.5" wheels where as the GTR's got the 15x8". The 15x8 was the widest from that series (R32) so you could legally go up to 9" wide (both on the GTSt and GTR) and whatever diameter as long as it's 15mm within factory rolling diameter (total, both tyre and wheel).

No idea if that's correct or made sense, but I always thought it was like that. :laugh:

Umm there is one... :laugh:

Its called the EPA/RWC thread in this very section thats been there since Feb 2007.

As for the actual VicRoads VSI documents, there is no point uploading them.

You should always download from the website if wanting to view them incase there are ammendments and so on.

So uploading the to the forum itself would not be beneficial on the chance it proves old/outdated information

Don't quote me as I'm not certain, but back in my FordForums days, I remember everyone saying that they could run XX size and diameter wheels on their base model Falcons etc due to the XR's in that series having XX size wheels.

I think it goes off the largest available factory option for that series. So for example a BF Typhoon came with 18's, but optional 19's therefore you could get away with 21's if the rest of the dimensions were within the guidelines...

As far as translating that to Skylines, it's only really the 34 that has anything 2" bigger from GT-R to GT-T, with 33 GTR's only being 1" bigger than GTS-T's, but that'd still allow 33's to run 19's as long as the widths and tyre sizes were within the guidelines...

Think there's also another rule of any wheel/tire upgrade having to be within 15mm of the largest/smallest factory option wheel/tire package for that car...(included smallest as you can't run 13's on a car that should have 17's etc)

theoretically you were to go on the bases that 15mm was the largest/smallest size package, you could essentially have 25" wheels so long as the tyre is small enough to compensate for the 15mm no?

I think there's more than the 1 rule as far as wheels go...So you might be within the 15mm rule but outside the other ruling as far as wheel size goes...From memory its 2" up/down on the largest/smallest factory option

wat i would like to know is what vicroads clasify as series.

if indeed they look apon series like like dezz said. base model falcons being compared to high end XR6s, it should apply with skylines aswell.

the new R35 sports 20 x 9.5" (front) and 20 x 10.5" (rear) .

which would hopefully mean i can run my 19x11s on my car :laugh:

i think what dezz meant was that you could run the width out of your serries, so if you have an R33, you have to keep to the max width that was available, so that would mean R33 GTR size wheels, plus that 15mm rule

It's all in plain English..

Falcon, say a Ba...regardless of spec it's still a BA series falcon. So if the largest diameter rim is 19 x 35 x 235 from the factory you may go 15mm oversize in rolling diameter and up to 25mm in width.

Skyline, r3- series whatever....blah blah, same deal, regardless gtr,gtst,gts ect you can go 15mm taller in rolling diameter and 25mm wider over factory spec

Yep, thats what I meant. Not that you can go off what the R35 has....

So basically all GTS-T owners would go off GTR specs as they're going to allow you to run the largest wheels

As for fords, EF-EL would go off EF-EL XR's, AU off AU (series 1, 2 and 3) XR's and so on

yes wider wheels can give you more traction, but what ric is trying to say is that cars are designed with those wheels in mind... so certain suspension components are also engineered to work in with the standard wheels.. and a large change from standard specifications can have adverse affects, such as the wheel bearings.. if you go too wide with a very drastic offset, you'll start to load the wheel bearing beyong thier engineered tolerances! so the limitations imposed by vicroads and adr, are not there to stop you having fun with which wheels you want to put on your car, but as a safety guideline.

^^ or even snap wheel studs and so on if the car is too low and rims dont sit right etc.

There is a can of worms so to speak about all the possible dangers... ye you might not be bad yourself, but this is the majority of society and some of the stuff you see on the roads is a clear reason why these laws are there as they are just dangerous

    • Oh, that's grim. Something bad has been happening there.
    • Put an endoscope down the hole and saw this. Not quite all around the bore but a good 60% at least. Chin to the chest and towards further disappointments I guess.
    • 2 does "sort of" applies, maybe......but looking at what parts would be needed for the swap to get engineered, registered, and insured, and basically that's everything under the car, the modifications the make it legal would be problematic and horrendously expensive, all for a street car that just cruises around and hits a few twisty roads on the weekends Also, from looking at the NSW rules and Regs, with all modifications that is required just to make the car safe and not twist itself to pieces, and then actually get registered for street use, may still be impossible nowadays As for 1, when you add in a fresh engine, fresh transmission, rear cradle and diff, tailshaft, suspension, brakes, cooling, and all the other fabrication required, your probably looking at up to $100k to do it right, all for a 20 year old MX5 that is over engineered and you would never be able to actually use the power it has on the street, much like your beastie, which I love, but you actually track that thing and can use all of its powers in anger, in a safe environment  Hell, the old Bogan Cruise Ship had more power than I could use on the street, and in hindsight, I went a bit silly on that thing, it didn't really need the 500hp it had for what I actually used the car for, it was fun, but basically unusable on the street if you value your licence  As for cams, yeah, I'll probably book it in for them to get installed and tuned soonish, like next month after MX5 Mania are back at work....... and yes, I've already sent a email to bin the turbo quote and quote instead to install cams and a new Fluidampr balancer that will suit the 2.5 better than the OEM 2.0 balancer that is swapped over for the 2.5 install, as the balancer needs to get pulled to time the cams it's a while your in there sort of thing I did think a bit about flex fuel for a laugh, but being na, and no where really around locally anymore to get E85, I've binned that idea, so no sweet sweet corn smells are set for the car I wish E85 was more of a standard fuel, it's better for the environment, better for tuning, plus that sweet sweet smell we all love As for fitting in the family, that's not needed, as everyone in the family already owns a car that can seat 5 humans comfortably enough, the MX5 is "my toy" As for buying a car that is already built, nah, I would rather pick and choose my parts, I enjoy the process, and in the big picture, the additional cost is well worth the enjoyment, and the occasional frustration, I get out of doing it, albeit with other people spinning the spanners, and me, just paying the invoice 🤣
    • Excuse me, but 2) does apply 1) Would also apply if you consider how much is spent in the alternatives. Also there's the option of 3), buy one pre-built that you can put your family in (it's me, it's my car)   That said, I went on a ~500km drive the other day. I didn't use anything more adventurous than 3rd/4th gear at about ~3000RPM and 50% throttle and I was going as fast as anyone has any sense doing on a public road, with enough grip to the point where I didn't want to go any faster. I was obviously under the limit of the current car etc etc. MX5 with 2.5 N/A to achieve the same speed would be more fun for any road scenario. Maybe consider cams. I wouldn't boost it. The use case is just not there and it won't actually make the car more enjoyable unless you really do plan on wringing gears from 1st to 3rd (at least) at 100% WOT on a public road to 150+kmh.
    • Great if: 1. You had all of the money for everything else that is required  2. Lived in a country where you could actually do this and drive it legally on the road Sadly, neither applies to me As for the turbo, I am having second thoughts, mainly for engineering/registration legality reasons and insurance  Not saying I've finished doing stupid things that I probably should do to the MX5, but boost, and V8 engine swaps isn't on the cards Strange, but true
