Hi
How do people get 35's legal in vic, I know engineers have to do a swerve test and brake test, but where are these engineers and what does it cost??

I only have a 2" lift on my gu ute and will be, if i can get it done legally, put radius arm spacers in. As only want the extra clearance for my diffs?

any help much appreciated

finding the right engineer is the most important part of any modification.
pretty sure you should be able to get a list of approved engineers from your states department of transport (or whatever it's called in your state). Then just hit the phone, ring them all and ask them what'd be required for them to approve it, or if they would at all.

Asking on a forum will get a heap of different answers, you can only find the right answer using your phone.

You haven't been able to engineer a tyre size increase in Vic in a long time. If they were previously engineered before rule changes, you can keep it, but no new ones unless its an axle change to an axle that came with 35s or requires a 35 for 'correct geometry' . I was told that by a guy that worked at Marks when I queried a few years ago.

In the real world things work different from on paper
but good on you for defending your chosen brand (looking at yr signature it must be a landcrab)
He's right though. The numbers don't lie, on paper and real world.

There are a couple of well known weakest links that everyone knows about, and everyone here loves to talk about-front centres and studs in the rear hubs. Both can be worked around with strong aftermarket support, but that depends what the argument actually is about, stock or modded.

It's a shame GQ/GUs weren't sold in the US, there would probably be a lot more aftermarket support.

Congratulations of compiling a long list of largely irrelevant measurements. I've neither the time nor the interest to audit the accuracy other than to say engineering is more complex than wandering around the shed with a set of verniers for a few hours. Some actual load ratings for the affected components would have been more relevant.

As for the rest of the driveline..perhaps a real world poll of how many axles, cv, diffs and steering components people who actually use this stuff offroad have had to replace would be more helpful than your desk based propaganda.

Your suggesting the patrol diffs cannot safely support the load of a 35. That's bullshyt. That's fact.

Cant help you if your being ignorant of facts and you rely on anecdotal evidence. This thread is about ENGINEERING 35''s, what I have posted up is what the ENGINEER cares about to make the decision, not "my mate saw a patrol run 35''s so they must be ok to run on the road", since you dont understand engineering maybe best you stay out of this thread.


As for all the other stuff about failures etc, sure things fail, just as much patrol stuff fails as landcruisers big whoop, every story you post up of a cruiser thing failing there is a story for patrol stuff failing, ie, popping CV's like cheese sticks in the snow, rear axles constantly twising or chassis cracking, rear springs mounts ripping out etc etc

I dont evan like going wheeling with cruisers anymore cause there such pieces of junk! Dont stop breaking. Took 10hours to get this thing through a 3 hour track, first snapped a cv( couldnt believe how easy) then power steering shat itself, it the. Dropped its engine oil and blew up! Never againnn.

Yes they are a liability offroad. Toyota haven't made a decent driveline since the 40 series.

Don't forget the tissue paper bodies and chassis either. Open the doors or tailgate when it's flexed up and the body twists so much they don't shut again.

Landcruisers are the Claytons 4wd..."the 4wd you have when you're not really having a 4wd"

On a different notes that track looks like fun.

You can't be talking about 100 series vs GU then. A 100 series body is better built than a GU. Less flex, fewer rattles and squeaks, tighter panel tolerances, interior fitment is streets ahead, doors close nicer.
The GU body isn't badly made, the 100 body is just made better.

80 series body vs GQ body... there's no comparison there. The GQ body is just an MQ body with some flares tacked onto the side. A fine body by early 80's standards, but not 90's.

60 series body vs MQ body... The MQ body miggght be better, but I don't have enough experience with 60 bodies to say for sure

ROTFLMAO... Toyota lying to their fanboys for the last 25 years with that "unbreakable" advertising. Maybe the ACCC should pursue deceptive and misleading conduct charges. In Toyotas defence they are probably just as surprised as we are that there are actually people out there stupid enough to believe it and hand over their cash.

The old you can't engineer 35s in Vic again:bananaro:

You can, and people WILL still get them engineered:bananaro:

You can reg just about ANY thing IF you have the money\time\patience;)

Walk into an engineer with a half baked GQ, with its Ebay special lift, knock off spotties and a leaking rear main, he will tell you were to go:p

Go back to the same engineer with the idea and ASK FIRST what needs to be done to make it happen, act like a normal human and not like a ******, and as long as they know you are serious you will get it through, wont be cheap, but I can happen:bananaro:

I was looking at getting 40s engineered not that long ago;)

It is about liability and the engineer has to be able to account why he did this if it all turns pear shaped.

Put a built set of D60s under a Patrol and you can pretty much do what you want, if people sat down and added up the costs, the D60s are awfully tempting, and no you would not spend the money for an every day, but a decent build you would:cool:

So many options to BDR, rockjocks, curries, dynatracks ...... yanks have all the cool ****, but they do ship to Aus !! lol

Plenty of 60's and 70's sitting around farms and junk yards to build too, hell I had a shot at a 14 bolt rear and high pinion 60 front once .... kicking myself I didn't grab them and chuck them in the shed for a very rainy day.


Unfortunately along with re-engineering your driveline you would then have to do suspension and chassis work etc etc etc ..... but thats the type of bullet proof stuff engineers like to see and would near on 100% ensure that the vehicle gets the tick of approval.

On patrol diffs / running gear ? - eh, im sure it could be done for 35's but as people have said, money, engineer, money so on and so forth

HeyHey, if you notice I never mentioned Patrol diffs;)

There are a LOT of Patrols running standard GQ diffs that are engineered on 35s:cool: , mind you they got done a while ago.

Last I spoke to an engineer, it could *almost* be possible to do it, if you ran an RB30, he said it comes down to wheel bearings and the load they see apparently.

Don't make a mountain out of a mole hill, why in gods name would you need to do destructive testing on a set of diffs to find out if they can handle a 35:rolleyes: , you only need to find something that either weighs a LOT more than a Patrol or has a bigger tyre, just about any fullsize American jigger would do, but it is not the cheapest option that's for sure:crazy:

Or build something pre ADRs;)

there you go nino, you can run 34's on yr gu ute if tyre placard has an option of 7.50 x 16's(split rims)
if the tyre is approved for road use a simex 34 radial or something else around 290/85/16.some tyres are marked as the casing size which gives you a slightly bigger tyre overall

vvv see below post, if it's a dx gu ute
