Engeering Cert for Patrol on 37's

[Otto286]

Anyone know if it's possible to get an engineering cert for a GU Patrol on 37's in NSW and how much (roughly) it would cost?

[daz4b]

no 33s are the biggest allowed

[BlueSuzy]

no 33s are the biggest allowed

No. Depending on engineer. And if they want to work with vsi50 yet.

Ring around. Plenty in nsw/syd.

[joeblow]

....................good luck.

My mate got 35's engineered on his patrol last week in sydney, the engineer told him that he would do up to 37s no worrys. il ask him what engineer it was.

[brooksy]

Just because it is engineered doesn't mean it will be legal. Like to see a brake & swerve test !!!

35's are engineerable on a GU in NSW. You might get someone to pass 37's but most would say no

[daz4b]

tell me how 35s are engineerable when you can only go 2" above standard ,no engineers up here will do them daz

Don't GU's come with a factory tyre just under 33"?

both my GUs are engineered on 35's with 4/5inch lifts! both done by a very good engineer. NOT dodgy in any way!! last one was done 18months ago though.

[Slunnie]

There is nothing that is currently in the NSW regulations to stop and engineer approving 37's. There are some insurance constraints on some engineers that will prevent them from approving 37's.

2" over standard is an NCOP standard which has not been ratified in NSW and an insurance constraint for some engineers.

I agree. I'm currently in the process of engineering my GU on 35s with 5" lift and as long as the headlights are within the hight limit and all is safe (swaybars etc.) there is no problem.
Mine is also being engineered by a legit and well known engineer.

Some engineers won't look at cars that have already been modified without their consultation and maybe that's why they just say "nothing over 33s" ??
Easier to get rid of people than telling them they should've seen them (and paid) before they have done the mods.

AND they have to pass brake tests as well as swerve tests.
Good luck

My shorty is engineered for 35's and a 4inch lift plus 2inch body lift. Its also engineered for aftermarket seats, the rear drive shaft (double cardin) and the front GU diff with GU brakes. The cert is one of the reasons I bought this one and payed a bit more for it and was done in Newcastle. I'll have a look at the name of the engineer when I get back home on the 12th or so.

[adam big lad]

Good luck with the serve test i wouldn't do it in some standard 4x4!!!!

[tommy182]

getn mine engineered soon, said hes fine with 4inch lift, but said has to be standard tires. i thort that was not to bad, seeing as i wont be runnin the 35 all the time, just when playing on wkends

[AUSDOG]

37s are fine as long as the rest of the truck is up to scratch.
I got mine done a couple of months ago no probs. It's definatly
worth speaking to the engineer before the build if possible.
Otto, Pm me if ya want and I'll Point ya in the right direction.
He will not pass dodgy shit. So don't bother if it's not well built.
Worst case, he'll look at it and tell you what you need to change
to pass. The main prob I initially had was my 37s were on ten inch
rims. Took it back on 8 inch rims, all good. Mud flaps, and headlight
height were other minor things I had to address.

My brother drives a GQ trayback with 3" lift and 37" tyres - all engineered.
And it is amazing how good that thing drives on road.
No shakes, no vibrations and the breaks are good too.

But the hole car looks like new - so the engineer was happy anyway.

athol done my mates 37s on hes 4runner

werent you the one who said gu diffs under a navara was unengineerable on 4wdaction?

Athol now will only do 2" bigger than whats standard for an axle and a max of 4" combined lift. This is due to his insurance.

[Dirty]

You cannot increase the track more than 1.5", and you cannot go 2" larger than standard tyres.

Therefore if I got a set of Dana-60 axles shortened to be around standard GU width, do 37" become an option as the D60's have 35" standard (OKA at least, what about the F-trucks)??

You track and size comments are not accurate for those in NSW.

Personally, I would leave the axle wide and run with the additional track. The track increase measurements are for the given axle rather than the vehicle

Humm,

In Vic I thought it was vehicle based, hope I am wrong and your statement stands for this state also......

..... off to check....

- David.

[joeblow]

you can increase track more than 50mm only if you use a diff wide enough. you are not allowed to go more than 50mm on just rims alone.

[Charlie]

The suzuki section used to have a link to a video of the actual test, pretty easy actually as your not braking as you server, brake and swerve simultaneously a different story, a think it was Top Gear or some other pommy show that rolled a stock Rangie this way. Personally I've driven heavy vehicle that were alot more potentially dangerous once loaded than any lifted 4WD

Don't know about this, the track width limits as far as I am aware is based on chassis just like rego, ADR's regarding safety standards ,etc.
You can not just throw on a set of full width D60's on a Suzuki Sierra & say "but that is the factory width of the axles !!!"

It in the guidelines

Pg 2 under wheels - there are a lot of thoughts that go around on the internet, but they have to be checked in the guidelines.

http://www.rta.nsw.gov.au/registration/ ... 9_rev4.pdf" onclick="window.open(this.href);return false;

An important requirement for all replacement wheels is that the wheel track must not be increased by more than
25mm beyond the maximum specified by the vehicle manufacturer for that vehicle. Where non original axle or suspension components are fitted, the offset of the wheel in relation to the axle or stub
axle assembly used shall not be increased by more than 12.5mm each side of the vehicle based on the specifications
of the axle components used. If an axle assembly is shortened then the track width limit is taken as the axle
manufacturers original track dimension, less the amount the assembly has been narrowed, plus 25mm.
