Outer Limits 4x4 Board

ok here i am trying to get a road worthy for my nissan patrol gq in qld coils are lifted no body lift ok. the qld design rule states the car cannot be lifted by more than 1/3rd of the original distance bettween the rubber bump stops and where they touch on the diff sounds fine but where the hell do i find this spec so i know and can prove this spec to my mechanic. so far qld trans cnt help mech no help cops no idea(duno how they can defect any1) nissan no good qld transport vechile standards devision no idea plz help me

maybe find a standard GQ and measure the distances. How tall are your springs?

kinda similar question.

Do you need a mod plate for moving bumpstops?


im sure google will answer teh 'ginal question

i cant find it on goggle bt i need it to be officel anyways so i can prove it. duno bout bump stops. 4 inch coils in it with all rods bars castor bushes ect superiour adjustable so its done rite i wnat to get it cleard nd done because ive got a bunch of parts to make her comp ready sittn in the shed bt cnt bolt it on till i pass. starting to think of chucking standard coils in it nd trying to find sum1 to lend me sum smaller tyres.

This document mentions some legislation and states the clause you are talking about, it's from 2003 though?

Here's another guide that mentions it as well.

Do not alter the ride height of the vehicle by more than one-third of
suspension travel specified by the vehicle manufacturer

this quote from DOT above

If you look at it this way the front shocks are approx 200mm travel okay less 1/3 = approx 60mm lift
rear 255mm approx less 1/3 = 75mm lift

Thats my thinking its all a grey area.

I think you should ask your mechanic to show you where it is documented from nissan about ride height and suspension travel as i am pretty sure no one will be able to including transport dept and if they can't how can you.

thankyou for the info mate yea i found the 1/3rd rule bt the only mechanic in my area who can do rwc pretty much dosnt want to deal with it yea its def grey considering nissan themselfs cant tell me the factory spec due to the age of the car. i tell you if i ever get defected for height ill be takn them to court because no1 can get there hands on the info. my car has superior 4inch coil lift no body and all superior adjustable links. do u think this is not legal height? when he looked at it he said it all looks well done but too heigh should i just take the trip to mackay and try a 4x4 mechanic there.

4" would be about 100mm lift.... that lift plus the tyres i assume you're running to fill that void are almost certainly going to be "illegal" without an engineers cert.

that said - if no one can prove the stock bumpstop distance then 1/3 can be whatever you say it is...

Would one of the spring manufacturers have an idea? They're the ones saying their springs are ?" higher. Higher than what. They might have some number to base their spring heights off. Hope that made sense.

good luck with this one!
There is no ADR for determining std vehicle height, and as yet you will not find 1 person in DOT that will sign off on a specific height measurement (please tell me if you do cus' then they are liable - as presidence will be set and this is then court admissable). It is really a lot of hearsay. You can theoritically drive in to DOT with a 6" lift and get them to approve it, BECAUSE - they do not have (nationally approved and certified ) dimensions of every vehicle. So just tell them to prove you wrong or sign the paper telling you that it is not the height you say it is and they must attach evidence.... Then ask them for the ADR code on how to measure vehicle height? (hey they have a specific way in which they must check everything else on your vehicle!).

I had the same issue with my 4 Runner.

I found a genuine Toyota "body and chassis repair manual" on the web which has detailed suspension height and chassis component details.

Perhaps Nissan made one too.

Cheers

mate id just put in some standard coils get it passed then put back ya 4inch, if everything is adjustable


i think i still got my standard coils laying around if ya want them pm me let me know

Measure standard with empty tanks and lifted with full tanks

does a patrol have 12 inches of compression travel in stock form? no.

Put some stock springs and tyres on and get your roady. Good luck finding a qld mechanic who would put there name down on a rwc for a 4 inch lifted patrol on 35s.

next prob is no adjustable rods legal in QLD no 35s on patrols , good luck with that .

Wouldn't it be best to start here and then work out where to go after reading.

mmm, While I'd like to agree there's plently of 4WD's in QLD running around with 35s and 6+ inch lifts in front of cops.

Hell there's a hilux just up from where I work with 35s and the bottom of the body is still above the height of the tyres.

Then while I nearly got defected for having different treads (only got fined) some patrol, rolls on by with 35 muddies and a 4-6" lift and that's what the cop was whinging on about to me, about 1 min before that guy rolls by in front of the cop while the cop is writing up my ticket.

So while the law, says X you need to be caught and fined, before it really means anything, eng certs only help you to get out of fines but if you never get fined well whats the point of the eng cert?

dosnt matter what size tyre you have it still wont make the bumpstop height any diff
