Here is more details on the actual modification rules and regulations:

I had a quick read through that link and it isnt very specific in relation to lift apart from where it touches on the bump stop distances, have I missed something
Tyres were a bit vague as well I thought, apart from referring to the tyre fitment industry

I agree Kyle... it's a bit vague... seems more biased towards lowering a car rather then 4WD's and lifting them.

Seems to be something missing, more emphasis put on window tinting

That document is very outdated (2008) and will be replaced with the new document in coming months. The closest actual document that has been released is this one-

There are some big changes to it though. You just have be patient and wait for everything to be updated.

There was some big suggestions being put forward before the Qld parliament, is there any indication that some of those may have been approved?
Im still a little confused as it is meant to be National yet states seem to be going it on their own.
Please Explain

just found some lunch time reading and looking into

This'll make it so much better (hopefully)

Some light reading for the QLD boys... 200+ pages

Double post.

i heard that we are aloud 50mm increase in tyre diameter, can anyone confirm this? And if so does that make a 265 75 16 tyre now legal on an sr?

Under the new Code of practice you are allowed a 50mm tyre diameter increase.

SR came with 205/70r16 = 693mm O.D.
SR5 came with 255/70R15 = 738mm O.D
265/75R16 = 804mm O.D.

I'll leave the rest of the maths to you.

So SRs can legally run 29", and SR5s can legally run 31" ?

Seems a bit stupid that the SR5s are allowed an extra 2" tyre because they came with floor carpets and some shiny bits.

I've just had a bit of a read of the legislation, and the 50mm diameter rule is in relation to the vehicle MODEL not the luxury level, and it's the maximum specified.

In this regards you might be able to get away with fitting a tyre placard from the Hilux that came with the largest stock tyres and go 2" from there.

Mine came with 265/65/17 or 776.3mm

Depends on the year model. The newer model also has upgraded brakes to allow larger wheels like the TRD.

NCOP VSB14 link here: http://www.infrastructure.gov.au/roads/ ... _ncop.aspx

Click on •NCOP11 Section LS Suspension and Steering V2 01Jan2011

Total lift of 50mm which includes all tyres,suspension and body lifts together.
Requirement of certificate for 50-150mm lift. Over 150mm lift seems to be illegal.
VIC and QLD have adopted the new regs as stated on Cooper Tyres and Mickey Thompson Tyres websites, Though each of the states has changed the maximum of 50mm to 75mm (which helps a bit).
Getting a certificate will become much harder and more expensive.

This is really going to hurt the 4wd enthusiasts and industry as a whole.

the max lift without cert is 75mm, including all tyres, suspension and body lifts. From memory all body lifts need to be certified regardless. in qld anyway, nothing like a national code of practice to be broken down to not be national.

How many cars can be lifted 150mm and still have the headlight under 1200mm. Whatever NCOP states, your car still must comply with all relevant ADRs for when the vehicle was produced. Remember that 150mm is 6 inches which is a fair amount.

Bear in mind that NCOP allows the tyre diameter to be increased 50mm without engineering for 4wds as opposed to the 15mm that used to be allowed. Can't have everything and it if you look at the number of people that will benefit from NCOP due to allowing larger tyres, etc as opposed to the number of people that want/have over 6 inches of lift (if you already have it, it would already be engineered so new rules are irrelevant) I think it is an improvement overall.

Yes it allows a 50mm tyre increase but then you cant have a suspension lift because the total amount allowed overall is 50mm. QLD & VIC 75mm, not sure about other states.
That is not an improvement its more restrictive.
