NCOP for QLD finally!

[DaveZ Member Find all posts View Profile Close DaveZ]

Well no tyre store can give me any help yet, they say come back tomorrow and see if the NCOP has been adopted and just what it contains. Our local guy insists it will only be 25mm increase in diameter but the NCOP document clearly states that 4WD vehicles will be allowed 50mm. There is apparently going to be a QCOP document as well as not all our rules are going to align with the NCOP. Gee they like making things difficult don't they.

Here is the link to the Qld doc

So it looks as though amts is correct. 50mm of lift inclusive of tyres and suspension so if you run 70 profile tyres on a 17" rim that steals about 15mm of lift.

50 < LIFT < 75 has this little problem:

Designs that are not covered under Code LS9 are listed below:
• Design for vehicles originally equipped with ESC that have not been approved by the
vehicle manufacturer or proven through testing;

The following is a summary of the modifications that may not be performed under Code
LS10:
• Modifications to vehicles originally equipped with ESC that have not been approved
by the vehicle manufacturer or proven through testing;

I am not sure what the testing regime is because there is talk in there of a lane change test (Has the vehicle undergone a Lane Change Test as per Code LT2in the NCOP?) and the acceptance criterion (Was the driver satisfied that the vehicle was safe to drive?) Is that it?

What's going on with long range tanks? Does anybody know?
The Roo.

Don't believe there is any change here, they still need to be compliance plated if installed, changed or removed

50 < LIFT < 75 has this little problem:

Vehicle lifts that do not exceed 75mm, and are achieved by modification of the suspension and
fitting of alternate tyres and rims only (do not include a body lift) do not require certification under
the LS9 code. Any person performing this type of modification must ensure the modified vehicle
meets all the technical requirements of the LS9 and LS10 sections of this code, however no formal
certification or lane change test is required.

50mm lift + 70 series tyres should still be pretty easy to get done by the looks, assuming that a +33mm increase in tyre size or increased suspension height isn't considered to affect the stability control, be interesting to see what they say about that. Thanks for all the info guys. Back to the tyre store again tomorrow or Friday to see if this has actually been implemented.

Cheers,
Dave.

IF you don't have stability control...

IF you don't have stability control...

Not quite. If they deem the modification to affect the stability control. Not sure where the guidelines for that are written though. More than likely the spring lift will be considered to affect it, not sure about the slight increase in tyre diameter though.

From what I understand a "lane change" test is to be conducted on any mod above 50mm. What and how that is done I'm not sure. But applies to any vehicle, stability control or not.

Cheers,
Dusty

Double post, sorry

If you read a bit further it says that up to 75mm has to meet the standards for >50mm lift but no formal testing is required. Would still like to see their interpretation of what mods affect esc.

Dusty,

The lane cgange test is derived from an international standard (ISO 3888-1). Unfortunately it seems you have to pay to access this publication. Have a look at page 10 of this site which offers a summary.

Hope that helps.

Thanks Mike, good info there. I can't imagine these tests, when required, will be cheap. Obviously staying under 75mm might be the logical target. For the 150 that would see the usual 2" lift and a change to 70 profile tyres allowed without too much fuss. I don't for a minute disagree with the need for regulation, no-one wants a 3 ton fourby coming round the corner in the wrong lane just because it's lifted to high and has excessive body roll. And I suppose that's the heart of the matter, finding the compromise of on road handling and off road capability, all the time keeping everyone safe.

Cheers,
Dusty

So, is ESC on the GXL?
And,
Is KDSS classed as a type of ESC ? ( I assume it is)

Cheers,

Jeff

This is how I read the new NCOP for QLD ~
Up to 50mm suspension lift and an increase of tyre diameter of up to 50mm therefore a total lift of up to 75mm (50mm suspension + 25mm tyre radius) is accepted without certification.
If a vehicle is fitted with ESC and the lift does not compromise the function ability of the ESC, then this is also accepted without certification.

Please feel free to correct me if I'm mistaken.

Cheers,

Jeff

I tend to agree, from what I can work out. So like I said you should now have no problems with 70 profile tyres and "X" brand 2" suspension. Happy days.
