QLD now adhering to the national standards

If my memory serves correctly that all rolled in half way thru last year.

If you read the detail, anything over 2 inches suspension lift, is more or less off the table for most due to the cost and the requirement for lane change testing.

Under the old regs you could get arround 3 inches suspension lift out of an 80 series...with no engineering and no please or may I...because it was bassed on persentage of factory suspenion travel.

Last time I was involved in a discussion there was no facility offering lane change testing in QLD....so that meant trucking the modified vehicle to NSW and back....because until it has been acredited it is illegal to drive on the road.

Even if you do have the money....remember the total engineerable lift is subject to a range of engineering conditions....which may make the full suposedly available lift a non starter for many vehicles....your 80 series may still be limited to 3 inches.

A down side is that a body lift that prior was dooable on a simple over pits inspection, now requires engineering...and from memory lane change testing.

BTW..the figures are in millimeters and not inches.......that can make a difference particularly in tyres.


On hiluxes and other light utes, the 50mm increase in tyre size might not be achievable because of the tyre sizes available.....mostly they will be well short of the 50mm or bust out and be over.

BTW you do know that 31 inch tyres are not 31 inches tall.....pretty well without exception the flotation tyres are all half an inch shorter than stamped with any road going tread pattern


Before you get exited read all the detail and do ya calculations in mm.

cheers

You would need to contact your insurance company if you fit tyres outside the sizes on the vehicles tyre placard!

After having a read of page 28, clause 4.11, I don't think you can go more then 50mm in total height change without needing a certification.

I just love this idea of "National Standards". Then of course, each state has to have it's little variations, lord knows why. We have things like a National Building Code, but each state has it's own little additions/subtractions.

Wouldn't it be nice if we only had one set of laws and standards in the old Aus! We have about as many people in this country as a large City, yet we still have 3 tiers of Government and all the hangers on that that brings with it!

I'd hate to be a national company trying do deal with all the state and territory administrations.
