    I'm gunna disagree with you there. Having recently looked into this myself I found the current rules from the dept of transport website, then spoke to a QLD based engineer.

    50mm larger is all you can go on diameter of tyres, and 50mm is all you can lift in springs, neither of which require an engineer certificate.

    You can do a further 50mm body lift however this will require an engineer certificate. It is however pretty pointless, as you can already fit the legal limit of tyre size without a body lift.

    not sure what got lost in translation but

    a, read the original statement again and b, Find a better engineer...

    theres more involved in it than just bolting on bigger tyres, the lift kit and the body blocks. but its doable and if the engineer approves it, documents it and plates it then its also on road legal.

    50+50+50 for a total of 150mm over stock height is the MAXIMUM you can do without requiring engineering certification. (and the body block lifts may now also be questionable)

    For a disco generally going a 2 inch lift and an extra inch of rubber (which only gives a half inch rolling radius increase) is as far as you go without having to start looking at brake lines, camel cuts, castor bushes, brake upgrades, drive line components. its also easier to get an early disco approved for a body lift than a later one.

    First up, don't patronise me.

    If you read section LS9 part 1 in the link below you will see there is no allowance for increase of ride height beyond 125mm.

    It clearly states that 75mm in a combination of tyres and spring lift is the maximum allowable permitted without certification.

    http://www.tmr.qld.gov.au/~/media/Sa...s1112part1.pdf

    Please note of course that this is applicable to QLD only.

    If you can provide documentation to back your claim of 50+50+50 I would be more than happy to hear it!

    which nicely summates what I said the limits of what you can do without an engineer..

    Since I cant patronise you, I'll challange you.

    start there and begin digging here's a hint, the D1 in question does not have ABS brakes nor Airbags

    welcome to the squirrelly world that is ADRs, VSB, AS and NCOP, be careful of contradictions between the documents and applicable vehicle dats and versions.

    Have fun.
