Vehicle Engineers reports, 4WD Modification rules, whats allowed, what not...

Good luck with opening up this can of worms guys,

Not sure in other States but in NSW all mods have to be certified by a licensed certifier no longer an engineer.

And the reason they charge so much is probably 2 do with this

"As a certifier, you need to hold $20 million public liability insurance and $5 million professional indemnity insurance"

And the fact there is no set charge, its just negotiated between certifiers and their customers.

Wouldn't think the 20mil public liability insurance would be the deal breaker. I have it on my other business and its only $2500 p/a for it. I think it just more of a case of its a specialised thing so we charge a specialised price. Lol

Edit : What ET said.
I could cut and paste the links into state by state in the OP. I think will help scanning through threads???

From what I can gather, you cannot engineer 35s on Nissan axles.

From my limited understanding from the jibberish in some of these links. The ruling on 35's isn't governed on vehicle vendor. Its more so just on the size of the tyre. I found no words, so far, mentioning Nissan Patrol.
