Lowering a vehicle in NSW - recent changes?

[Rocket36]

Wasn't it possible to fit coilovers or say Eibach springs previously without an engineers certificate? I thought you could as long as the vehicle retained 100mm minimum ground clearance.

The way I'm interpreting it you now MUST get an engineer certificate if you deviate lower than stock height at all.

Or was that always the rule as Rocket36 points out?

Since it was a minor modification it never needed to be engineered so long as the vehicle itself was still within the ADR standards. While you could get a defect notice to prove it was legal, your normal run of the mill Blue Slip place could say the ride height was appropriate.

Now ANY change needs an engineers report, although only if it's made after 12/07/2009 (or you get defected or need a blue slip).

So quick, get your coils in before the 31st



...Now we need people to go out and hunt up some friendly engineers who want to provide said certification for suspension on our dubs and post up a sticky with locations and prices (where available).

This has a fair bit of grey area I think. Individual components also have their own ADR which a lot of the after market stuff doesn't not have as it costs companies a lot to get ADR approval for products, which in turn would push up retail costs and they'd lose customers. That doesn't mean their products don't - most of them are a lot better than stock components. So while the ride hide is legal, the individual components technically might not be. Doesn't mean you'd fail an inspection or be un-roadworthy, it just technically means the modification would still be illegal.

That's my interpretation though and I'm not sure it's 100% accurate and why I think there's a whole lot of grey area. Correct me if I'm wrong, but unless a car is stock (everything stock meets ADR standards approval or it can't be sold) or the modified components meet ADR standards, then it requires an engineers certification to be legal.

They have so many conflicting and poorly thought out regulations:

The RTA has a database of standard vehicle suspension/wheel specs for different models and their acceptable limits, so I looked up my Golf:

I looked up the specs for a 2004 Golf and it says hub centre to wheel arch stock measurement is 370mm at the front with a RTA specified minimum acceptable measurement of 353mm. The GTI came 15mm lower already, so that's 355mm ( ie, 15mm down from 370mm). So they are saying the car can settle 2mm and then it's illegal.
