Well I found this on transport SA's Web Site..
Raising
Vehicle ride height can be increased by any combination of the following three methods. However, it
is important to note that a total lift of more than 50mm requires prior approval and a report from
a CPE.
Tyres / Rims
The fitting of rims with a different diameter to those listed on the vehicle’s tyre placard is
acceptable, provided that the overall diameter of the alternative rim/tyre combination is not
greater than
15mm over the largest combination or 15mm smaller than the smallest combination specified on the
vehicle’s tyre placard.
If you intend to fit rim/tyre combination outside the 15mm limit, then an application must be made
to Vehicle Standards for an Exemption from that particular section of the Road Traffic Act and a
report from a CPE supplied with the application.
Any replacement tyre fitted to your vehicle must also have a load capacity equal or greater than
the minimum specified on the manufacture’s tyre placard.
Suspension
When raising the ride height of your vehicle by changes to the suspension, you must ensure that the
original amount of rebound travel is maintained. The rebound shall be limited by the same method as
the original manufacturer (i.e. limit straps or shock absorber full extension).
The vehicle ride height cannot be raised by:
- Extended or adjustable shackle plates on leaf springs.
- Relocating a leaf spring on the opposite side of an axle to that of
the vehicle manufacturer.
- Spacer blocks mounted above or below the coil spring.
- Wedges or blocks located between the coils.
- Spacer blocks mounted between the top of the suspension strut
and vehicle body.
Body Lift
The body of a vehicle can be raised by up to 50mm by the fitting of spacer blocks between the
vehicle chassis and body at their mounting points. The blocks must be manufactured from steel,
aluminum, or metal of equivalent strength. In some cases the steering shaft may have to be extended
as well as longer brake hoses fitted.
If there is any alteration or replacement of the original steering components, then the
modification requires prior approval from Vehicle Standards and a roadworthiness inspection upon
completion. A report from a CPE may be required.
completion. A report from a CPE may be required.
General Requirements
When the ride height of a vehicle is raised, the vehicle must still comply with all legal
requirements, including:
- Lighting – the raising of the vehicle will affect the height of the vehicle’s lights
and reflectors and these have to remain within specific boundaries. Care must be taken to ensure
that the raising of the vehicle results in the vehicle not complying with the legal requirements.
- Mudguards – There is a minimum height that the
front and rear mudguards, or mudguards with mud flaps, can
be above the road surface. For a vehicle with off-road capabilities, the distance from the
mudguard/mud flap to the ground cannot be greater than 300mm and 230mm for other light road
vehicles.
- If the vehicle’s ride height is raised when a tow bar
is fitted, the height of the tow ball should be corrected to
maintain its original height prior to the vehicle being raised.
If you intend to raise the vehicle by over 50mm by either one or more of the three methods
mentioned, then an application must be made to Vehicle Standards prior to the commencement of the
modifications. A Statement of Requirements will then be issued identifying the vehicle, the
intended modification and any applicable requirements, including a requirement for a report from a
CPE. On completion of the work and certification by the CPE, the vehicle would be required
to pass a roadworthiness inspection. A fee is payable for the inspection.
The CPE would have to address the modifications, the stability, handling, braking ability and
verify the modified vehicle can safely
be driven on public roads.

So technically a GU spring would be illegal in South Australiadoes it mean I will abide by the rules... of course I will I am a responsible person..
COUGH COUGH COUGH



does it mean I will abide by the rules... of course I will I am a responsible person..
