here is the reply to the above asked question by dan:

The suspension requirements fall into a few special requirements;

Suspension travel.
Minimum bump stop clearance.
Ground Clearance.
Structure sound, fitment.

I guess the usual ones are like the ones you have asked.
Can I fit lowered springs ?, yes however they cannot be cut or heat affected, must be retained in the system when load is removed (can't fall out if jacked up) include structurally sound, Must retain 2/3 of manufactures bump stop clearance and can't be below the manufactures min ride height, can't be found below the 100mm ground clearance. Hopefully this is not too technical but all these things affects you vehicles handling.

Basically, if you fit one of the more common suspension replacement options available for your vehicle that is recommended by a retailer you should not have a problem, and no additional engineering reports should be required (except Coil Over as discussed). You can discuss with the retailer or ring our Vehicle Inspection Technical Standards (VITU) on 62077236 when you decide on the product or range. Please remember that the springs are only one component and may need to consider the whole suspension.

Ie: Pedders, Lovells, Koni, King Springs Whiteline etc etc. I have include some hyperlinks to some of the manufactures Q&A webpages that may help you.
