Vehicle modifications
Owners sometimes modify their vehicles to give them a distinctive appearance, to improve their performance, to add desired features, change the engine (alternate or replacement engines), suspension, or to add a long-range fuel tank. Others modify their vehicles so that they are better suited to a specialised purpose.
Vehicle owners who wish to modify their vehicles need to follow the vehicle standards guidelines and relevant approved codes of practice that apply to the modification of vehicles.
Modification plans may need to be reviewed and approved before the modification is made. If this is needed, a fee may be payable.**
