GVM/GCM Upgrades can be marketed in completely different forms from one manufacturer to the other, and it becomes easy to get confused by all the figures that can be thrown around. Misinformed customers and social media platforms and forums are the most common reasons as to why people are informed of incorrect information.
The term post rego is used when a vehicle has already been registered in Australia.
The term pre rego is used when a vehicle has never been registered.
Nationally recognised is used on any upgrade that is completed post rego, and certified in the relative state the vehicle is registered in. These upgrades are recognised across Australia, if it has been certified and complies in the relative state the vehicle is registered in, that upgrade is legal across all Australian states and territories even though it may not comply with their current legislation.
Note: Transferring rego across to another Australian state or territory may require an additional engineering certificate and compliance from a relative signatory for the required state.
Federally approved is completed prior to the vehicle being registered before by a certified Second Stage Manufacture (SSM) with the required government documentation and testing required to upgrade these vehicles prior to registration. Meaning these upgrades can be registered and transferred in any state without any issues and no addition engineering required.
GVM Upgrades Post Rego?
GVM upgrades can be completed post rego providing that the required testing and documentation has been completed, along with the required compliance with the relative state or territories legislation using the required signatory.
Note: There is small flexibility in regards to components in this scenario.
GVM Upgrades Pre Rego?
GVM upgrades can be completed pre rego providing the required testing, documentation and government approval has been completed.

Gross Vehicle Mass (GVM)
The GVM is the maximum weight that a vehicle can carry, including it's own weight. This is the maximum or total weight of a vehicle including body, payload, fuel and driver. It is a figure set by the manufacturer and is lodged with registration authorities and governs all applications and is stamped on the compliance plate of the vehicle (also referred to as GVW or Gross Vehicle Weight).
Gross Combination Mass (GCM)
The GCM is given for the total weight that a vehicle can carry and tow. This is the maximum weight of a loaded vehicle and trailers (also referred to as GCW Gross Combination Weight).
This is the same as Tare Mass, but with a full tank of fuel and without any accessories fitted, bull bars, tow bars, roof racks etc..
The maximum load your vehicle can carry as specified by the manufacturer. Gross Vehicle Mass (GVM) subtract the vehicle's Kerb Mass
(Payload includes all passengers and luggage)
The maximum load that your vehicle's front or rear axle can carry as specified by the manufacturer, SSM or relative engineer.
