Modification Plates
Owners sometimes modify their vehicles to give them a distinctive appearance, improve their performance, add desired features, change the engine (alternate or replacement engines), suspension, adding a long-range fuel tank.
Others modify their vehicles to be 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.
Many intricacies are required to certify any modifications and some regions cannot offer some codes. We suggest you contact us first to ensure the requirements are met.
Please Note: LS11 GVM and LS12 Caravan ATM upgrades are only offered by our Maryborough workshop.
Please Note: We do not do lift modifications
