The GVM upgrade process includes the following:

Finite Element Analysis of key vehicle components - Thorough Vehicle Brake and ESC Testing - Individual Vehicle Compliance Checks

Depending on your vehicle make, model and variant type, we may need it for several days to complete the suite of inspections and tests required.

All modified vehicles are provided with mod decal to be applied adjacent to the compliance plate of the vehicle.


ATM Upgrades - starting from $2,990

Do you have a caravan or camper trailer that's a overweight - or do you just want a little more breathing room when you travel. Many vans are able to carry more weight with limited physical changes needed. Send in your caravan details for immediate feedback, or book in for an assessment for a full inspection.

Truck Topper Installation

BTC & GCM Upgrades - from $1,990

Currently, SA permits upgrades to BTC (but does not recognise GCM), and currently WA permits GCM increases (but not BTC). NT does not permit either for light vehicles. Please contact us with any enquiries.
