Vehicle Modifications & Modification Plate Certification in Tasmania

If you’ve modified your vehicle beyond standard factory regulations, it may legally require a modification plate (mod plate) to certify that the changes meet Australian vehicle safety and compliance standards. At Cooper Automotive Tasmania, our experienced team can complete approved vehicle modifications and arrange certification check-off, helping ensure your vehicle remains safe, roadworthy and compliant with Tasmanian requirements.

Whether you’re upgrading performance, changing vehicle configuration, preparing a campervan, or modifying a vehicle for accessibility, we can assist with both the mechanical work and the compliance pathway.

We provide modification support and certification check-off for a wide range of vehicle upgrades, including:

  • Engine upgrades
  • Seating additions or removals
  • Child restraint anchor point installations
  • Gearbox transplants
  • Rear differential swaps
  • Wheelchair-accessible vehicle equipment fitments
  • Campervan conversions
  • Upgraded brake systems
  • Long-range fuel tank installations (T4 certification required)
  • GVM upgrades (T4 certification required)
  • Vehicle weight verification through weigh-forward assessment

Our experienced team understands the engineering approval and compliance requirements specific to Tasmania, so you can move forward with confidence knowing your modifications are completed correctly and documented properly. 

If you’re planning a modification — or already have one completed — talk with Cooper Automotive about getting the right certification and check-off process underway.
