Do I need a mod plate for every vehicle modification?

Not every modification requires a mod plate, but most changes that affect safety, emissions, or structural integrity will. Use the checklist above to identify which of your planned modifications require certification.

Can I get multiple modifications certified at once?

Yes. If you're performing several modifications simultaneously — such as an engine swap and transmission change — we can assess and certify all applicable mod codes in a single inspection, saving you time and cost.

What happens if I don't get a required modification certified?

Driving a modified vehicle without the required certification can result in defect notices, fines, registration cancellation, and voided insurance. It's essential to have all modifications properly certified with a mod plate.

How long does the certification process take?

Timeframes vary depending on the modification complexity. Simple certifications like child anchor points may take a day, while multi-code engine and drivetrain projects can take longer. Contact us for an estimate based on your specific modifications.
