Each kit has been ESC tested by Bosch Australia and complies with the ADR 35-05 “Sine with Dwell” requirements and fully certified under RVCS (Road Vehicle Certification System) by the federal Dept. of Infrastructure and Regional Development. 

Each GVM suspension upgrade is issued with a silver modification compliance plate fitted next to the OEM compliance plate, stating vehicle particulars and approval number issued as Second Stage Manufacture. The suspension modification and fixing of the silver modification plate MUST be done PRIOR to any other modifications and MUST be done PRIOR to the vehicle being licensed.
