G’day , We currently run a VZ HSV in the Australian Production Car series. The current CAMS rules require proof of any authorized upgrades available at the time a vehicle was released before they are allowed to be used on a car in the Category. In May 2005 HSV released an Brake upgrade package – Dealer Team Specs (DTS) which could be added to the Clubsports, R8s and SV 6000. I have found a press release on this site dated 25 May 2005 saying the package would be available from July 2005 but this is not proof enough for CAMS. I need to find a dealer brochure , or a letter from the manufacturer to prove the DTS was in fact offered as a factory package and was in fact available at the time of purchase . Can anyone help? Thanks
