I'm sure you are aware of the Veloce Racing Association, a non AROCA, non CAMS affiliated ut incorpoated body interested in racing radial shod Alfa Romeos in NSW. I've just uploaded two files on the MG Festival of Sports Car event at Wakefield Park and a VRA team in the AROCA 6 Hour at Eastern Creek.
Here is our website: http://sports.groups.yahoo.com/group/VeloceRacingAssociation/
Not sure you that you can access much without being a member, but its pretty easy to join and costs nothing .... :)
