Whilst it isn't something I'd recommend to a casual or beginner gamer, iRacing has had a Ford V8 Supercar for a while now and they have signed on for the rights to scan a Triple Eight COTF. They currently have Phillip Island, Oran Park and Mount Panorama as the Australian tracks on the service.
The main race each Monday night is broadcast live - well worth a look in:
