If anyone is interested (there's one WRX STI in the field), the live stream is: http://www.bathurst12hour.com.au/ via Ustream. Race started at 06:15 (AEDT) and the feed was a bit jerky initially but seems to have settled down. For those of you with paytv (not me), it is being shown on FOXSports/SpeedTV I think.
It is currently dark in Bathurst so some lovely shots of glowing brake calipers.
Enjoy.
