Bathurst, if you've never come across it before, is Australia's greatest race track and home to the legendary Bathurst 1000 race. The track winds up the 'mountain' section before cascading downhill along the Conrod straight.
This video of a Porsche RS Spyder is filmed using onboard cameras and gives a fantastic feel for the speed the Porsche carries around the track. Particularly watch out for 1.50 when the car, travelling at 180mph, kinks right as it heads towards the chicane at the bottom of Conrod Straight. Awesome stuff.
