Competitors worked hard last weekend at Mount Panorama to beat their times during Challenge Bathurst.

Many teams used the four-day event to test their machines against the mountain, other professional outfits used the event to test vehicles before February’s 12-hour endurance race.

Despite the wet track during a couple of days, drivers used the climatic constraint to test tyres and prepare for the many conditions the mountain can throw at drivers.
