The outright category is dedicated to FIA Homologated GT3 vehicles only and broken into sub-classes based on driver qualifications.
GT3 Vehicles with three drivers of any classification. This is for fully professional driving squads and is most likely where the winner of the race will come from.
Cars in the Bausele Watches Pro-Am Class will feature either three drivers or four. In a three driver team, one driver must be ranked ‘Bronze’, if it’s a four-driver team two drivers must be ranked Bronze.
Pro-Am cars can contend for the race – only the drivers change, not the cars meaning that as long as your ‘Pro’ driver is on board, you’re going to be as quick as anyone.
Cars in the Silver class can have three or four drivers, all of them ranked either Silver or Bronze.
Cars in the Bronze class can have three or four drivers, all of them ranked Bronze.
Cars in this class are all the famous one-make Porsche 911 GT3 Cup Car, seen racing in Porsche Carrera Cup Australia and Porsche Sprint Challenge – and similar one-make classes all around the world.
THE GT4 class is for the latest boom category in global GT racing, GT4. GT4 cars are a step down in performance from their GT3 big brothers, making them more accessible for teams and drivers – both financially and from a driving perspective. GT4 cars compete in their own championship in Australia, however in major endurance races including the 12-Hour share the track with the GT3 machinery.
THE invitational class are for unique, one-off or unclassified endurance racing cars that don’t fit into the established GT regulations. This category is the home of the Aussie designed and built MARC Cars racers, plus GT2 machinery and other unique machines that keep the diverse nature of the race alive and well. Cars in the invitational class must comply to a 2 minute 6 second ‘benchmark’ lap time that they can not eclipse throughout the event.
