This weekend's Sandown 500 serves as the first major hurdle Kiwi drivers Shane van Gisbergen and Scott McLaughlin have in their race for the 2018 Supercars title.
Van Gisbergen leads McLaughlin by 19 points but the pair is more than 300 clear of third-placed Jamie Whincup with just eight races left in the season.
The endurance events at Sandown and Bathurst, where double points are on offer, feature as the two races where the chasing pack can make significant ground in one fell swoop.
The fact co-drivers will also play a massive role in these next three rounds also acts as a championship wildcard and barriers that could really impact either drivers' chances of winning the title.
Shell V-Power racer McLaughlin has never won one of the big endurance events and would dearly love to taste victory in a major race over the next month while also boosting his championship position.
