Leading drivers have questioned the format being used at the ITM Auckland SuperSprint at Pukekohe Park Raceway this weekend.
Four 100km sprint races have been scheduled with compulsory pit stops and strategy not a factor in the racing.
As a result, after a bit of jostling off the line and for the first lap or two, races have become a bit of a precession with limited passing opportunities around the track.
That goes against what happens at every other round of the championship. In years gone by two short sprint races were used on the Saturday with a longer Sunday race, where strategy became a key component.
The series moved this year to staging a single race on both Saturday and Sunday to better improve the contest, which has been warmly received.
