Kostecki and Erebus Holden co-driver David Russell were contenders throughout Sunday's blue ribband event, sitting second behind eventual winners Shane van Gisbergen and Garth Tander for the middle part of the race.
Still sitting second with less than 20 laps to go, Kostecki had just served his final stop of the race when the race fell under caution thanks to Will Davison hitting the wall at Griffins Bend.
