Bryce Fullwood set the pace in the opening Dunlop Super2 practice session at the Supercheap Auto Bathurst 1000, ahead of Saturday’s non-points 250km race.
Darwin native Fullwood turned a 2:07.5259 lap in his MW Motorsport Nissan Altima.
Fullwood displaced Paul Dumbrell at the top with his final lap, the points leader finishing just 0.0425 seconds adrift.
Todd Hazelwood was third fastest ahead of Fullwood’s team-mate Jack Le Brocq, Macauley Jones and Andrew Jones.
Jack Perkins, Will Brown and Kurt and Jake Kostecki - the only two-driver pairing in the field - rounded out the top 10.
Dumbrell, Hazelwood, Le Brocq, Macauley Jones and Perkins are performing double duties this weekend, contesting the Supercars race as co-drivers.
Super2 competitors will be back on-track on Friday morning for practice two at 10:40am.
