The #1 Triple Eight Race Engineering Chevrolet Camaro clocked a 2:06.8395s on its eighth lap of Mount Panorama before rain fell at the top of The Mountain.

David Russell was second in the #31 PremiAir Racing Camaro, just 0.1461s in arrears in the car he’ll share with James Golding.

Will Davison’s co-driver Tony D’Alberto was third and 0.6345s off the pace in the Shell-V Power-backed #17 Dick Johnson Racing Ford Mustang.

The inclement conditions meant the contest over who was fastest effectively ended just 20 minutes into the session.

Practice 1 pace-setters Walkinshaw Andretti United continued their speed into Practice 2. Ryan Wood’s off-sider Jayden Ojeda was fourth fastest in the Truck Assist-supported #2 Mustang.

Behind them, David Reynolds’ teammate Lee Holdsworth was fifth in the Tradie #20 Team 18 Camaro.
