Grove one-two in sole Sydney 500 practice, Wood last

The Penrite-backed pair were evenly matched to the tenth, with just 0.0252s splitting them after 45 minutes at Sydney Motorsport Park.

Jayden Ojeda was third and the best of the Chevrolet fleet for PremiAir Racing, 0.1138s off the pace. Fellow Camaro drivers Anton De Pasquale (Team 18) and Zach Bates (Matt Stone Racing) completed the top five.

Chaz Mostert led the Toyota Supra quartet in ninth, though his Walkinshaw TWG Racing teammate Ryan Wood languished in last.

The team said there were no issues with the #2 car, despite being 1.4 seconds off the pace.

The session ran without incident. Brodie Kostecki and David Reynolds each pushed the limits out of Turn 3 and sent dust skyward after running wide.

The session ended with a Safety Car procedure test and practice starts.
