Drivers have turned into excited fans during the Supercars' historic first practice session in Sydney.
It's the sport's first weekend racing under lights in Australia since 1997's Calder Park round, with 60 temporary light towers around the Eastern Creek circuit.
After a disappointing season so far, Tickford Racing secured two podium spots as Chaz Mostert adapted best by pinching top position in the final seconds on Friday night.
Mostert's veteran Ford teammate Mark Winterbottom finished third behind Ford's Scott Pye.
A solid crowd turned out at Sydney Motorsport Park to witness the opening 40-minute session, with drivers and onlookers fascinated by the contrasting look and feel with daytime racing.
