Title contenders Scott McLaughlin and Jamie Whincup each set a fastest time in the two practice sessions at the championship finale on the streets of Newcastle today.
Whincup, who holds a narrow 30-point lead in the championship, was fast out of the gate as the street circuit made its Supercars debut in spectacular fashion.
New Zealander McLaughlin answered back in the day's second session however to set an impressive time.
While practice results count for very little it does suggest the two main protagonists should be among the front-runners when qualifying and the first race of the weekend takes place tomorrow.
"To be the fastest by a margin is nice but we've got a long way to go and we'll focus on it overnight," McLaughlin said.
