Young gun Andre Heimgartner has emerged fastest from Friday practice ahead of Round 4 of the V8 SuperTourer Series at Hampton Downs.
The Holden driver lapped the 2.8km venue in a best time of 1:04.12s – some 0.35s quicker than that set in Friday practice for the opening round in February.
Fellow Holden driver Andy Booth came within 0.14s of Heimgartner's benchmark to end the session second fastest.
Manfeild round winner and series leader Jonny Reid was the fastest of the Fords in third.
Greg Murphy (Holden), Scott McLaughlin (Holden), Ant Pedersen (Ford), Craig Baird (Ford), Paul Manuell (Holden), Andy Knight (Ford) and Geoff Emery (Holden) rounded out the top 10.
The John McIntyre Racing Falcons of Steven Richards and John McIntyre managed just the 12th and 14th fastest times respectively, while series debutants Daniel Gaunt (Ford) and Angus Fogg (Holden) were 11th and 16th.
The top 13 cars were separated by less than 1s, pointing to a tight weekend of racing ahead.
A second practice session of 60 minutes duration will be held at 1000 local time tomorrow ahead of qualifying at 1300 and Race 1 at 1510.
