"The track grip wasn't there and we didn't think we would get a good read.
"It was a good shakedown. There are always a few niggling things but they were all sorted.
"We had three new cars with no vibration issues so it has been a really good effort by everyone back at the workshop."
Lucas Dumbrell Racing's 16-year-old recruit Alex Rullo endured a tough initiation into Supercars racing at a similar test at Winton Raceway, crashing at turn four prompting the session to pause for 20 minutes while barriers were repaired.
Meanwhile Kiwi Chris Pither has been confirmed as teammate for Erebus Racing's Dale Wood for the Pirtek Endurance Cup this year.
Pither spent last year with Super Black Racing but was left without a drive after the Kiwi team gave up its Racing Entitlements Contract late last year.
