Brock Kidd - who sought to get his season back on track last time out in France as he dominated the weekend - was once again strong here with third, sharing the second row with Yakumi Takahashi ahead of a surprise row three in Aron Einarsson and Jawa Ahmad.
Keith Murphy, Felipe Cesar, Didier Arnaud and Jamie Gerrard completed an unusual top in a session which surprisingly saw no incidents, while the two drivers clear at the top of the championship - Nick Addison and Marcus Thunder - could only manage the sixth row, Thunder ahead of the Australian. Enzo Domenicalli also struggled, the Italian only managing eighteenth place.
Further rain is forecast for tomorrow which could see the race delayed, or even pushed back to Monday if conditions do not improve enough to allow racing to take place on the Rockingham oval.
