The V8 Supercars will hit the track for one final practice run before qualifying on the quick Hidden Valley circuit this morning.
With one qualifying session and one race on each compound of tyes today, drivers are expecting mixed results and a challenging run.
Throw in the new characteristics of the newly resurfaced circuit, and the effect of the UV on the track and tyres, and there are plenty of factors to face as teams and drivers push to top the timesheets at the SKYCITY Triple Crown.
