It's the final Super Sprint event before the Pirtek Enduro Cup kicks off - and the V8 Supercars are back at Sydney Motorsport Park, a track that has been on and off the calendar in recent years.
There's no strong form guide - the new generation V8 Supercars haven't even raced here before - so it's anyone's guess who will come out on top at the 3.93km Sydney circuit.
Jamie Whincup has surged back to the top, finding form at Queensland Raceway and wrangling the Championship lead from Ford foe Mark Winterbottom.
However, it was Red Bull teammate Craig Lowndes who scored the most points at the last event. James Courtney won the big 200km, and the fifth and sixth placed players, Fabian Coulthard and Shane van Gisbergen are separated by just three points.
Predictions have pointed to all five manufacturers as big threats this weekend - and with a tight schedule on Saturday teams will be pushed to the limit to fine-tune the V8 Supercars to suit the finicky circuit.
For fans heading to the circuit, there are six sessions today - so ensure you head to Sydney Motorsport Park.
Don't miss a minute of the action, as 25 drivers battle it out for a potential 300 points.
