Season review
The 2003 season brought substantial change at the pointy end of the series, with the era of the Holden Racing Teams dominance of V8 Supercar ending and the era of Stone Brothers Racing beginning. Marcos Ambrose form throughout the series was irresistible. From the series third round at Eastern Creek Raceway to the eighth round at Oran Park Raceway SBR Falcons took all six wins, Ambrose five of them with a second place behind Ingall at Queensland Raceway the only aberration. Ingall would win again in the Gold Coast street race with Ambrose confirming his championship at the Eastern Creek championship finale. Holden did not give in willingly, Mark Skaife and Greg Murphy each winning two rounds, with Skaife and Todd Kelly taking the reborn Sandown 500 as one of them, while one of Murphy's wins was Bathurst with his co-driver Rick Kelly becoming the youngest Bathurst winner. The only other round winner was Craig Lowndes had his first win for new team Ford Performance Racing.

Apart from the enduros, Stone Brothers Racing swept all before them with Mark Winterbottom dominating the Konica V8 Supercar Series in SBR's older AU Falcon. Winterbottom won four of the six rounds, the others were won by Andrew Jones and eventual series runner up Matthew White.
