South Australian John Goodacre made the most of his recently acquired 997 Cup Car to win the weekend's third round of the GT3 Cup Challenge at Eastern Creek Raceway.
The event saw three different race winners, with Roger Lago, Goodacre and Jeff Bobik each tasting victory across the weekend.
Goodacre, who had previously campaigned a 996, cemented the overall win with a second in Race 3.
“It was great to move up into the 997 and actually win the round. It's an unbelievable effort from everyone,” said Goodacre.
“I didn't think I'd be so quick straight away in the 997. We'd only had one practice in the car, so I thought I'd only make the top six. The win was a lot better result than I thought I would get.
“My aim is to get more round wins down the track. The more I drive the car, the more I get used to it. Hopefully I get quicker in it and improve the car throughout the season.”
Terry Knight took out the 996 Cup Class for the second round in a row, having recorded sixth, 13th and ninth outright in the three races.
Lago remains in the outright series lead after Eastern Creek round, ahead of Bobik, Goodacre, Morriss and Knight.
The Australian Saloon Car Series also boasted three different race winners at the Shannons Nationals presented by Hi-Tec Oils meeting.
Matt Lovell and Shawn Jamieson recovered from their exclusions in Race 1 to take a win apiece in Sunday's races, while the consistent Sam Milton left with the round honours.
Jessie Dixon, Rex McCutcheon and Allan Jarvis took turns to lead home the modest Australian Swift Racing Series field, while Darren Hossack, Russell Jamieson and Yiani Harpas shared the Superkart wins.
The Shannons Nationals continues at Morgan Park on August 12-14.
