While praising his team, Holdsworth paid tribute to Klimenko, who had finally scaled the top of the Supercars tree.
"I am also very proud of what Erebus has achieved... a race win and a very fast car. I am stoked," Holdsworth said.
"You guys all know [Betty] is out there.
"She is very different to the rest of us but she's awesome for the sport, bloody good to the fans with a massive following and she's good to work for."
With tears in her eyes, the charismatic and colourful Klimenko had finally reached the summit.
It would get even better in October 2017, but delivering the team's maiden victory in front of hardcore fans in Winton amplified her emotions.
"We are in a place where true fans come to watch; for me this is worth a hundred Homebushes or Townsvilles, because I'm standing in the middle of true fans who have come out here," she told Supercars.com after the race.
"We're a team that is sprung out of people. We're not a factory team, we're not even a Mercedes team, we're an Erebus team.
"We've worked hard. We didn't come in, in a blaze of glory; we came in and had to push the car backwards.
"I just remembered every face I've seen, every hand I've shook, every autograph I've given and it's just flashed before my eyes, I thought, 'Oh my God I must be having a heart attack’.
"But it's not just for me. It's for the boys, for the drivers, the people."
Winton will stage official pre-season testing on February 16, before hosting the fifth round of the 2021 Repco Supercars Championship across May 29-30.
The team's new-look driver line-up will make its competitive debut at the Repco Mt Panorama 500. Tickets are on sale now.
