Stanaway pursued the drive himself - getting in touch with Super Black to try to piece a deal together.
"I wanted to get into the enduros so I reached out to them initially and then communication sort of bounced back and forth from there. We met up a couple of times and I looked at my existing racing plans to try to figure out if it could work or not.
"I am really happy to get it confirmed and I am really looking forward to getting some laps in the co-driver session this weekend."
Stanaway had his first day with the team yesterday and will get out on track for the first time behind the wheel tomorrow. He knows it won't be easy adjusting from open wheel and sports cars in Europe to big, heavy V8s.
"I had a sit in the car and ... got familiar with it. I am probably going to be able to learn a lot just ... watching over everybody's shoulder over the weekend.
"We get a half-hour session on Friday ... and then I get a full day of running on Tuesday next week.
"The last time I drove a V8 Supercar was three years ago and it wasn't in a competitive environment. I am definitely not under-estimating the challenge of getting my head around the car.
"In my opinion the V8 Supercars is one of, if not the best championships in the world in terms of how competitive it is and how professional the teams are."
