Matthew McCutcheon will drive one of the squad's Triple Eight Race Engineering-built VF Commodores in the third tier of Supercars this year.
He finished the season as runner-up driving the sister car to the van Gisbergen championship-winner which was being run by Shane's father Robert and his team.
Shane himself was analysing data and vision in order to provide feedback from Australia.
After then cutting laps with the latter at Winton, he has now been named as one of its drivers for the 2023 season.
“In our first discussion with Matt, he didn't just say he wanted to be a Supercar driver, he said he wants to be a Supercar champion,” explained Team Owner & Manager Rachael Eggleston.
“We know he will leave no stone unturned to get to the top level of Supercar racing in Australia and we cannot wait to be a part of helping him get there.
“Matt and his family flew to the Adelaide 500 where Matt worked with the team, he wasn't afraid to get his hands dirty and was doing everything from cleaning cars, tyre pressures, and everything in between.
“It was a great opportunity for him to learn how a race weekend in the category works and get himself ahead of the game for 2023.
“He had a test with us in December and showed real talent behind the wheel. He worked so well with the team to get faster and faster as the day went on.
“He has such a fantastic attitude and is just a great young guy. We are genuinely excited to hit the track and we are confident Matt will be a regular podium contender.”
McCutcheon himself, a Tony Quinn Foundation scholarship winner, said, “I am so excited to be joining Eggleston Motorsport in 2023 to race in the Super3 Series.
“I can't thank Ben [Eggleston], Rachael and the team and all my supporters enough for this opportunity.
“It has always been a dream of mine to race in the Supercar series and this step is an amazing opportunity in achieving my goal of racing in Supercars.
“After spending time with the team at the Adelaide 500 and then again at the test at Winton a couple of weeks after, I already feel at home and I am honoured to be a part of their winning team.
“I can't wait to kick off the season at Newcastle which is coming around fast.”
Round 1 supports the Thrifty Newcastle 500 on March 10-12.
