Johnson is the grandson of Aussie touring car legend Dick Johnson and son of Steve Johnson, another Supercars stalwart.
After competing at state level in a Trans Am car last year, the 16-year-old is set to tackle the national series this season, starting at this weekend’s Race Tasmania event at Symmons Plains.
“The goal for me in Trans Am this year is to just get experience at the tracks I’ve never been to and get used to racing that is going a little more hip and shoulder,” said Johnson.
“I just want to get through the weekend cleanly, learn as much as I can and, obviously, have some fun.
“I’m not looking to go out and win every race. If I get in the top three, I’d be happy. But I need to learn the race craft and think about what I’m doing when setting up passing moves. It will be a whole new thing for me to be in a pack of good cars racing against each other.
“It will be interesting because you have a lot of people who are aggressive, pushing hard. The other Trans Am racing I’ve done is pretty cruisy, so it will be a good weekend of learning.”
As well as being his national Trans Am debut, this will also be Johnson’s first time at the Symmons Plains circuit.
“I’ve never been to Symmons Plains. In fact, I’ve never been to Tasmania before,” he said.
“I’m going to the track on Wednesday for a track walk and then help the team unload and get ready.
“If you look at the layout of Symmons, you’d think it’s simple, but it’s actually a pretty technical track, and then you are adding a whole bunch of other cars on the track, it will make for an interesting weekend.
“I’ve done some running on the sim which has helped me get my head around it, so I’m really looking forward to it.”
Johnson will join fellow sons of guns Ben Grice and Nash Morris in the 26-car field for the Trans Am season opener.
Nathan Herne returns to defend his 2021 title, while front-runners Kyle Gurton, Tim Brook and Owen Kelly have also signed on for the new campaign.
