Johnson will run a tribute livery to his grandfather – five-time Australian Touring Car Championship winner Dick Johnson, who famously fielded the Tru-Blu Ford Falcon XD in the early 1980s.
It won't be the first time that a member of the Johnson family has ran a tribute livery in honour of the family's patriarch with Jett's father, three-time Supercars race winner Steven Johnson running a tribute Tru-Blu Ford Falcon XD in Touring Car Masters.
“I'm really looking forward to kick-starting the 2023 Trans Am Series in the all-blue NAPA Mustang,” the third-generation racer said.
“All blue cars and my family have been linked for many years, not just with Granddad, but my dad (Steven) ran his Tru-Blu XD in Touring Car Masters in blue as well.
“It's a part of my family's history, and I hope the fans down at Symmons Plains like it.”
The 17-year-old is entering his second season in the National Trans Am Series off the back of his victory in the 2022 TA2 Muscle Car Series.
