The four-time race winner was himself once a young charge in an established squad, having raced out of the Walkinshaw stable prior to his BJR days.
Notably, a 24-year-old Percat combined to win the Bathurst 1000 on debut alongside Garth Tander, with the likes of Will Davison, James Courtney and David Reynolds also racing out of the Walkinshaw stables.
Having enjoyed his time under such established stars, Percat believes he has more to give to his young rising teammates at BJR.
"I'm trying to help them as much as I can," he told Supercars.com.
"I came through an era at Walkinshaw when their cars were really good. They have guys like Tander, Davison, Reynolds, JC.
"I was around those guys for so long, and I saw what they needed to win races.
"From mid-2019 to now, there's been a pretty clear direction at BJR with set-up and developing the car.
"I try to help Macca and Jack as much as I can, and now we've got Todd on for a second year, it'll be cool to see how he goes.
"I predict he'll go better this year, with a year under his belt with us. Hopefully the year runs smoother and there's less pressure on them to perform."
Percat was a standout driver last season, recording a career-best overall finish of seventh.
It marked another exponential rise for Percat in his time with BJR; after a disappointing first-up effort of 19th in 2017, he has reeled off championship finishes of 10th, ninth and seventh.
