Brad Jones Racing has unveiled Nick Percat's livery for the Coates Hire Newcastle 500, a revamped scheme for returning major sponsor Timken.
Percat carried Timken schemes in Newcastle in 2017 and then at Winton earlier this year, both with bright orange bases.
For this year's finale, the bearings manufacturer's livery features a metallic orange to round out Percat's second season with the Holden squad.
"This year we head back to Newcastle knowing what to expect; a huge event with massive crowds and undoubtedly some nail-biting on track action in the final races," Percat said.
"The track is fun to drive, yet provides a pretty good challenge for drivers to get right.
"It’s fantastic to have Timken on board again for the finale. We’ve done a lot of work together with Michael [Pearson, managing director] and the Timken team this year.
"I’ve been able to take part in drive days for Timken staff and customers, tour them through the garages at the events, and they love the experience and interaction with the team.
"Timken are passionate about motorsport and I know they’ll be cheering us home for a strong finish this weekend."
Percat finished eighth and sixth in Newcastle last year, to move from 21st to 19th in the standings.
A more consistent sophomore BJR season has the South Australian 10th in the points, 83 ahead of team-mate Tim Slade.
Beyond the intra-team fight, BJR also leads a tight, three-way battle for fourth in the teams' championship.
"Even though it’s only Scott McLaughlin and Shane van Gisbergen in the hunt for the championship, there are still plenty of championship positions to be decided," Percat added.
"The teams’ championship is really close, so it will create some really good battles out there this weekend.
"Everyone is looking at who they need to finish ahead of in the fight for those positions.
"Where we finish overall sets us up for next year in pitlane, and we’re looking forward to getting back up the order.
"We’re currently in fourth with two teams close behind, and we’re ready to challenge those in the hunt!
"I’m looking to solidify my spot in 10th and then build on that again in 2019."
