Richie Stanaway is 'still quietly confident' he and Garry Rogers Motorsport can put together a strong 2019 Supercars season after a low-key start in Adelaide.
Stanaway joins the Holden squad this year, having split with Tickford Racing at the end of a difficult 2018 rookie campaign.
Under the new Boost Mobile Racing banner, Stanaway finished 18th each day at the Superloop Adelaide 500, having started 18th and 19th.
That leaves him 20th in the standings after the opener but encouraged by improvements to his Commodore from race to race.
"We made the car a lot better from [Saturday]," he said of the Sunday race.
"We made a few changes overnight, which were much better, showed some promise but unfortunately didn't quite see that in the results.
"I'd be lying if I said I wasn't a little bit disappointed with where we've ended up this weekend, but I'm still quietly confident we can have a good season with some of the rounds coming up.
"We just have to put our heads down and see where we can improve and work really hard on getting some strong results at the next round in Melbourne."
Stanaway noted after the pre-season test at Phillip Island that the shift from a Tickford Falcon to GRM Commodore was more pronounced than he had expected.
Team-mate James Golding is 18th and nine points ahead in the championship, having taken the new-look squad's best race result of 14th on Saturday.
His grid positions mirrored Stanaway's, and Golding ran an alternate strategy on Sunday, winding up 19th.
"Definitely some positives to take away," he said.
"There was definitely a few spurts there where we had some really good speed.
"I'm looking forward to Melbourne, but I really want to try and chip away at the set-up with the guys and get a bit more speed out of it.
"We'll see what we can do there."
