Russell Ingall said it was great to finally have a test day, and concentrate on car speed.
"Over the first half of the year we have maximised the full potential of what we've had, which was basically the same car the team ran last year," Ingall said.
"But now other teams have moved on and we needed to do the same."
Until now, the Lucas Dumbrell Racing squad has been running a standard package fromTriple Eight Race Engineering, with the main focus on the team, which was restructured for this season.
But now, that focus has shifted to car development.
"This test was all about performance enhancement and new components, which the team have developed - it looks like a couple of them have definitely shown potential," Ingall said.
"We have to be mindful that we're never going to go out and find a second a lap, in today's environment we are only searching for tenths of a second, that will make a huge improvement to grid positions and I think that's all we're missing."
Ingall also revealed he wasn't the only driver of the car yesterday, with the team set to announce its endurance co-driver in the coming weeks.
The next round of the Championship plays out at Queensland Raceway, and Ingall is expecting a strong show with cars running solely on the team's preferred Dunlop soft compound tyre.
"I've done what seems like thousands of laps around Ipswich, the track probably isn't the most technical circuit with only six corners but with that you have to make every corner count," Ingall said.
"I've had a lot of success over the years, we'll also be back on the soft tyre which we've shown to be more competitive with the front runners so it's stacking up to be a good round for us."
