Toll Holden Racing Team's Garth Tander has admitted that they will need to do better at the next event at Winton Motor Raceway near Benalla, Victoria in two weeks time.
Tander was fourth outright in the City of Ipswich 400 this weekend - the seventh of 14 rounds in this year's championship - finishing P4 in all three of the 38 lap races that comprised the round.
With arch rival Mark Winterbottom taking the victory though, Tander now slips further behind the Ford man - although with seven rounds still to go and only 122 points between them, the 2007 V8 champion is still very much in contention.
"We struggled away all day and came home with two fourths to go with yesterday's. Our situation was the opposite too my team-mate's Mark [Skaife]; we good speed early, but no tyre consistency at the end," he explained.
"We need to have a look at the new tyre and try to improve in time for Winton in a fortnight."
Mark Skaife meanwhile finished the round in seventh, the five-time series champion losing vital positions in an incident with Steven Richards early in race 2 this morning.
Skaife finished Sunday's two races tenth and ninth respectively.
"Seventh overall for the round - it's disappointing to be back there," he continued.
"We had some dramas in Race 2 which put us back too far and our speed in the first segment on fresh tyres is not good enough. As a result our initial speed isn't good enough.
"There's some work for us to do before the next round, but the Winton is the Toll Holden Racing Team's home race and our goal is to go there and do a better than good job."
