Five qualifying sessions over the weekend's racing and only seven sets of tyres saw Team BOC conserve rubber during today's practice sessions at Pukekohe Park Raceway.
Jason Bright finished 16th fastest overall after using only one set of the team's allocated tyres for the four sessions but was fourth and second fastest respectively in the first and second sessions when everyone was on the same tyres.
Team-mate Fabian Coulthard finished third-fastest overall so Bright is confident the car pace is there for tomorrow's first qualifying at 9.35am local time.
"There are two things that are going to win here: qualifying well and tyre life. It's definitely going to be a factor looking at the way everyone's tyres dropped off 1.2 to 1.5s over the course of today. Over a race that could be as much as two seconds.
"After today we've got six sets of tyres going into qualifying and the races so everyone else can't afford to have any hiccups. Whether it pays off or not, I feel more comfortable with at least one back-up set. It's too risky otherwise.
"Our pace has been there all day. I've watched everyone else put greens on and gain 1.2 seconds. I would like to think we would gain at least a second, which would put us right up there.
"I think there's more in having a back up set of tyres than having the run today. Our time at the end of the session there was pretty competitive with anyone else running older tyres so I think we're there or thereabouts and Fabian proved that the cars are pretty close."
