'In disbelief': The shock Tasmania qualifying performer

Zane Goddard was the big shock from Sunday’s two qualifying sessions at the Beaurepaires Tasmania SuperSprint.

Tickford Racing’s Cameron Waters clinched the pole positions for Races 7 and 8, but the latter session saw Goddard qualify an outstanding fourth.

It marked a significant jump on Goddard’s previous best start of 14th, which he achieved on Saturday.

His previous best prior to the weekend was 16th at Sydney Motorsport Park last season.

"I’m sort of in disbelief," the Matt Stone Racing driver said.

"I thought the delta must have gone out of whack or something.

"The car just felt really good... I had a brush on the wall, maybe it tweaked something a good way.

"Car felt mega, I was sort of picking up on it this weekend; yesterday I was struggling a little bit, made some adjustments with my driving and the car was awesome.”

Goddard will share the second row of the grid with Shell V-Power Racing Team driver Anton De Pasquale, who scored a first podium for the team on Saturday.

Earlier, Goddard qualified 15th for Race 7, which will commence at 1:35pm AEST.

It marked another key milestone for Goddard, who topped official pre-season testing at Queensland Raceway in February.

Goddard praised first-year engineer Jack Bellotti for helping him make key gains across the early rounds of the season.

“It’s Jack’s first year, so he’s been doing a really good job on the radio,” the 21-year-old said.

“He’s never stressing out or anything, he’s always cool, calm and collected.

“It’s a good pairing."

Goddard will launch from the second row for Race 8 at 4:25pm AEST.
