Shane Van Gisbergen: The best is still to come

It's enough to send shivers down rivals' spines.

Supercars defending champion Shane van Gisbergen reckons he can improve.

That seemed unlikely after the Holden star claimed dominant back-to-back wins in Adelaide to make a perfect start to the season on Sunday.

Yet the flying Kiwi warned fans ain't seen nothing yet.

"This weekend we had weird vibrations. It was a bit of a struggle," van Gisbergen said.

"The car is still very fast. It's just really uncomfortable.

"We've had big problems all weekend but we never fixed them but obviously the car is very fast - we will keep working away on it."

Van Gisbergen didn't look like he was uncomfortable behind the wheel all weekend.

The pole sitting Kiwi on Sunday pounced with just three laps left when race leader, Ford's Scott McLaughlin, locked up on turn nine in the second 250km first round event.

Van Gisbergen didn't look back, finishing 0.10 of a second ahead of McLaughlin with Ford's Chaz Mostert third in the second 78-lap event.

And he effortlessly claimed Saturday's season-opening 250km event more than 15 seconds ahead of McLaughlin's Ford teammate Fabian Coulthard.

It seemed there was no chink in flying Kiwi van Gisbergen's armour.

Yet he warned there was plenty of room for improvement.

"It's very uncomfortable knowing there's something not right with the car," the 2013 Adelaide champion said.

"We need to fix that and make it better."

Van Gisbergen still jumped to the top of the Supercars series standings with a perfect 300 points haul.

He leads Coulthard and Holden's James Courtney (both 249 points) ahead of next month's second round in Tasmania.

Much to SVG's team manager Mark Dutton's surprise, it seems, after an ordinary test day barely a week before the season opener.

"It wasn't a secret that we had some issues with the car (at Sydney testing)," Dutton said.

"We had some noise in the test day we couldn't put our finger on and had hoped we'd fixed it coming here this weekend.

"But it developed some other problems like vibrations and that was from rollout on Friday (in Adelaide).

"To put all that aside and to work through it, it's full credit to Shane."

In contrast, van Gisbergen's Holden teammate - six-time series champion Jamie Whincup - had a frustrating weekend.

He finished sixth in both season-opening races to place sixth in the drivers' standings ahead of the Tasmanian second round.
