Ross cannot be beaten now as his closest points rival, Aucklander Clark Proctor, is not heading to this weekend's series final at Manfeild.
Competing at the Skope Classic motor racing meeting in Christchurch last weekend, Ross received the full force of the limelight for the first time this season.
At the first two rounds of the 2014-15 series in Australia late last year, it was Sydney-based Chevron B24 driver Tom Tweedie who set the pace and won the majority of the races.
At the two F5000 Festival meetings at Hampton Downs last month, it was super-vet Ken Smith (Lola T332) who qualified quickest and claimed a clean sweep of all six of the races.
However, with Tweedie only contesting the races in his home country, Smith choosing not to come south this year and Proctor having major gearbox issues in his March 73A/1 at the previous round, it was two-time former series winner Ross' time to shine.
The Dunedin man was by far the quickest right from qualifying, with his 1min 18.941sec pole time almost 1.5sec faster than Napier's Sefton Gibb (Lola T332).
In the first eight-lap race, Ross eased away to win by a comfortable margin.
''I was able to get enough of a lead and then it was just a matter of bringing it home,'' he said.
Ross looked set to romp away with two more wins on Sunday. He did, too, but not until he learned the hard way just how close the likes of Gibb and British-based series regular Greg Thornton (Surtees TS11) are now to his pace.
After grabbing an early lead in the morning's eight-lapper, Ross eased back, and paid the price, running off the track and being quickly bumped back to second by Gibb then third by Thornton.
''It was a lack of concentration, then I tried to push it a bit too hard,'' Ross said.
Gibb led the race for a total of four laps, with Ross getting back past Thornton for one lap, then losing the place and having to do it all again. In the end, he did get back into the lead, with Gibb second and Thornton third.
Ross made sure he did not make the same mistake in the 12-lap feature race, accelerating away to an early lead off the rolling start, winning from Gibb and Australian Paul Zazryn.
The sixth and final round at Manfeild this weekend has attracted a 15-strong field of F5000 cars spearheaded by Smith in his Lola T332. In the past, Ross has been one of the only New Zealand drivers able to foot it with Smith and he heads to Manfeild with one ambition in mind.
''I've got to beat old Kenny,'' Ross said, laughing.
