Matthew Payne has claimed the Castrol Toyota Racing Series crown just a month out from making his Porsche Carrera Cup Australia debut.

The Kiwi capped off the three-round championship with three wins from four races at Manfeild Circuit Chris Amon in Feilding.

The young gun fell shy of sweeping the weekend after copping two five-second penalties for separate infringements in Race 3.

Payne incurred the first penalty after lining up outside of his grid and received the second for an infringement under Safety Car.

In what was a dominant performance, Payne fell just short of having a large enough margin. In the end, his nine-second advantage was cut, relegating him to second behind Billy Frazer.

Payne’s championship win was made all the more impressive as one of the least experienced road racers in the category.

Prior to contesting this year’s Toyota Racing Series, Payne has just six Formula Ford starts to his name.

However, the youngster has a handful of national karting championships to his credit and multiple international starts.

“It’s been such a crazy year, coming back from Europe last year after karting finished, then getting into a car has been difficult,” said Payne.

“This series has been so good, and I’ve learned a lot.”

Payne will join Earl Bamber Motorsport in Porsche Carrera Cup Australia this year in an entry supported by Porsche New Zealand.

“The endurance racing side of it is where I want to head,” Payne added. “Le Mans and Daytona are definitely races I want to compete in and get some good results.

“For now it’s off to Australia to see what I can do there.”
