Hamilton sprint car driver Dean Brindle's third place finish at WxC Speedway Western Springs on Saturday night was just enough to earn him the national series championship.
The 39-year-old overturned American-Kiwi Jonathan Allard's series lead to finally win the overall title, which has eluded him for a number of years.
Brindle finished third in Saturday night's feature race behind North Shore driver Michael Pickens in second and Jamie Larson from Palmerston North.
Brad Mosen kept up his winning ways in the midget division, claiming his fifth consecutive main event victory, as well as the overall series championship. Regular challenger Hayden Williams finished second ahead of his teammate Leon Burgess in third.
"Coming here every week I always feel so nervous, it's stressful and it winds me up, I feel sick, but as soon as I get out on a race track like that and just gas it up, there's no better feeling; that's pretty much as good as life gets for me," said 27-year-old Mosen.
