Kwasniewski, who became the youngest champion in the NASCAR K&N Pro Series West last year, became the first driver to win both titles.
Ranger had quite a battle on his hands because the rain cancelled qualifying. The starting order was set per the series rule book, therefore placing the Canadian back in 24th.
The 18-year-old started from the pole position and dominated the series’ inaugural visit to the 2.54-mile road course by leading wire-to-wire for his sixth win of the season.
Daniel Suárez crossed the line in second, in front of Bryan Ortiz, Andrew Ranger and rookie Cole Custer.
Kwasniewski also became the second driver ever to notch championships in two different series in consecutive years.
