Breen needed to win the final stage and claim the bonus point that put the title beyond the reach of Egon Kaur, who had led the standings from the opening round.
“It’s an amazing feeling,” said Breen. “I know I was the quickest driver over the whole series so to win is just brilliant.”
Egon Kaur said: “We had some damage to the filter mounting. We tried to fix it before this one and we also caught the car in front.”
