A record crowd at Brands Hatch saw Bridlington racer Senna Proctor come out on top in the final day showdown of the Ginetta Junior Championships.
After securing pole position, Proctor went on to win the race in front of 45,000 spectators.
Television viewers saw him secure the victory, which allowed him to leapfrog his rival Jamie Caroline.
But later in the day, Caroline’s HHC team protested about another driver’s jump start which now means that the title outcome will be decided in an MSA Court of appeal.
Senna’s father and manager Mark Proctor said: “Senna won the title fair and square, what HHC did is bad sportsmanship and quite simply not on.
“At the end of the day Senna outscored Jamie Caroline and took the title. Senna has behaved with total dignity in this situation and I am the proudest dad in the world.
“This championship will be the first of many for Senna as he is now well on the way to dream of competing in the British Touring Car Championship.
Proctor’s team boss at JHR Developments, Steve Hunter, said: “Senna is a superstar and deserves this title. We are very honoured and excited to have him in our team again next year.”
