Dries Van Langendonck left Silverstone with a 72-point British F4 championship advantage after winning Sunday's final race, while Tommy Harfield took the reverse-grid contest.
Harfield delivered victory for Chris Dittmann Racing ahead of Virtuosi's Jarrett Clark. Hitech driver Chiara Battig completed that podium, her second top-three result of the season.
In the later race, Rodin Motorsport's Van Langendonck took his eighth win of the campaign. Chase Wherrell finished second, with Theo Palmer completing the podium.
The contrasting winners reflected the different opportunities offered by Sunday's two grids, but the larger championship gain belonged to Van Langendonck. His accumulated advantage put him in a strong position before the concluding Brands Hatch meeting on 10–11 October.
Silverstone consequently gave the series both a separate race winner in Harfield and a clearer picture of its title battle, with the decisive final weekend still to come.
