Scott Kin Lindblom and George Proudford-Nalder shared Sunday's British F4 victories at Donington Park, leaving the championship lead at just four points.
Hitech driver Kin Lindblom won the reverse-grid race and became the twelfth different winner of the season. Chase Wherrell finished second, with Virtuosi Racing's Jarrett Clark third.
Proudford-Nalder then took his second win of the campaign in the final race. The opportunity emerged after Tommy Harfield and Ethan Jeff-Hall collided at McLeans, allowing the Virtuosi driver to take control.
Ethan Lennon finished second in that contest and Wherrell returned to the podium in third. Those results kept Wherrell close to championship leader Dries Van Langendonck.
The meeting highlighted the breadth of the winning field as well as the narrow margin at the front of the points table. With several teams taking significant results, the remaining rounds offered little scope for the leading contenders to relax.
