The Dutch driver also claimed the victory in both races on the last day of Formula 4 that took place at the Navarra circuit.
He was accompanied on the podium, both times in second place, by his teammate Oliver Goethe (MP Motorsport).
In the first race of the day it was Fluxá (Global Racing Service) who got to the third place of the podium after fighting for the second place against Goethe and Carles Martínez (Formula of Champions). Carles, meanwhile, had to settle for fourth position.
Nevertheless Carles Martinez had to retire in the last race where the podium was completed by Dufek (MP Motorsport), who had taken pole position in qualifying training for the last race of the day.
An almost perfect day for the MP Motorsport team closes with 5 drivers on the podium and with an indisputable protagonist of Kas Haverkort.
