British Formula 4 rookie Oscar Piastri continued to reduce Jamie Caroline’s advantage by winning the two main races at Snetterton.
The 16-year-old Australian topped qualifying for the first time and led home team-mate Ayrton Simmons in a one-two for Arden in the first race.
Piastri finished more than four seconds clear of Simmons, who spent the race defending from Linus Lundqvist and Logan Sargeant, who twice swapped places in the fight for third with the Swede eventually coming out on top.
In the finale, Piastri held off his fellow karting graduate Sargeant, who survived being hit from behind by Lundqvist under braking for Wilson on the first lap to wipe out Piastri’s early advantage and hound him to the flag, albeit without finding a way past.
Caroline started and finished eighth in race one, with an early move on Oliver York ultimately coming to nothing, with the Fortec racer getting back ahead, passing newcomer Olli Caldwell and finishing on the tail of Alex Quinn.
Eighth for Caroline did at least give him a place on the front row of the reversed-grid for race two alongside Manuel Sulaiman (the Mexican returning together with the JHR squad for the first time since team-mate Billy Monger’s accident at Donington).
Caroline got the lead at the start and built a two-second margin, before holding off York following a safety car restart.
From ninth on the grid, Piastri finished seventh, and after Caroline finished seventh in race three, he has cut the gap to the series leader to 46.5 points.
