KMR Sport's Alex O'Grady claimed his first win of the year in the second race of the weekend at Oulton Park.
The Irishman made a great start from pole, handled an early safety car restart well, and led home championship leader Fred Green, pulling away just a little in the final half of the race to take the chequered flag with a margin of 2.6 seconds.
Elite's Green and Hillspeed's Enzo Hallman secured their second podiums of the event in second and third places respectively.
After their exciting lap one battle on Saturday, this time around O'Grady immediately put Green in the shade at the start, building a strong margin around the opening lap. His charge was temporarily halted though after Douglas Motorsport's Dayton Coulthard and Pace Performance's Josh McLean came together at Cascades.
O'Grady's lead of approaching a second was wiped out by the resulting safety car, which pitted at the end of lap three. He immediately rebuilt a lead of over a second, and though that was trimmed back to eight tenths on lap five, that was as close as it got. O'Grady showed his class to pull away, generally with an advantage of around a quarter of a second per lap.
As O'Grady pulled away, Green had to keep an eye on his mirrors, with Hallman following closely. The duo were separated by little over half a second for much of the contest, with Green holding on to second with a gap of 0.422s.
Behind the podium trio, Fortec's Thomas Ingram Hill claimed his fourth fourth-place finish of the season, a second clear of Nitrous Competitions ADM Racing's Luke Hilton.
Elite's Matan Achituv and Pace's Torrin Byrne were next up, with the second Fortec of Franciszek Cegielski the top rookie once more in eighth, and just four tenths behind.
Hillspeed's Connor Willis finished ahead of the third Fortec of Jordyn Martin, who delivered her most impressive drive of the season so far. She climbed from 15th on the grid to 11th early on, and then passed Elite's Emmilio Del Grosso with three laps to go to claim the final spot inside the top-10.
The third and final GB4 Championship race of the weekend at Oulton Park is due to commence at 3pm UK time, with full live streaming coverage available on the official championship website.
