Rory Butcher took his second win from two at Silverstone as he held off a chasing Josh Cook.
Once Cook had cleared Tom ingram in a thrilling race-long battle, he hunted down Butcher but couldn’t quite take the win.
Cook was however disqualified from the result for failing a ride height check at the end of race scrutineering.
The first of two safety car periods came on lap three when Nicholas Hamilton’s Cupra was in the gravel trap. He recovered and rejoined the race.
On the restart Josh Cook was battling Tom Ingram for second place. The pair were side by side from Brooklands through to Becketts. The Hyundai of Ingram prevailed and he maintained second place.
On lap nine there were two incidents to bring out the second Safety Car. Carl Boardley was tapped into Copse by Andy Neate’s Ford. Further back Jade Edwards and Gordon Shedden collided and not for the first time this season. Shedden tipped Edwards into the gravel at Brooklands and out of the race.
Racing resumed on lap 16 with Sam Smelt joining the list of retirements with a mechanical issue. It was round two of the Cook and Ingram battle on lap 17. This time Cook managed to squeeze past Ingram into Copse and went on the hunt for race leader Butcher.
Senna Proctor was next to join the list of retirements after contact going into Becketts. His team mate Cook however was closing in on Butcher, and was hot on his heels into the penultimate lap.
The final lap meant it was now or never for Cook. He made an audacious dive down the inside of Butcher into Brooklands, getting onto the grass, but Butcher held on for the win.
He took his second win of the day from Cook, Ingram came third with Colin Turkington behind him. Championship leader Ash Sutton finished fifth with team mate Aiden Moffat behind him. Dan Rowbottom, Chris Smiley, Stephen Jelley were seventh, eighth and ninth respectively with Jake Hill going from 21st on the grid to tenth.
