Jack Kennedy took the Sprint race win by just 0.043secs over reigning champ Ben Currie as the pair fought to the line at the end of 10 laps.
Polesitter Currie had taken early control of the race as he hit the front with a stunning start as Kennedy passed Luke Stapleford to move into second position at Druids.
From there, Kennedy chased his rival for much of the race, keeping right on his rear wheel before hitting the front on Lap Seven. But Currie wasn’t going to give up easily and was back ahead by the next lap – and the battle continued to the final lap.
Currie was ahead as the pack started the last lap but Kennedy moved ahead into Paddock Hill Bend, before Currie took it back again. A small error by Currie let Kennedy back through towards the end of the lap and it was enough to keep his rival at bay, as the Honda Racing UK rider took the win.
Luke Stapleford was third rider home, with Alastair Seeley fourth and Richard Cooper fifth.
Mikey Hardie continued his strong run at Brands Hatch to take the Cup win, with Cameron Hall second and Adon Davie third.
And in GP2, Owen Jenner stormed to yet another win over Lucca Allen and Keo Walker.
