Richard Kerr beat Davey Todd to the opening race victory by 0.486 after a dramatic battle.
In a race which had been led for the most part by title hopeful Alex Olsen on the FHO Racing BMW, Todd had looked on course for the win when Olsen dropped back to sixth on the final lap but was unable to stop AMD Motorsport’s Kerr coming through.
Charlie Nesbitt finished third, a second further back as Billy McConnell recovered from running off track and re-joining 10th to finish the race fourth with Tom Ward fifth.
