Championship leader Aaron Silvester will start this weekend’s race from pole after pipping newcomer Casey O’Gorman by a slender 0.017secs.
As the weather caused upset, Silvester sneaked in a 1min 18.765sec lap with two minutes to go to knock the former British Talent Cup champion down to second ahead of his first race in the class.
Third quickest was early provisional pole holder Owen Jenner, as Cameron Dawson ended the session fourth with Asher Durham fifth.
