The final race of the weekend at Donington Park is due to commence at the slightly later time of 16.35, with Elite Motorsport's Kyuho Lee on pole.
The grid line-up for the event finale is a reversal of the top-12 of the combined qualifying result. Lee had qualified 13th, but due to a qualifying penalty, moved up to 12th in the amended classification and therefore starts at the front of the field.
He'll be joined on the front row by teammate Flynn Jackes, with Xcel's Rowan Campbell-Pilling and Hillspeed's Peter Bouzinelos on row two.
Patricio Gonzalez (VRD) and Abbi Pulling (Rodin) are next up ahead of Xcel's Luca Fluxa and Rodin's Maxim Rehm.
Arden's Leon Wilson and Rodin's Martin Molnar complete the top-10, with qualifying pole sitters Nikita Bedrin (VRD) and Deagen Fairclough (Hitech) 11th and 12th respectively.
