The final race of the weekend at Snetterton is due to start at 14.40, with Pace Performance's Josh McLean on pole.
Race three features a top-12 reverse grid from the qualifying result, meaning McLean lines up at the head of the grid ahead of Hillspeed's Connor Willis.
The second Pace Performance car of John O'Donnell starts third ahead of Fortec's Franciszek Cegielski, with Emmilio Valentino Del Grosso (Elite) and Enzo Hallman (Hillspeed) on row three.
Pace Performance's Torrin Byrne and Douglas Motorsport's Conor Grant are next up, with Grant's teammate Dayton Coulthard and Fortec's Thomas Ingram Hill completing the top-10.
Qualifying pole sitter Fred Green (Elite) and KMRs double race winner Alex O'Grady will start from 11th and 12th.
The remainder of the 27-car grid lines up in qualifying order, though Arden's Michael Koh has picked up a five place grid penalty for causing a collision with Lily-May Watkins in race two, and drops to 24th. The full grid is shown below.
