The final GB3 race of the weekend on the Silverstone Grand Prix circuit is due to start at 16.55, with Arden’s David Morales on pole position.
The final race is the ever-dramatic reverse grid contest, with live streaming due to start at 15.25 ahead of the final GB4 contest.
Morales will aim to make amends after a tough weekend; the American missed most of the pre-event testing due to illness and has been making up ground since.
He starts ahead of Hitech’s Cian Shields, with Douglas Motorsport’s Tommy Smith and Hillspeed’s Nick Gilkes.
Zak Taylor (Fortec) and Bryce Aron (Hitech) form row three ahead of Taylor’s teammate and Oulton Park reverse winner Mikkel Grundtvig with Arden’s Alex Connor alongside the Dane.
Chris Dittmann Racing’s Branden Oxley and Carlin’s Javier Sagrera compete the top-10 on the reverse grid.
The fastest driver in qualifying and race one winner Joel Granfors starts from 20th and last, behind race two winner Tom Lebbon.
