Elite Motorsport's Fred Green topped the final two sessions of the second day to end the first pre-season GB4 test quickest at Snetterton.
The Ginetta Junior graduate's effort of 1m48.380s in the penultimate session of the week was the fastest of the two days, putting him just under two tenths of a second clear of KMR Sport's returnee Alex O'Grady.
Enzo Hallman, eyeing a sophomore GB4 campaign with Hillspeed was third quickest, 0.131s behind the Irish driver and 0.025s clear of day one pace setter Luke Hilton, who had topped the times in session two this morning.
Douglas Motorsport's Dayton Coulthard has been an ever-present contender in the top-five this week, and ended day two in that position, ahead of Fortec's Franek Cegielski.
The second Elite Motorsport car of Matan Achituv was next up ahead of Hillspeed's Connor Willis, with Douglas Motorsport's Jason Smyth ninth.
Fortec's Thomas Ingram Hill, who was fastest in the first session this morning, completed the day's top-10.
Six different teams were represented inside the top-six for the second day running, pointing towards another supremely competitive season.
The vast majority of the 28-driver field set their best times in the third session, with only five drivers recording better times outside of that session. Pre-season testing resumes at Donington Park on 18-19 March.
