GB3 points leader Callum Voisin topped Saturday morning’s practice session on Brands Hatch’s Grand Prix layout.
The Rodin Carlin driver set a time of 1m19.124s halfway through the 20-minute session and was fastest by 0.079 seconds over chief rival Alex Dunne.
Zak Taylor set an early benchmark of 1m23.917s for Chris Dittmann Racing, with Douglas Motorsport’s Lucas Staico soon going fractionally quicker.
Fortec Motorsports’ Max Esterson lowered the benchmark by 0.6s before Dunne lapped almost two seconds faster for Hitech GP with a 1m20.373s.
Voisin beat Dunne’s effort by almost 0.5s, and JHR Developments’ Matthew Rees briefly held top spot with a 1m19.659s before it was deleted for exceeding track limits.
Rees’ team-mate Joseph Loake took over in first place with a 1m19.615s as Tymek Kucharczyk, another to have a lap time deleted, movws into second.
McKenzy Cresswell, who set Friday’s testing pace on the shorter Indy layout, then edged Loake to first place by 0.078s, before Voisin recorded his practice-topping time.
Kucharczyk reduced Voisin’s advantage to 0.278s before being demoted to fourth by Dunne and Cresswell.
Dunne had his improved laptime deleted, relegating him back to fifth, but he made his final lap of the session count to grab second as the chequered flag waved.
Loake also improved on his final effort to end the session fourth behind Cresswell, with Kucharczyk fifth ahead Rees, another to go quicker at the end of the session.
JHR’s David Morales had a trip through the Paddock Hill Bend gravel trap but was able to rejoin and subsequently went seventh fastest.
Oliver Stewart improved on his final lap to take eighth ahead of Jarrod Waberski and Costa Toparis.
