Defending Pro Am champions Graham Johnson, and Mike Robinson came through from 13th to claim their first GT4 win of the season, while Ben Tuck overtook two cars on the final lap to hand the Century Motorsport BMW M4 GT4 he shares with Ben Green a hard-fought second-place finish.
UltraTek Racing’s Kelvin Fletcher and Martin Plowman completed the podium.
The same Safety Car period that temporarily halted Optimum’s GT3 charge had a more significant impact on the GT4 result thanks to British GT’s handicap system.
Ben Green jumped Century Motorsport team-mate Dean Macdonald to lead the opening stint ahead of the second BMW, Tolman’s #4 McLaren driven by Charlie Fagg, both Academy Astons of Tom Wood and Will Moore, and Finlay Hutchison’s Equipe Verschuur McLaren 570S.
Ordinarily, the additional minimum pitstop time served by all Silver Cup crews is negated by their natural performance advantage over Pro Ams. But, with the Safety Car reducing their chances of building a sufficient gap, it was all change after the pit window closed.
Instead, Balfe Motorsport’s Mike Robinson emerged with a healthy class lead ahead of Martin Plowman’s UltraTek Racing Nissan and the Team Parker Racing Mercedes-AMG of Scott Malvern.
The trio began their second stint spread apart but were soon covered by just two seconds. Robinson managed to evade his pursuers long enough for Malvern’s increasing pressure to distract Plowman, whose attention switched from attack to defence.
While that allowed Robinson to re-establish a six-second lead by the chequered flag, Plowman and Malvern were soon joined in the fight for second by the same Century BMW that had earlier led the opening stint.
Ben Tuck had already passed Joe Osborne before setting his sights on the podium, and by the final lap, he was in a position to attack. First up was Malvern, whom he passed at Pilgrim’s Drop, before also relieving Plowman of second on the run to the line. Less than 0.2 seconds covered all three at the finish.
Behind, Osborne completed Tolman’s impressive comeback by finishing fifth after the team endured another very late night changing the #56 McLaren’s engine. A second PMW Expo Team of the Weekend Award in as many events was deserved once again.
Sixth went to HHC Motorsport’s Callum Pointon and Patrik Matthiesen who slightly reduced their deficit to championship leader Jack Mitchell. The Century driver did well to recover from the full 20-second success penalty, as well as the extra 30 seconds served by all Silver Cup crews after co-driver Macdonald handed the BMW over in second place.
Richard Williams and Sennan Fielding were best placed of the Pro Am runners before contact at Graham Hill Bend knocked their Steller Motorsport Toyota out of contention just before the pitstops. They recovered to finish eighth in the class ahead of Tolman’s Michael O’Brien and Charlie Fagg, and ProTechnika’s Anna Walewska and Tom Canning.
Academy’s hopes ultimately came to nothing, but their pace got rewarded with Matt Nicoll-Jones setting the Sunoco Fastest Lap.
All of that leaves Mitchell 10 points clear of team-mates Tuck and Green, with Matthiesen and Pointon a further 3.5 further back in third ahead of British GT’s Donington decider on 22-23 September.
