Jonny Adam and Graham Davidson took a nervy British GT victory on Sunday afternoon at Donington Park.
The TF Sport Aston Martin led from pillar-to-post but through the two-hour race had to contend with pressure from Rob Bell and Shaun Balfe in the Balfe Motorsport McLaren, despite the efforts of the lapped Nicki Thiim to act as a rear gunner for Adam in the second stint.
Jonny Cocker took an impressive if slightly lonely third position for the Barwell Motorsport Lamborghini he shares with Same De Haan, while Michael Igoe and Dennis Lind in the RPI Lamborghini held off Phil Keen and Adam Balon in the second Barwell Huracan.
Ross Gunn and Andrew Howard were sixth in the Beechdean Aston Martin ahead of the JRM Bentley duo of Rick Parfitt Jnr and Seb Morris, with Ben Green and Dominic Paul completing the top eight.
It was another disappointing day for the lapped Mark Farmer and Thiim, with Farmer once more having a difficult opening stint after further contact on the opening lap dropping him to the GT4 pack, with further spins eventually seeing the Aston Martin drop a lap behind.
In GT4, it was another pole victory as Seb Priaulx and Scott Maxwell converted top honours on Saturday into victory on Sunday, although the MultiMatic Mustang duo did it the hard way.
That was thanks in no small part to the Tolman Motorsport #4 of Josh Smith and James Dorlin making the early running as they did in Silverstone two weeks ago.
As with Silverstone, trouble was never far away as contact with a GT3 Lamborghini broke a toelink and ended their race from the lead of GT4.
Maxwell had fallen back behind the HHC Motorsport McLaren of Callum Pointon, with Jan Mathiassen in the 42 Century BMW also proving a nuisance.
Pointon would eventually be dealt with by both men and Maxwell set about Smith in the McLaren before handing over to Priaulx.
Matthiasen would hand over to MArk Kimber and the BMW would emerge ahead of the Mustang, where Kimber would stay for much of the race.
The 17-year-old was putting up a fight despite having never driven the circuit before, but it took one mistake to allow Priaulx through with ten minutes left.
It would unravel for Kimber from there as brake failure ended his race on the penultimate lap to lose second place to Dean MacDonald in the #57 Championship leading McLaren while Lewis Proctor and Jordan Collard took third for the #5 Tolman McLaren.
