After a drama-filled finale at Donington Park, Barwell Motorsport secured a 1–2 finish to end the season on a high; but it was the 2 Seas crew of Charles Dawson and Kiern Jewiss who claimed the championship in spectacular fashion.

A dominant performance in changeable conditions, the #78 Barwell Lamborghini of Alex Martin and Sandy Mitchell took the chequered flag over 30 seconds ahead of the #1 sister car of Rob Collard and BRDC rising star Hugo Cook.

After securing a 1–2 in qualifying, the Barwell team ran a faultless race with their pair of Lamborghini Huracán GT3 Evo2s finishing the race with a 42-second buffer to the third-placed #18 2Seas Mercedes of Kevin Tse and ex-DTM Champion Maxi Gotz.

However, the #42 2Seas sister car of Dawson and Jewiss took the 2025 championship.

Coming into the Donington Decider, it was all to play for however a string of mid-race incidents ended the hopes of multiple cars…

The #42 first collided with the #7 Blackthorn Aston Martin of Giacomo Petrobelli and Jonny Adam, who were sitting joint second in the championship, sending both cars pirouetting through the wet grass.

Merely a few laps later, the #42 was again involved in a collision turning the #77 Optimum McLaren of Morgan Tillbrook and GT3 ace Marvin Kirchofer into the gravel with the stewards giving them a 10-second penalty.

The race finished early for the #77 McLaren when Tilbrook beached himself in the gravel on the run-up to McLeans bringing out a Full Course Yellow, prompting a sea of cars into the pitlane for a change of tyres.

Yet, despite all the mid-race carnage, the #42 battled through and still clinched the championship.

In GT4 it was not to be for the #71 Century Motorsport BMW of Ravi Ramyead and Charlie Robertson, as the #90 Optimum McLaren of Marc Warren and Jack Brown came out on top with the victory in the race, winning the overall championship rounding out the season on 200 points.

With the 2025 championship under his belt, Brown becomes the first person in British GT history to claim multiple GT4 titles, retaining his 2024 crown of which he achieved with the same Optimum Motorsport outfit.

The #97 Beechdean Motorsport Aston Martin of Andrew Howard and Tom Wood sealed the Silver-Am class championship with their fifth win of the season. The Sidemen sponsored car finished the race sixth overall, beating out Johnny Ip and the Bridger Motorsport Honda NSX for the trophy.
