All three championships were still open when 49 cars took the green flag for 12 hours at Silverstone. Grid-and-Go.com eSports #1 led GT3 by 8 points from BS+COMPETITION #89, and a finish of 4th or better would make them champions whatever anyone else did. Grid-and-Go #901 and Bleu Mercure Esport #932 started level on 72 points in PCUP, with Impulse Racing #915 2 points behind. Team75 Bernhard by SimRC #475 led GT4 by 8 points and needed 5th or better.

Dino Lombardi put the #1 BMW on GT3 pole with a 1:57.203. The race started dry and in the dark, and Lombardi led the first hour with James F Beumee in the Falken Simracing Team #44 never more than 1.6s behind. Ryan van de Grijp started the Maniti Racing Green #78 from 6th on the grid and was 3rd by T+15m.

The wipers came on at T+1h20m. A minute later Grid-and-Go brought Lombardi in for wet tyres and fuel, the first GT3 team to switch. Beumee was then penalised for speeding on the way into the pit lane at T+1h24m, and Falken lost about 45s. By T+1h26m the #1 led by 9.5s.

The track stayed wet for 3 hours, with lap times about 20s slower than in the dry, and the #1 pulled further ahead. The lead was 17s at T+2h03m, 27s at T+2h30m and 34s at T+4h25m, with Jarno Koch driving from T+2h58m. Falken recovered from the penalty and were second by T+3h16m.

No one can touch Grid-and-Go in the wet.

The last rain band passed at T+4h21m, and the teams started planning the switch to slick tyres. Maniti ran the #78 for 23 laps on its wet tyres, then sent Tim Matzke out on slicks at T+4h58m. For the first lap his cold tyres made him barely faster than a GT4, but the timing was right. BS+COMPETITION came out right behind them on slicks but were 40s down on Maniti by T+5h01m.

Koch pitted at T+5h04m to cover Maniti's stop and brushed the barrier with his right front. After the 37s stop he spun, lost the main element of the rear wing and spun again in front of traffic. The #1 was still 3.6s ahead of Matzke at T+5h07m.

What do you expect when you lose the rear wing of your BMW M4 GT3? Do you expect to go faster? No. Maybe.

Koch kept Matzke behind for half an hour without the wing. The gap went from 3.5s down to 0.6s and back out to 2s, and at T+5h34m it was 0.06s. Matzke passed through GT4 traffic for the lead at T+5h37m, and Maniti Racing Green led the rest of the race apart from their pit stops. Koch pitted to repair the wing at T+5h53m and was still second after a 52.1s stop.

The #901 chased Bleu Mercure's #932 from PCUP pole at the start, and the two title cars touched at the final corner at T+22m while passing a GT4. Hady-Noah Mimassi took the #901 into the class lead in the rain at T+2h36m. After the next stops Altitude FreeM eSports #988, a team outside the title fight, led PCUP by 14s at T+4h03m with Jacob Tofts driving.

At T+4h16m Tofts came into Turn 1 three-wide and found a GT3 car stopped on the track. He had nowhere to go, and the crash ended Altitude's race. The #901 led PCUP after the stops at T+4h20m.

Bleu Mercure lost their chance at T+5h37m, the same minute Matzke took the overall lead. A replay showed the #932 going off hard into the tyre wall, and the booth said the #901 now only had to finish. At T+6h08m the booth worked out that Impulse #915 could still take the title on the tiebreak by finishing ahead of the #901. The Impulse car went nose-first into the barriers 17 minutes later and pitted for repairs.

This is the moment that has upended the championship.

Mimassi brought the #901 home 11th overall and 2 laps ahead of Fiercely Forward #912, the next PCUP car. Bleu Mercure finished 7th in class.

BS+COMPETITION started the day 8 points behind the #1 in GT3. Jannik Steinhoff was running second in the race when he got a black flag¹ for speeding in the pit lane at T+7h18m. At T+7h25m he hit a puddle and went off, and GT4 leader Adam J Isaksson in the Team75 #475 was caught in the crash. The #89 then spent more than 11 minutes in the pits and did not finish.

The #475 dropped to 9th in class with damage, and Team Checkmate Wolak Group #488 took the GT4 lead. Wolak had started the round 18 points behind Team75. If Wolak won and Team75 scored nothing, Wolak would be champions, because no team could drop its Silverstone score².

If more cars keep falling out of this race, they might stumble very much backwards through a hedge into the title.

Team75 rejoined about 3 laps down. At T+7h37m race control confirmed that a car had to complete half the overall leader's laps to be classified, and by T+8h06m the booth said Team75 had passed that mark. Konrad Zerebiec and Marcin Rybaczuk won GT4 for Wolak by 60.9s. Team75 finished 8th in class, and those 8 points kept the title.

The GT3 title was not safe yet. At T+7h04m Maniti led by 37.5s and the #1 was fourth. Maniti needed the #1 to finish 7th or lower to become champions. At T+7h06m Koch was pushed into the puddle at Brooklands while lapping Rybaczuk's GT4 and spun. Moments after that the Impulse Racing by TamLivery #57 Ferrari, third at the time, flipped over the tyre bundle and was out of the race.

The booth did the sums at T+7h13m. A Maniti win with the #1 in 6th would leave both cars on 86 points, and Grid-and-Go would keep the title on class wins, 2 to 1. Lombardi took over after a 92s stop at T+7h30m, and the #1 was 6th at T+9h02m.

By T+10h08m the #1 was the fastest GT3 on track. Lombardi passed Zero7's Lorenzo Castellani for third at T+10h18m. The next tyre stop dropped the #1 behind Castellani again, and Koch, back in the car and up to 2s a lap quicker, passed him before Copse at T+10h46m.

Van de Grijp took the chequered flag after 341 laps, 49.8s ahead of Falken. It was Maniti Racing Green's first win of the season. The #1 finished third, 92.9s behind, and Grid-and-Go won the GT3 title by 6 points.

Grid-and-Go #1 are GT3 champions on 92 points, 6 ahead of Maniti Racing Green #78, with BS+COMPETITION #89 third on 69. The #1 won at Motegi and Portimão and scored in every round except Adelaide.

Grid-and-Go #901 won PCUP with 92 points and 3 class wins, 11 ahead of Bleu Mercure #932 and 15 ahead of Impulse #915. Team75 #475 kept GT4 with 88 points and 4 class wins, ahead of Wolak #488 on 82 and Byte.Collino Max #444 on 79. All three teams were also the 2025 champions.

Yeah, I just messed up today, honestly. But it's good to know that we had the margin.
