Porsche Biggest Winner in Spa Pre-Race BoP Tweaks

Porsche has been the biggest winner in a pre-race Balance of Performance change ahead of the CrowdStrike 24 Hours of Spa in which seven of the ten GT3 brands received weight breaks.

The Porsche 911 GT3 R Evo had its minimum weight reduced by 15 kg on race morning of the blue riband round of GT World Challenge Europe powered by AWS and Intercontinental GT Challenge after the best of the German cars ended up only 16th in qualifying prior to a swathe of penalties.

The next biggest beneficiaries of the revisions to the BoP were the McLaren 720S GT3 Evo, the Mercedes-AMG GT3 Evo and the BMW M4 GT3 EVO with 10 kg reductions in minimum weight.

Its quickest representatives were respectively second, fourth and 18th in the original qualifying times.

The Aston Martin Vantage GT3 Evo, the Ford Mustang GT3 EVO and Lamborghini Temerario GT3 all received 5 kg reductions in the new BoP.

That means only the Ferrari 296 GT3 Evo, the Audi R8 LMS GT3 Evo II and the Chevrolet Corvette Z06 GT3.R will race at the same weight at which they qualified.

There were only minor changes to the turbo boost curves and engine air restrictors of the cars on Saturday morning.

Boost levels for the BMW and the Lamborghini were tweaked upwards and Ford received a small restrictor break.

Ferrari dominated qualifying, the No. 51 AF Corse Ferrari driven by Alessio Rovera topping each of the four segments of Friday’s Superpole session.

The Italian manufacturer’s new-for-2026 Evo version of the 296 was also quickest in two of the free practice sessions and first qualifying on Thursday.

The No. 50 AF Corse entry qualified third in Arthur Leclerc’s hands, only to lose its times because its data-logger was found not to be connected in post-qualifying scrutineering.

A final grid for the 24H Spa has yet to be released but the car will be line up near the back of the 32 cars that made it through to from first qualifying on Thursday to Superpole along with three others that lost their times, which included both Astons that had made the last 32.

The green flag for the 79th running of the race is due to fall at 4:30 p.m. CEST (10:30 a.m. EST).
