15-hour update: did the leading Ferrari make a tactical mistake?

Not taking the mandatory Technical Pit Stop under Safety Car might cost the leading #51 AF Corse Ferrari dearly.

Shortly after the halfway mark, the rain over the Spa-Francorchamps increased. The leading trio immediately pitted to change to rain tyres, which erased the difference in strategy between the leading #51 AF Corse Ferrari and the #63 Orange1 FFF Lamborghini in second place. Some of the drivers inside the top 10 took a gamble by staying on slicks. That was the case for Maxime Soulet (#3 K-Pax Racing Bentley), Renger van der Zande (#29 Team Honda Racing) and Franck Perera (#163 Emil Frey Racing Lamborghini), but after three laps that cost them some 15 to 20 seconds a lap, they abandoned their plans.

With eleven hours to go a Full Course Yellow was called, after the entry to the endurance pitlane was blocked. With that being followed by a safety car, several of the teams in the top 10 used the opportunity to make their mandatory Technical Pit Stop. That stop must have a length of at least four minutes from pit-in to pit-out, and must be taken after the start of the 12th hour and before the end of the 22nd hour.

Crucially, the leading #51 AF Corse Ferrari did not take that Technical Pit Stop under the Safety Car, effectively wiping out their advantage on the cars that did. Those included the #63 Lamborghini and the #98 ROWE Racing Porsche (third at that time), but also the #4 Mercedes-AMG HRT, #40 GPX Racing Porsche, #3 K-Pax Racing Bentley and #29 Team Honda Racing.

Once the lights went green again, Nicklas Nielsen – who had taken over from Alessandro Pier Guidi in the #51 Ferrari – did his utmost best to increase the gap to the #63 Lamborghini of Andrea Caldarelli. Nielsen was helped by both Mathieu Jaminet (#12 GPX Racing Porsche) and the #66 Audi Sport Team Attempto of Patric Niederhauser, who passed the Lamborghini on their way to virtual podium finishing positions. Neither of them had taken a Technical Pit Stop during the safety car period though.

With 15 hours to go the #51 AF Corse has a narrow 3-second lead over the #12 GPX Racing Porsche, with the #98 ROWE Racing Porsche a further 30 seconds down the road. In Silver Cup the #5 HRT Mercedes-AMG extended its advantage on the #78 Barwell Motorsport (after the latter suffered a puncture), with the #93 Sky-Tempesta Racing Ferrari increasing its advantage in Pro-Am. The #108 CMR Bentley is still the best of the remaining Am Cup runners.
