Behind the top four, Jop Rappange, Ivan Jacoma and Theo Nouet got engaged in a fight for fifth overall, which allowed Lluc Ibanez to close. The #15 NM Racing Team rapidly closed the gap and after passing the #27 AGS Events Aston Martin in Tamburello, the Spaniard went after Ivan Jacoma.
The two went side-by-side into Tosa, but into Acque Minerali Ibanez hit Jacoma, causing suspension damage on the #718 Porsche. On the last lap, Ibanez had another coming together at Tosa. This time it was Jop Rappange who ended up facing the wrong direction.
