In 1995 Giroix moved to high-level sports car racing with his own Giroix Racing Team that campaigned a McLaren F1 GTR in the BPR Global GT Series where he finished on the podium twice in five starts and competed in his first 24 Hours of Le Mans where his team finished 5th overall and 4th in class in a race uncharacteristically dominated by GT1-class McLaren F1 GTR's. In 1996 he split his time in Global GT between his own GTR and a factory Lotus Esprit. The Giroix McLaren F1 GTR failed to finish at Le Mans in 1996.
