In 1997 Giroix's team became the factory-backed outfit for the Lotus Elise GT1 in the FIA GT Championship but the season was not successful. In 1998 he only made one start in a Zakspeed Porsche 911 in FIA GT. Giroix drove in a handful of sports car races throughout most of the 2000s before resurfacing in the Speedcar Series in 2008 where he competed in all 8 races and finished 10th in points.
