The Italian team would again take the FIA GT Championship crown in 2004, while Larbre Compétition won the GT1 class championship in the new Le Mans Series. BMS Scuderia Italia moved then to the Le Mans Series as well taking that championship for 2005. In the meantime Prodrive switched to their next project, the Aston Martin DBR9, leaving the maintenance of the 550 GTS cars to Care Racing Development. Hitotsuyama Racing entered a car in the 2004 JGTC and 2005 Super GT seasons, then switched to the Japan Le Mans Challenge winning the GT1-class title in both 2006 and 2007 editions. In 2008 Argentinian Automóvil Club Argentina Team entered 2 Prodrive 550's, one of them scoring and achieving the fifth place in the Potrero de los Funes round. The last race of the 550 GTS was the 2009 FIA GT Paul Ricard 2 Hours where a car entered by French team Solution F achieved the seventh place.
