The DBR9 won the Sebring 12 Hours for its LMGT1 category in 2005, but came third in Le Mans 24 Hour behind arch-rivals Corvette Racing due to fuel problems. In 2006, the DBR9 was unable to repeat its success at Sebring, finishing second behind a Corvette. A similar situation occurred at Le Mans as well. Despite not winning Sebring and Le Mans, Aston Martin Racing regularly challenged Corvette Racing for victory in the rest of the American Le Mans Series schedule, with victories at Lime Rock Park, Miller Motorsports Park, Mosport, Petit Le Mans, and Laguna Seca. Aston Martin capped their 2006 ALMS season by finishing second in the GT1 Manufacturer's Championship, earning the factory team an automatic entry to the 2007 24 Hours of Le Mans.
In the Le Mans Endurance Series, the Larbre Compétition took the Team's Championship, with victories at the 1000 Kilometres of Istanbul and 1000 Kilometres of the Nurburgring, a second place finish at the 1000 Kilometres of Jarama, and a fifth place finish at the 1000 Kilometres of Donington.
The DBR9 came into the 2006 FIA GT Championship being title contender favourites, but the season was somewhat lacklustre with only two victories at Mugello and Dubai. The Phoenix Racing Aston Martin DBR9 narrowly missed out on victory at the 24 Hours of Spa-Francorchamps. BMS Scuderia Italia cited a problem with finding the right tyre compound with their Pirellis as the factor for their lack of success.
For 2007, Aston Martin was finally able to overcome their woes at Le Mans, securing the GT1 class victory for the #009 Aston Martin Racing DBR9. Larbre's DBR9 would also manage third place in class. The teams running DBR9s managed to finish every car entered.
Later in 2007, Aston Martin launched the limited edition (300 units expected) DBS road car which has many styling cues taken from the DBR9 in conjunction with the James Bond film Casino Royale. Aston Martin Racing's DBR9s raced 2006 and 2007 under the numbers 007 and 009, in honor of James Bond.
In 2008, while Larbre and Scuderia Italia moved on from Aston Martin, Prodrive continued to field a two-car factory team at the 24 Hours of Le Mans. The #009 numbered car, with the new Gulf Oil sponsored paint scheme, driven by Darren Turner, Antonio Garcia and David Brabham, won its class.
