Rees made his debut in the LMP2 class of the Le Mans Series in the second round of the 2008 championship, in Monza. In 2009, Rees signed once again with the Barazi-Epsilon team in the LMP2 class of the Le Mans Series. For this season, Barazi-Epsilon decided to run a two-drivers team, with Rees and Juan Barazi. But soon after the second race of the championship, in Spa-Francorchamps, the team announced its retirement from the 2009 Le Mans Series championship because of financial problems. Rees was left without a team to race for the remaining season of 2009.
