However, by this time Panoz had become frustrated with their new LMP07 following several disappointing performances, when it was decided following Le Mans that the team would bring back their LMP-1 Roadster-S. One car finished on the podium on its return debut before following this with a race win at Portland ahead of the Audi R8s. A second at Mosport was followed by another win at Mid-Ohio. However the team would suffer difficulties at Mazda Raceway Laguna Seca and the Petit Le Mans, leaving them off the podiums. Panoz's combined points between the LMP07 and LMP-1 Roadster-S would earn them second in the LMP900 championship, once again behind Audi.
