With a realignment of ALMS regulations, the team moved their two largely unchanged Lola-AERs up to the LMP1 class for 2004. Weaver and Leitzinger took a memorable win at Mosport and the 16 and 20 cars between them accounted for eleven podium finishes. The Portland ALMS race was particularly hard-fought with Chris Dyson holding off reigning LMP1 champion JJ Lehto in the Audi R8 for more than half the race. The team finished the season 2nd in the championship with drivers James Weaver and Butch Leitzinger second and Andy Wallace third in the championship.
