Scott Pruett held off a late-race charge from Max Angelelli to give the No. 01 CompUSA Chip Ganassi Lexus Riley team their first win of the season in the closest finish in Rolex Series history. Pruett and co-driver Luis Diaz had to fight failing power steering throughout the entire 2-hour and 45-minute Ferrari Maserati 400 at California Speedway.

Angelelli and Wayne Taylor started from 11th on the grid but worked their way up to second in the No. 10 SunTrust Racing Pontiac Riley. Third went to Mike Borkowski and Paul Mears, Jr. in the No. 6 Michael Shank Racing Pontiac Riley.

Diaz started the race from the pole, but Jorg Bergmeister took the lead on the first lap in the No. 66 Krohn Racing/TRG Pontiac Riley. Fabrizio Gollin also got past Diaz in his No. 77 Crown Royal/Doran Racing Lexus Doran.

Diaz had some bad luck in the opening laps when his power steering went out. He dropped back to fourth as Michael Valiante took over third in the No. 19 Ten Motorsports BMW Riley.

Just ten laps into the race, the first full-course caution began in what was to be a wild race with plenty of bumping and spinning. The caution was for debris on the track.

The race resumed four laps later and although Gollin took the lead briefly, it was soon Bergmeister out front again in the Krohn Racing/TRG car.

Valiante was the surprise of the race, and he was soon holding down second, giving Bergmeister a challenge for the lead. Diaz managed to work his way back up to third, despite the difficult steering.
