Dyson Racing, going for its third overall victory in the Rolex 24 At Daytona, had its cars running first and third after four hours of the 39th running of the endurance classic on a rainy afternoon at Daytona International Speedway.

Andy Wallace held a 21-second lead over Eric van de Poele in the Risi Competizione Ferrari, with Max Papis third in the second Dyson Racing Riley & Scott Ford. Running fourth was reigning Indy Racing League champion Buddy Lazier in the Robinson Racing Riley & Scott Judd.

Two of the early contenders were back in the running after visiting the garage for mechanical repairs. Brothers Jon and Joe Field ran in the top three throughout the first two hours before losing the clutch in their Judd Lola, while the new Doran Lista Judd Crawford started by Didier Theys needed a transmission replaced.

Attrition also plagued the American GT class, with the Team Amick Corvette, Comer Racing Corvette and Spirit of Daytona Beach Camaro all sent to the garage for lengthy repairs. This gave the class lead to the Tropic Zone Oldsmobile Cutlass.

Team Amick driver David Amick lost third gear in the transmission, then was unable to find first or second gears. Given the options, the team replaced the transmission.

The No. 2 Corvette of Frank Freon continued to lead in GTS, with the team car with a lineup including Dale Earnhardt and Dale Earnhardt Jr. remained fourth in class.

The Porsche Haus Nissan Lola continued to set the pace in SRPII, while former Formula One rainmeister Hans Stuck led GT in the JET Motorsports BMW M-3.
