The race was held on Sunday, February 21, 1999, in Rockingham, North Carolina, at North Carolina Speedway, a 1.017 miles (1.637 km) permanent high-banked racetrack. The race took the scheduled 393 laps to complete. In the closing laps of the race, Roush Racing driver Mark Martin would manage to pull away with nine to go to win his 30th career NASCAR Winston Cup Series victory and his first victory of the season. To fill out the podium, Robert Yates Racing driver Dale Jarrett and Joe Gibbs Racing driver Bobby Labonte would finish second and third, respectively.

The layout of North Carolina Speedway, the venue where the race was held.

North Carolina Speedway was opened as a flat, one-mile oval on October 31, 1965. In 1969, the track was extensively reconfigured to a high-banked, D-shaped oval just over one mile in length. In 1997, North Carolina Motor Speedway merged with Penske Motorsports, and was renamed North Carolina Speedway. Shortly thereafter, the infield was reconfigured, and competition on the infield road course, mostly by the SCCA, was discontinued. Currently, the track is home to the Fast Track High Performance Driving School.

Qualifying was held on Saturday, February 20, at 10:45 AM EST. Each driver would have two laps to set a fastest time; the fastest of the two would count as their official qualifying lap. Positions 26-36 would be decided on time, while positions 37-43 would be based on provisionals. Six spots are awarded by the use of provisionals based on owner's points. The seventh is awarded to a past champion who has not otherwise qualified for the race. If no past champion needs the provisional, the next team in the owner points will be awarded a provisional.
