Qualifying was split into two rounds. The first round was held on Friday, September 10, at 5:30 PM EST. Each driver would have one lap to set a time. During the first round, the top 20 drivers in the round would be guaranteed a starting spot in the race. If a driver was not able to guarantee a spot in the first round, they had the option to scrub their time from the first round and try and run a faster lap time in a second round qualifying run, held on Saturday, September 11, at 3:00 PM EST. As with the first round, each driver would have one lap to set a time. For this specific race, positions 21-34 would be decided on time, and depending on who needed it, a select amount of positions were given to cars who had not otherwise qualified but were high enough in owner's points; up to two were given. If needed, a past champion who did not qualify on either time or provisionals could use a champion's provisional, adding one more spot to the field.
Bobby Labonte, driving for Bill Davis Racing, would win the pole, setting a time of 22.130 and an average speed of in the first round.
