Qualifying
Qualifying was split into two rounds. The first round was held on Friday, September 25, at 3:00 PM EST. Each driver would have one lap to set a time. During the first round, the top 25 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 26, at 11:45 AM EST. As with the first round, each driver would have one lap to set a time. On January 24, 1998, NASCAR would announce that the amount of provisionals given would be increased from last season. 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.

Ernie Irvan, driving for MB2 Motorsports, would win the pole, setting a time of 20.229 and an average speed of 93.608 mph.

Four drivers would fail to qualify: David Green, Gary Bradberry, Ken Bouchard, and Randy MacDonald.
