of three races in the Challenger Round, and remaining in the NASCAR Playoff rounds through 2017, after which the fall Cup date was eliminated. The speedway was the first for NASCAR to start the field in two groups under the warm-up laps to help set pit speed. The track also hosted open-wheel racing for seven years, hosting CART from 1992–1995, then the Indy Racing League from 1996–1998. One of the open wheel winners was Tony Stewart, who later won three NASCAR Cup Series races at the track as well. In 2000, the track was the site of a pair of fatal collisions which took the lives of two promising young drivers. In May, while practicing for a Busch Series race, Adam Petty perished when his throttle stuck exiting the second turn, resulting in a full speed crash head-on in the middle of the third and fourth turns. When the NASCAR Cup Series made their first appearance of the season, a similar fate befell 1998 Rookie of the Year Kenny Irwin Jr. For safety reasons, track owners decided to run restrictor plates on the cars during their return trip to the speedway in September 2000. This resulted in an uneventful Dura Lube 300 won by Jeff Burton, which had no lead changes. It was the first wire-to-wire race since the 1970s. The 2001 New Hampshire 300 was originally scheduled for September 16, the Sunday after the September 11 terrorist attacks. NASCAR initially announced that the race would be held as scheduled, but the event was postponed until November 23 of that year, which was the Friday after Thanksgiving. There was much concern about the weather, but race day turned out to be unseasonably mild. Robby Gordon won that race. In 2002, in an effort to increase competitive racing, the track's corners were turned into a progressive banking system, as the apron was paved and became part of the track, and the track's banking was varied from 4 degrees in the lower two lanes to 12% grade (about seven degrees). The addition of SAFER barriers to the corner walls was made in 2003. During the September 2003 SYLVANIA 300, an incident occurred at this track involving Dale Jarrett where his wrecked race car brought out a caution flag. At the time, NASCAR's policy was for its drivers to race back to the start-finish line to begin the caution period. This policy allowed
