Tracy was signed by Team Kool Green for the 1998 season. The year was a struggle for the team and Tracy personally, as he finished no better than fifth in any race and ended up a disappointing 13th in the championship. The low points of the year came in Houston when he crashed out of second place after colliding with his teammate Dario Franchitti, leading to an altercation with team owner Barry Green when Tracy returned to the pits, and when, while leading the Marlboro 500, he spun out during a caution lap 3 laps from the finish.
