Following A tumultuous season, JGR made two major changes. First the team dumped its longtime manufacturer, Chevy, in favor of Toyota. Though the Japanese manufacturer flopped in its first Cup season, it gains instant credibility from the Gibbs name and driver Tony Stewart's record (two Cup titles); with near limitless resources, Toyota should get its first Cup win in 2008. Next, Gibbs signed former Hendrick bad boy Kyle Busch, who joins NASCAR's most dysfunctional teammates, Stewart and Denny Hamlin. (The two clashed so much on and off the track in '07 that Gibbs himself had to get involved.) The key to success will be keeping all those egos in check.
