CHARLOTTE, N.C. — They've got nine championships between them, and a combined five victories on the single most prolific day of racing of the year.
Dario Franchitti and Jimmie Johnson also share a friendship, even if it's from afar. They follow each other's races, text back and forth during the season and give the public a glimpse of their mutual admiration via Twitter.
They are, for the most part, the most decorated drivers over the last six years from their respective series.
Johnson's record run of five consecutive NASCAR Sprint Cup titles was snapped last season, but Franchitti won his third-straight title to make it four championships in the last five IndyCar seasons.
Both will be on the center stage Sunday for the biggest day of motorsports.
