Valiante was based almost exclusively in sportscars since his spell in the Champ Car World Series. He moved into the Grand-Am series in 2006 and remained there until 2013, taking a couple of wins (Sonoma and Mid Ohio) along the way. In 2014, when Grand-Am merged with ALMS to become the United Sportscar Championship, Michael moved into that series, where he remained for the 2015 season. In 2016, Michael moved into the Continental Tyre Series. That year saw him suffer a serious crash which left him concussed. As it took some considerable time to recover, he is now retired. He mainly concentrates on his racing school and driving academy, his role as a driver coach and also that of managing the family-run karting team. He also works for Pfaff McLaren Vancouver as a salesman and test driver.
