Tyler's CJ Fambrough served as a rear tire changer for Stewart in the Nationwide Series opener, the Camping World 300 at Daytona International Speedway.
Stewart thanked his crew and credited their speed in getting him out of the pits first close to the end of the race as a key factor in his victory. Stewart was the pole-sitter for the race.
On Sunday, CJ will work with Michael Waltrip's crew in the Daytona 500.
CJ is a member of Joe Gibbs Racing and trained at the NASCAR Technical Institute in North Carolina.
