For a 21-year-old, Corey Heim is mature as they come, especially behind the wheel of a racecar. The Marietta, Georgia, native didn't win Friday's NASCAR Craftsman Truck Series race at Charlotte — he finished last after being disqualified in post-race inspection — but the way he handled the race itself was a thing of beauty. Here is the rule that shows three missing or loose lug nuts is a DQ.

com/g3CD2L9nfV Heim qualified second on Friday, starting alongside his TRICON Garage teammate, Tanner Gray. It didn't take long for Heim to take the top spot, however, and he easily drove away from the field to win Stage 1. Heim again grabbed the lead and drove off in Stage 2, but Gray did at least keep Heim's No.

11 Tundra in view. After winning Stage 2, Heim once more grabbed the lead on the ensuing restart, and with the best truck in the field at his disposal, he seemed primed to drive off into the North Carolina sunset. However, it seemed that fate was getting a little bored of seeing the Truck Series championship favorite have his way with the field.

After a caution on lap 81, Heim was relegated to the back of the pack when the field came down pit road, as a broken jack forced the fastest truck in town to sit and watch as its competitors roared by. Stuck outside the top 20 with just 47 laps to go, it seemed that Heim's bid for victory was over. Heim apparently decided that it wasn't.
