“Gearheads” (*1/2 out of four) was a forgettable Redbox drama for lunkheads about a conflicted teen (Massimo Lista) who is trained by a grizzled mechanic (Jeffrey Carpenter) to overcome his fear of driving and compete to win a race in his hometown. Standard small-town drama involving sports underdogs, bullies, and a beautiful girl from the wrong side of the tracks won’t make anyone forget “The Dirt Bike Kid”, “Hoosiers”, or “Rudy” anytime soon.
