Continuity mistake: When Hawk is drinking the Bourbon on the rocks, the lemon wedge disappears when he spits out, and re-appears after the scene when the lady giggles.
Continuity mistake: When Beth and Jam hit heads to pick up his drumstick, she is holding the stick in her right hand. Then next scene, she's rubbing her head with her right hand and holding the stick in her left hand. Then they go back to the original scene and she hands him the drumstick with her right hand.

Revealing mistake: When all four of the guys are driving the Volvo through Detroit, if you watch real close, sometimes you can see 1980's and 90's vehicles parked on the side of the roads. Especially when they show a long shot with an older mustang following them, there is what looks like (it's hard to tell) a newer Buick or Chrysler (like the 300m) on the left side of the screen.
Factual error: When the four boys are leaving the radio station, they hear "Escape (The Pina Colada Song)" by Rupert Holmes in the elevator. This would be impossible since the film is set in 1978 and that song wasn't released until 1979.
Continuity mistake: The scene where Jam's mom pulls out the K-mart box. At first, it's a newer K-mart logo, and then when the camera is overhead, it's a older logo.

Continuity mistake: In the scene where Trip throws the pizza out the window of the car, it is full daylight. When Hawk puts the rock on the pedal of Kenny's car to make it drive itself into the ditch, it is sunset. In the next scene, when the guys are celebrating, it is full daylight again.

Other mistake: Lex is in the backstage area and is being chased by a guard. He is walking around carrying a piece of drum equipment and he trips over a cord and drops it. But when the camera shot changes back to him the cord is nowhere to be seen, therefore he really tripped over thin air.
Continuity mistake: In the scene where Lex, Trip, and Hawk are in Lex's basement getting ready to go to school, there is a closeup of Trip hooking on a chain to the side of his jeans. In the next shot, the chain is hooked on to the front of his jeans.
