DAYTONA BEACH, Fla. (AP) — Thirty-one cars, including 16 in the Sprint Cup Series, failed inspection before practices at Daytona International Speedway.

NASCAR confiscated the teams' roof flaps and will inspect the devices, which are designed to keep cars on the ground during spins and high-speed wrecks. Penalties could be possible.

The cars involved included all three Joe Gibbs Racing entries (Kyle Busch, Denny Hamlin and Matt Kenseth), all three Roush Fenway Racing entries (Greg Biffle, Carl Edwards and Ricky Stenhouse Jr.), all three Michael Waltrip Racing entries (Clint Bowyer, Martin Truex Jr. and Michael Waltrip) and both Roger Penske Racing entries (Joey Logano and defending series champion Brad Keselowski). Cars driven by Jamie McMurray, Trevor Bayne, Casey Mears, Marcos Ambrose and Aric Almirola also failed inspection.

The roof-flap spacers had been illegally machined to reduce weight.
