Controversy arose Thursday at Daytona International Speedway when 16 Sprint Cup teams were found to have modified roof flap spacers, which are against NASCAR rules.
According to numerous tweets and media reports, NASCAR confiscated all the improper spacers.
Early Thursday evening, it was learned that 15 additional cars on the NASCAR Nationwide Series also had their roof flap spacers confiscated.
“The manufacturers supply you with a kit for the spacers on the roof flaps, and these 16 cars were not in compliance,” NASCAR spokesman Kerry Tharp said, according to a report by USA Today.
Cars listed as possessing the improper equipment are those of Jamie McMurray, defending Sprint Cup champion Brad Keselowski, Marcos Ambrose, Denny Hamlin, Casey Mears, Clint Bowyer, Greg Biffle, Ricky Stenhouse Jr., Kyle Busch, Matt Kenseth, Trevor Bayne, Joey Logano, Aric Almirola, Michael Waltrip, Martin Truex Jr. and Carl Edwards.
All 16 teams were prevented from taking part in Thursday’s first practice session, but were eventually allowed to join the 90-minute period after proper spacers were installed.
Nine of the 16 Sprint Cup cars are Fords, six are Toyotas and just one is a Chevrolet.
Nationwide Series drivers whose cars had their roof flap spacers confiscated included those of Bayne, Reed Sorenson, Brian Vickers, Jeffrey Earnhardt, Dexter Stacey, Michael Annett, Cole Whitt, Mike Bliss, Robert Richardson, Jason White, Blake Koch, Landon Cassill and Travis Pastrana. Sprint Cup drivers who will be competing in Friday’s Nationwide Series race that also had the roof flaps on their NNS cars confiscated included Matt Kenseth and Kyle Busch.
Roof flaps are similar to airplane flaps, in that once deployed they are used to slow a car down, and particularly in the case of a spinning car, to keep it from becoming airborne.
There is no word what, if any, penalties will be handed down by NASCAR officials.
A.J. Allmendinger led all drivers in the first practice with a top lap of 200.218 mph.
