TALLADEGA, Ala. – NASCAR announced two changes for today’s final practice session after 21 cars topped 200 mph in the opening practice session at Talladega Superspeedway.
NASCAR is having teams add a 1-inch wicker strip to the top of the spoiler.
NASCAR is allowing teams to switch between the two gear options (.345 and .350) until qualifying. Once a car qualifies, they must keep that gear in the car through the race.
NASCAR made the move after consulting with teams and drivers during and after the first practice session. NASCAR stated that there were some concerns with engines and officials saw speeds creeping up.
This is the first race at Talladega with this package, which included more than 100 more horsepower (to 550). NASCAR increased the spoiler an inch to 9 inches to help offset the extra horsepower. NASCAR also is mandating a 1-inch bolt-on track bar mount to change the height from 11 to 12 inches, raising the rear of the car by an inch.
