TALLADEGA, Ala. (AP) -- NASCAR is testing spoilers at Talladega Superspeedeay.
Twenty-five Sprint Cup teams are at Talladega on Tuesday to practice with a spoiler on cars in place of the rear wing. The all-day session started with single-car runs, then switched to a drafting practice. Speeds topped 200 mph.
That required NASCAR to call the teams into the garage to change to a smaller restrictor-plate in an effort to decrease speed.
The spoiler could replace the wing by next week's race at Martinsville Speedway.
