The rule change for front air dam clearances, rear spoiler angle and rear spoiler size implemented for Sunday’s DuraLube 400 will be evaluated this week by NASCAR officials( That’s Racin’ Notes ) — NASCAR is not expected to change the rear spoiler size after last week’s race at Rockingham despite Ford’s dominance. The spoiler sizes were the same as used at the season-ending race at Atlanta last year. The spoiler heights are 6 1/4 inches for Fords, 6 1/2 inches for Chevrolets and 6 7/8 inches for Pontiacs. The higher spoiler sizes are meant to make the rear end of cars more stable and allow for more side-by-side racing( News and Record )
