During a press conference for the Sprint All-Star Race in Charlotte, N.C. today, NASCAR vice president of competition Robin Pemberton confirmed the Sprint Cup Series would officially make the transition to the rear spoiler beginning with the Goody’s Fast Pain Relief 500 at the Martinsville Speedway. Pemberton said 83 spoilers had been sent to the teams on Monday.
Teams tested the new rear spoiler on Tuesday at the Talladega Superspeedway, where the cars reached speeds well over 200 mph in the draft. Throughout the test, NASCAR tried different combinations of spoiler height and restrictor-plate size. Next week there is a two-day (Tuesday and Wednesday) test planned at the Charlotte Motor Speedway, where over 50 teams are scheduled to participate.
Along with the return of the rear spoiler, Pemberton explained NASCAR is still working on other changes to the aero package on the Sprint Cup cars that will go into effect at all the tracks, possibly starting as soon as Texas in April.
