The final day of NASCAR Sprint Cup Series spoiler testing concluded at Charlotte Motor Speedway with Jeff Burton, driver of the No. 31 Richard Childress Racing Chevrolet, posting the fastest time of the day. Burton's time of 28.539sec/189.215mph paced the 49 cars from 40 Sprint Cup Series teams who took part in the two-day test.
Spoilers will replace the wings currently on the backs of NASCAR Sprint Cup cars beginning this weekend at Martinsville. Feedback from drivers on the second day of testing echoed the comments from the Tuesday session: The true test of the new spoiler will take place under race conditions.
"Personally, I would like to find out more about my car in traffic from someone close to me and how it may affect the car," said series champ Jimmie Johnson. "It's not going to be huge, but the first race or two there might be an opportunity at some of the bigger tracks. If you understand the car before anyone else does, you can put someone in a horrible spot and take advantage of them."
"We've had a very productive test and all of the RCR teams have learned a great deal of information," said Burton. "The cars drive a little different and the reality is that the conditions and the tire combination are different than what they were last year. So we're learning new things that we can apply to every race from here out and hoping that our test data will translate well over to race conditions."
"I noticed I didn't have to use as much brake as I normally did, so maybe there's a little more drag in the corner," said David Reutimann, driver of the No. 00 Michael Waltrip Racing Toyota. "It wasn't like you went out there and said, 'Man, this thing is completely different.' It wasn't a night and day deal."
"This is a pretty good place to test," said Roush Fenway's Carl Edwards of CMS. "It's nice and smooth and gives you a good idea of what your mile-and-a-half package is like."
"I really like the spoiler," Edwards added. "I think it's a great move. The fans are gonna like it and it doesn't seem to make the car feel much different."
The only incident of the day on track took place when the No. 22 Penske Racing Dodge driven by Justin Allgaier hit the wall, sustaining significant damage to the right front. Allgaier was unscathed but his car did not continue in the test session.
