''We're not going to stop analyzing the areas and what makes the most sense,'' Chitwood said. ''We're going to continue to work with NASCAR and their experts on what's the next improvements we can make here at Daytona. Based on the last couple of years and what we saw this year, we're not going to stop figuring out ways to improve the property.''

That includes the extra 4,000 feet at Daytona. ''As safety remains at the forefront, ISC will continue to work with NASCAR to evaluate specific locations inside the turns for future safety enhancements,'' ISC President John Saunders said. Busch would like to see removing grass at the top of the list. He even cited Ryan Briscoe's flip in the IndyCar Series last weekend. Briscoe's car got airborne after he slid into the grass.
