NASCAR officials are looking at whether the double-wide restarts used in the All-Star race with all the leaders up front should be used for regular Sprint Cup races. "We've been talking about it for a year," series director John Darby said on Thursday at Lowe's Motor Speedway. "Every time we have an All-Star race the frequency of those talks gets much louder. It's obviously something the fans like a lot. Their interest is our interest. We're looking at it." While most procedural changes are made during the offseason, Darby didn't rule out that a change could be made during the season if the governing body thought it made for better racing. "We use it in modified and Camping World East/West events," he said. "The only thing it hasn't applied to is the national series. What we have to look at is the downside. We try to apply every scenario that could create more problems. That's what we're working through." Races currently are started double-filed until 20 laps remain with lapped cars on the inside lane. That means a 15th-place car actually could be starting in the 30th position. All restarts 20 laps in are single file.
