Problems with #99 rear housing?

Jeff Gordon would like NASCAR to look into the way Roush Fenway Racing is adjusting the rear housing on Carl Edwards' #99 Ford to create a competitive advantage. Edwards has won three times on 1.5-mile tracks this season and was in position to win a fourth before having late engine problems. Many in the garage said during testing at Lowe's Motor Speedway earlier this week that the yaw created — Edwards' car appears to be going sideways on the straightaway, creating more side force heading into the turns — by turning the rear housing to the right gives Edwards a competitive advantage. " … NASCAR knows it's happening," Gordon said on Friday at Darlington Raceway. "They are the ones that see the cars come through inspection. They see it. When cars can't even get on the scales because they're running sideways, it's something they need to address." Series director John Darby said there are no plans to further police the rear housing adjustment, noting NASCAR already has a rule restricting more than a quarter-inch change plus or minus. He added that Hendrick Motorsports, for which Gordon drives, was the first to experiment with the rear-housing adjustment on the new car and that Edwards' #99 team was one of the last. "They [complain] when we've got too many rules and then they want us to create more," Darby said of teams in general. "The process is so simple. There are limits on how far they can go."
