More changes come to NASCAR All-Star Race
By AMANDA VINCENT
The race format isn’t the only thing changing about Saturday night’s NASCAR Sprint All-Star Race and Friday night’s Sprint Showdown exhibition events at Charlotte (N.C.) Motor Speedway. Efforts are also being made to, again, lower the downforce and side force on the race cars.
“We really need to thank (Charlotte Motor Speedway President) Marcus Smith, here, because, when we do some of these things, we want to make sure the tracks know the package is coming. They’re supportive,” NASCAR Senior Vice President of Innovation and Racing Development Gene Stefanyshyn told NASCAR.com
. “Marcus has been very open-minded to help us try some of these things. Everybody plays an important position, here; we all want everybody together.”
The mandated welding of truck trailing arm mounting brackets to prevent movement actually started with the recent race at Kansas Speedway and will continue through the All-Star Race and the remainder of the 2016 season, for that matter.
Two other changes come in the areas of electric fans and rear-wheel toe alignment. NASCAR is reducing the number of electric cooling fans, because the sanctioning body has come to the realization that more fans mean more downforce.
Also, the rule change regarding rear toe alignment will decrease the amount of skew, or slant, of the car. The decrease is expected to take away side force and make turning more difficult and reduce corner speeds by about 3 mph at CMS.
“Usually, the way a team would set that up is, on the right side, they take 0.6 degrees of toe out, and on the left side, they do about 0.3 degrees of toe in,” Stefanyshyn said. “We’re going to change the specifications, so it’s going to be neutral; it will be zero setup. That will take some of the skew out of the car, which will take some of the side force off the car.”
