NASCAR announced Tuesday new rules packages that are in effect game changers for several upcoming races on the NASCAR Sprint Cup schedule. After announcing several weeks ago that a new rules package will be used this weekend at Kentucky Speedway, new rules packages will now be used at Darlington Raceway in September, and both Indianapolis Motor Speedway later this month and Michigan International Speedway in August. Richmond, the race that will set the field for the 2015 Chase for the Sprint Cup, won’t have a new rules package but will have a new tire.
For Kentucky the new low downforce rules package mandate a spoiler height of 3.5 inches, down from 6 inches at other tracks this season. Also, front splitters will have 1.75 inches less overhang. The series will race on a tire with more grip than last year at the track located in Sparta Kentucky. The tire used wasn’t designed specifically for the Kentucky race, but more grip typically means more wear and time off throttle in corners.
The rules are intended to improve passing. MORE>>>
