BROOKLYN, Mich. (July 7, 2015) —NASCAR announced on Tuesday changes to the race package for the Pure Michigan 400 at Michigan International Speedway on Sunday, August 14.

The changes to the car for the race include a nine-inch spoiler with a one-inch wicker bill, a two-inch splitter and a 43-inch radiator pan. These changes are expected to increase the drag on the cars and optimize the racing. NASCAR spoke to the OEMs, owners, drivers and MIS about the package options to select the one to make the competition stronger.

“MIS is very enthusiastic and supportive of the new rules package announced today by NASCAR,” track president Roger Curtis said. “Since we repaved in 2012, not only has MIS been the fastest track in NASCAR, but our fans have seen some very competitive racing with several lead changes and winners such as Jeff Gordon, Dale Earnhardt Jr and Jimmie Johnson.

“We are excited at any steps NASCAR takes to make the competition even stronger and we loudly applaud their new willingness and commitment to make improvements for the fans during the season.

“Given the proximity to the start of The Chase, the Pure Michigan 400 would already be a race of high drama and excitement but we think with these new rules fans will be in for a fantastic race weekend full of emotion, speed and even better racing.”
