This weekend the Sprint Cup Series goes to Michigan for its 15th race on the schedule and once again they'll be racing with a new aero package this weekend at the two-mile speedway. Last season fans didn't care for the high drag package that NASCAR implanted on teams at the track, but this season many drivers and crew chiefs feel that the racing will be better with the lower down force package.
NASCAR will make changes to the rear spoiler, front splitter and rear deck fin for two upcoming races to see how it plays out with the first being at Michigan this weekend. It is a proposal to continue to lower the aerodynamic downforce and the sideforce in an effort to make the competition closer the intermediate race tracks. The changes are similar to what the teams ran at Charlotte in the Sprint All-Star race.
Michigan has had some snoozefest races in the past few years and NASCAR is hoping that this weekend the package will make the racing much more competitive. Last season, Trevor Bayne finished 9th in the rain shortened event at the track. The race only had 17 lead changes throughout the event in 2015.
The changes for this weekend's race consist of of a reduction in spoiler height from 3.5 inches to 2.5 inches, a splitter reduction of two inches and a re-sizing of the rear deck fin to complement the spoiler change.
