Michigan International Speedway is getting ready to host the NASCAR Sprint Cup Series FireKeepers 400 on June 12. And, it should be no surprise that NASCAR continues to adjust its rules for the sake of better racing for the fans.

It was announced today that adjustments to the aerodynamics packages for the Sprint Cup cars will further reduce downforce and sideforce. Now, this has shown to create a better on-track result for spectators, though top speeds will be a bit lower than in years past. Instead of wide-open throttle racing, adjustments to the sideforce toes, splitters and spoilers will force drivers to let off of the throttle heading into the turns. Theoretically, this should result in a more competitive racing atmosphere where engineers expect there to be more passing opportunities during the 200 lap race.

The weekend racing schedule is as follows:

Friday, June 10 - ARCA Racing Series Corrigan Oil 200 and Sprint Cup Qualifying

Saturday, June 11 - NASCAR XFINITY Series Menards 250

Sunday, June 12 - NASCAR Sprint Cup FireKeepers 400
