2010 ARCA Flat Rock and Toledo Speedway Rule Changes

(Late Models revised 1-8-10)

TO ALL DIVISIONS: In 2010, we will put a major emphasis on decibel limits. The rule is the same, but it will be enforced. We have been lax with this program, but a major emphasis will be applied to this rule in 2010. You will have 1 week to fix your problem; if you are still loud, you will start scratch in all events. If you are still loud on your third time you are at the track, you will not be allowed to compete. THIS APPLIES TO ALL CARS IN ALL DIVISIONS AT BOTH TRACKS. This was a topic at the recent MSPA (Michigan Speedway Promoters Association) meeting.
