2017 Rules Update
IRA, as well as all other major winged sanctions, will be following these 2 rule guidelines released by the World of Outlaws. The World of Outlaws have been working with us, and others, on these every step of the way...... and we agree with them on these two issues.
Attached are two new car spec rules we are implementing for 2017. One is the wheel cover rule that has been out for some time now and the other concerns the carbon fiber issue that we have recently discussed. Hopefully, neither of these rules will adversely effect your program. At this time I don't anticipate any additional car spec rule changes for 2017.
