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.

WoO Craftsman Sprint Series 2017 Rules Bulletin #1

15.9 Wheels

D.) Wheel covers: it is highly recommended that wheel covers have a minimum of 5 mounting points. However, both 5 and 3 mounting point wheel covers will be allowed for competition under the following conditions: Beginning with the 2017 racing season wheel covers having a minimum of 5 attachment points may continue to use dzus fasteners. Said dzus fasteners must be made of steel only. Wheel covers having only 3 attachment points must be bolted-on at all 3 points utilizing a minimum 5/16”, flanged steel bolt and an approved fastening (nut assembly) system.

Approved fastening (nut assembly) systems: Keyser Manufacturing, part #100 7-101.

Optional fastening systems that are equal or superior to the above approved system will be readily approved at the sole discretion of WoO Technical Officials.

The above information is subject to change per World of Outlaws guidelines.
