Until March 1, 2015, the existing body rules in the 2015 IRRA® rulebook will be used: Section E, Body rule 1a, as written in all IRRA® classes.
Effective March 1, 2015, at all IRRA® Premier Races and on September 1, 2015, in all regions using the IRRA® rule set, the following body rules will apply:
Section E, Rule 1a (all classes but Stock Car): Bodies must meet the following dimensions: .008" minimum thickness on the nose of the body without any tape and .007" minimum thickness on the sides of the body, which may be accomplished using tape that must cover the entire side from wheel well to wheel well (on F1 bodies, from the front axle opening to the rear of the body side).
Stock Car section E, Rule 1a: Bodies must meet the following dimensions: .012" minimum thickness on the hood without any tape and .010" minimum thickness on the sides of the body, which may be accomplished using tape that must cover the entire side from wheel well to wheel well.
Regions may elect to enforce this change sooner than September 1, 2015.
Based on manufacturer input regarding the molding process, the IRRA® BoD believes that this is fair to all involved and still prohibits bodies made from .007" thick plastic stock as well as poorly-molded bodies.
The illustrations below indicate the approximate locations where measurements are to be taken.
