    18.3 OTHER

      A. Due to the inherent creative nature of this category of classed and the resulting member questions about the intent and interpretation of the rules, the SEB will issue clarifying Tech Bulletins in SportsCar magazine on an as-needed basis. Car contructors are cautioned against overly creative or tortured interpretations of these rules. When in question, contact the SCCA National Office for clarification.
