COMPETITION MODIFIED CLASS

These vehicles are designed and built primarily for competition. They are not required to be “Street Legal” and are normally towed or trailered to the competition site.  Engines, running gear and bodies may be modified to gain maximum advantage in competition events. Any “Street Legal” vehicles that have equipment exceeding its class will be placed in this class. Brackets are separated by actual weight by cubic inch displacement.
