International Stunts Master, often referred to as ISM, is a special competition managed by Mark L. Rivers since 2006, usually held between consecutive months of December and January. Conceived as a sort of "World Cup" for Stunts, it pitches selected top racers in a variety of tracks and cars on a short contest that lasts for about one month and a half. Invitation criteria for the first two editions were based on SWR rankings. The editions of 2009 and 2010 saw the inception of a qualifying round open to all racers - the fastest 80% of the involved racers achieving qualification to the final stage. For 2011 ISM followed a streamlined formula, doing away with the qualifying round (entry was granted to ZakStunts 2010 podiumers in addition to a few special invitees) and holding all races on a single track, with different cars.
