The World Stunts Championship (WSC for short) is a Strict OWOOT, Argentina-based international competition started and managed by Paleke from 2004 on. As of the beginning of 2008 it was the sole active strict OWOOT contest; however it entered indefinite hiatus halfway through that year's season.
The only car allowed for all races in WSC was Porsche March Indy. Yet, it was permitted to use either Stunts 1.0 or Brøderbund 1.1. A few rules were less than strict in the tournament. For example, driving on top of a tunnel was OK. In version 1.0, the top of the tunnel is passable, so crashing against it was impossible, thus, it makes sense to allow this for version 1.1. Skipping a slalom was allowed as long as the car remained OWOOT at all times. Whether going directly through slaloms was accepted should be researched by watching the replays (to be done).
At a point (probably about the second half of 2006), a track design contest was held. Each racer could post up to two tracks. Later, all racers would vote for their two favourite tracks that weren't their own and the (about four) tracks with the most votes would be used for racing the following months.
