CAGE RULES Check Box
- All competitor vehicles are required to meet the following cage rules, or have been evaluated to be equivalent by the Outlaw team. Vehicles that do not meet the following requirements will be evaluated individually, and all efforts will be made to work with the competitor to achieve a sufficient cage. Once approved (now, or in the past), the competitors vehicle will be allowed to compete in future Outlaw events provided that the primary 6 point cage structure is not modified, excessive damage requiring rebuild of more than 50% of the primary 6 or 4 point structure occurs, or change in ownership of the vehicle. If any of these situations occur, the vehicle will be require to be re-approved. Competitor’s vehicles that have been previously approved in all past events will be considered to have the primary 6 or 4 point cage structure approved, but will still be required to be inspected at the time of the event to verify vehicle soundness.
- The following requirements are based off the cage materials being structural ERW grades of steel as a minimum. Stronger material grades are recommended for unlimited classes, and if used can lessen the cage requirements. Contact with the Outlaw team is required for approval of any such substitutions. Recommended Dom tubing, chromoly tubing
- Competing vehicles that consist of a full OEM cab (including front & rear glass) that have not been gutted will be allowed to follow to lesser standards for the cage requirements.
