    We will abide by the Silverback Off-road Speedway rules for safety; each racer must wear a helmet, long pants, and closed toe shoes. 

    Each machine participating must have a number plate. If you do not have a number plate(s) on the day of the event, they will be available to you at the track for qualifying and on race day. For the Modified Class you will need to list "M" along with your number of choice. 

    We will have a tech inspection prior to qualifying on Saturday. The top three podium finishers of each class with also be subject to this same peer tech inspection after racing on Sunday. As a fellow racer, whether that be in your class or another class while spectating if you see something not compliant with the Class Rules, you must communicate this with one of the officials. If a machine does not pass the inspection prior to qualifying you will have until the end of day Saturday to address the changes. The machine must pass tech inspection prior to Sunday Race Day or you will be disqualified from competition. 

    • As noted above, a tech inspection will be held after the competition for the top three finishers of each class. If a machine is found non-compliant after competition their finishing position will be forfeited. This means the next best finisher will also be subject to the same post-race inspection. 
    • If more than one top three finishers are disqualified from competition, we will review the bracket and the next finishing position tie-breaker will be determined by your qualifying time. 
    • If any mechanical issues arise during Saturday's qualifying, your placement will be determined by any documented qualifying pass made. If the machine does not make a qualifying pass, the race day bracket will be built as your machine as the bottom qualifier. 
    • No open access to fluids in driver’s compartment is permitted - covers are required
    • Must have a Full Firewall: OEM or Modified/Aftermarket Firewall that covers to OEM specifications required
