Mojave Magnum #5 requirements on Oct 8, 2016 (185995) | MotorsportReg.com

Entry is limited to 125 total participants (persons, not vehicles!) each day, with an included cap of 40 "one-day" participants on each day.  Open to both cars and motorcycles. Open only to licensed drivers/riders 18 years of age or older (sorry, we cannot allow minor drivers or riders).  Motorcycle riders must have a motorcycle endorsement on their driver's license. Graduated speed limits apply to each entry, based on safety equipment, tire ratings, and prior racing experience.  Basic safety equipment (belts, helmet, proper clothing, etc.) is required.  3-point OEM-type seat belts are the minimum for cars. For cars, speeds above 180 MPH require the driver to wear a racing firesuit, racing gloves/socks/shoes and a racing helmet, and the car must have racing harnesses and a roll bar unless exempt.  All motorcycle riders must wear a minimum of full leathers/boots/gloves and a full face helmet with face shield. Helmets that are only rated DOT, with no other rating, are not allowed. Snell-rated helmets older than SA2005 and M2005 are not allowed. Snell K (kart) helmets not allowed.  All vehicles must meet our safety standards and be in good condition. Tires must be at least "S" speed rated (hopefully much higher, because your speed limit depends on it!) and manufactured in 2010 or later (i.e., the 4-digit sidewall date code must end in 10 or higher).  Other restrictions may apply.  See the FAQ, Car and Bike Preparation Guides, and Rule Book on our web site for details.
