All cars must have an SFI approved type five or six-point racing harness three inches (3”) wide that is equipped with a quick release buckle.

Be sure to regularly check your safety belts for damage such as fraying, tearing, etc.  If this should occur, the safety belts should be replaced immediately.  MSRS endorses the belt manufacturer’s recommendation that the belts be changed two (2) years after the date stamped on the SFI tag regardless of the number of times the car has been raced. The safety belts are like a helmet, in that they are designed for protection in only one major impact.  If you have had a significant incident, the manufacturer strongly recommends immediate replacement of the belts.  Also, make sure that your safety harness is totally secured and that you have pulled the straps as tight as possible anytime you drive the car.


On-board fire extinguisher is mandatory for your safety.  Fire extinguishers placed in the car must be in working order and cannot and will not be used for weight purposes and anyone found doing so will be penalized.

All drivers must wear an SFI approved neck collar anytime he/she is on the track.


These items are not required but are highly recommended.  An individual track or promoter may require some of these items.

  • Knee pads
  • Steering wheel pad
  • Arm restraints and helmet restraints on seat
  • Safety wire on body and other nuts and bolts throughout the car


All MSRS approved weighing, measuring and testing devices used by the MSRS officials are the standards for which will determine compliance with the rules and regulations.  A competitor’s equipment, gauge or instrument will have no bearing on the enforcement of these rules.

All plastic and fiberglass body components must be firmly attached to every MSRS car competing in any race.

Any MSRS car may be denied entry to start a race by a MSRS technical inspector if body components are not firmly attached.


The car must have numbers that are a minimum height of fourteen inches (14″) on both doors and on the roof (roof number facing towards the inside of the track).  The car number, minimum of three inches (3″) tall must be on either the right or left side of the front of the car.  If two drivers show up at the track with the same number, the number registered with MSRS will stand and the other participant must choose another number that is not taken.  The size, color and style of numbers must be adequate to permit prompt identification by track officials at all times.  Roof and door numbers must not slant more than thirty degrees (30°) from vertical.


No scoops or duct work will be allowed.  Fans may not be placed anywhere on the car.


All cars must have Lexan windshield, rear window, and quarter shields intact at all times.  A MSRS car will not be allowed to participate without the shields in place.



The Briggs and Stratton Vanguard 20HP engine is the only engine to be used.

If this rule book does not specifically say that you can change/modify/add something, then you must consider that the change/modification/addition is illegal.  Any questions about the legality of a change/modification/addition not covered in this rule book must be answered by MSRS in writing and presented to the tech inspector upon request.
