4. Safety Guidelines


  1. Minimum Driving Gear

    1. A jacket or driving suit designed for kart racing. If the driver chooses to wear a jacket, full length heavy weight trousers are required.

    2. A full face, solid shell (no flip up type) Snell 2005 approved or newer helmet equipped with a flip up type face shield.

    3. Drivers must wear shoes that completely cover his/her feet.

    4. Drivers must wear gloves.

    5. Drivers must wear a neck collar/helmet support designed for kart and/or auto racing.

  1. Karts

This program is intended for vehicles classified as Go-Karts. The Go- Karts are to be constructed in a safe manner. Maximum overall dimensions will be determined by the least restrictive parameters for any division as generally set forth by IKF, WKA, KART and CIK.

    1. CHASSIS are to be constructed from steel tubing that is suitable for safe operation in high horsepower competition applications. Karts are to be what is commonly known as 'Flat-Karts' meaning that they are not to have roll cages or bars positioned over the head of the driver. Chassis are to be solid,meaning that they are not to be equipped with leaf or coil springs and any type of shock absorbing device that acts as an active suspension device. Particular attention is to be made to the integrity of joints and welds.

    2. STEERING. All fasteners used in the steering system must have some sort of device to prevent them from coming loose. Such devices may include , but are not limited to, cotter keys (pins), safety wire, double nut and/or snap ring or clip. A single lock nut or a nut with lock washers is not acceptable by itself.

    3. Brake System. In general, the brake system utilized on a UAS kart must compliment the engine(s) that are used on the kart. It must be capable of locking the rear axle in the event the throttle was to stick open. The brake requirements will vary depending on the power source. All UAS karts MUST meet the following minimum criteria:

      1. Under no circumstances are stock 'Mini Lite' type brakes to be used. The calipers may be used on single cylinder karts with a suitable upgraded rotor.

      2. All brake rotors must be made from steel or cast iron and be THICKER than 1/8” and have some sort of venting.

      3. Karts that are required to weight 410 lbs or more must have an internally vented brake rotor, or a dual rotor/caliper system. Thin slotted or drilled rotors are not considered vented.

      4. A steel plate, at least 3/32” thick must be placed between the brake rotor and seat to prevent the brake rotor from cutting through the seat in the event that the seat was to come loose.

      5. Braided steel re-enforced brake lines are recommended, but not mandatory.

      6. All fasteners used in the brake system must have some sort of device to prevent them from coming loose. Such devices may include , but are not limited to, cotter keys (pins), safety wire, double nut and/or snap ring or clip. A single lock nut or a nut with lock washers is not acceptable by itself.

    4. Body Work and Dimensions

      1. These body work rules are here to provide guidelines for acceptable safe body work. It is not the intention of these rules to limit performance or invention in any way. They are written in the spirit of allowing as much flexibility and creativity as possible but with safety in mind. The overlying question to answer when examining body work, is it safe.

      2. Body work approved in WKA, IKF CIK is acceptable in the UAS as well.

      3. In instances where karts do not have body pieces, adequate bumpers and nerf bars must be installed that meet the same criteria as body pieces.

      4. Body work is to be no higher than 30” from the ground measured at the center of the rear axle. It may extend back as far as the rear bumper at that height. Extended rear bumpers are permissible. Forward of that point, the side panels are to angle downward to a point that intersects, no higher than 15 inches above the ground at the center line of the front axle spuds. If a nose is to be used, it is to be no more than 15” above the ground measured at the center of the axle spuds of the front spindles. This only applies to the vertical external side panels.

      5. External body skin or vertical side panels must be made from plastic or a composite material. Lexan may be used in a wedge body design in conjunction with a standard kart side panel or other acceptable side panel material as long as the Lexan is attached at least 4” above the bottom of the standard kart side panel. Sharp edges are not permitted regardless of what material is used for body work.

      6. Nose pieces, front wings, fairings are to be designed in such a way that they do not block the drivers vision or trap the driver in the kart in case of a mishap, create a hazard for other drivers and must provide adequate foot protection.

      7. Front end components are to be made in such a way that they cannot become a wedge that could lift a kart in front of it off of the ground in the event of contact.

      8. Support posts, spars, braces, etc. are not to be made and attached in such a way that they cannot puncture a driver in the case of an impact with another kart.

      9. Guidelines for body panels that are located inside of the vertical side panels:

          The interior body panel/wing can be made from a variety of materials;

        1. Fiberglass

        2. Plastic composites

          • When using plastic composites, the racer/builder will take into consideration the melting point of the material and insure that there is a safe distance between the interior panel and any part of the engine or exhaust system.

        3. Sheet metal

          • When using sheet metal for interior panel, all edges must have a minimum of a 1/4” double hem. There are to be no sharp edges exposed.

          • On radius areas, where a hem is not practical, there must be a plastic or rubber capping material over the edge that will extend no less than 1/2” into the material on both the top and bottom.

          • The capping material will be secured a maximum of every 5” to the sheet metal by drilling thru both the capping material and the sheet metal and affixing with some form of fastener. Glue or other adhesives alone, used to apply the capping material, WILL NOT be accepted.

        4. If it desired to use some new sort of unmentioned material, please contact your Regional Administrator for consideration.

        5. Materials that are known to shatter and/or shard will not be permitted for this application.

    The race track promoter has the final say regarding the body work that they permit on their race track.

    1. Chain Guards. All karts that have inboard drive are to be equipped with an adequate guard that protects the drivers arm in the event that the kart breaks or throws the drive chain or other drive train component failure.

    2. Ballast Weight. All weights must be fastened with an adequate size grade 5 or better bolt with a nut and a cotter pin or double nut. A single lock nut is NOT acceptable. Weights bolted to composite or plastic seats must have large OD fender style washers to prevent the bolt from pulling through the fiberglass. Weights are NOT to be bolted to body panels.

    3. Wheels. Maximum wheel rim diameter is 6”. There is no limit to rim width.
