Minimum Driving Gear
A jacket or driving suit
designed for kart racing. If the driver chooses to wear a jacket, full
length heavy weight trousers are required.
A full face, solid shell
(no flip up type) Snell 2005 approved or newer helmet equipped with a
flip up type face shield.
Drivers must wear shoes
that completely cover his/her feet.
Drivers must wear gloves.
Drivers must wear a neck
collar/helmet support designed for kart and/or auto racing.
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.
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.
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
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:
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.
brake rotors must be made from steel or cast iron and be THICKER than
1/8” and have some sort of venting.
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
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.
Braided steel re-enforced
brake lines are recommended, but not mandatory.
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.
Body Work and Dimensions
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.
Body work approved in WKA,
IKF CIK is acceptable in the UAS as well.
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.
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.
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.
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
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.
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.
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;
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.
If it desired to use some
new sort of unmentioned material, please contact your Regional
Administrator for consideration.
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
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.
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.
Wheels. Maximum wheel rim
diameter is 6”. There is no limit to rim width.
