All belts and harnesses must be secured to the framework of the car, have
frequent inspections and be kept in sound condition at all times.
All belts shall be of the quick release type, no thread through type belts will be
permitted.
Installation per manufacturer’s specifications and 5 point harness not more than 3
years old.
Driver suits are mandatory. Double layer HIGHLY RECOMMENDED.
Driver gloves & shoes are HIGHLY RECOMMENDED.
Drivers must wear a helmet carrying at least a valid SA 2000 standard SNELL at
ALL times on the race track including but not limited to track packing, warm ups,
and competitive events.
Any modification to the helmet, for any purpose, should not detract from its
effectiveness.
A master kill switch shall be placed on the rear speaker deck of all 4 cylinder race
cars.
This kill switch must have a bright circle or contrasting color around it for easy
access and recognition for the emergency personnel.
All crews must carry an operable fire extinguisher of 20 pounds marked with the
car number in 2 inch numbers/letters in the rear of their transporter, capable of
extinguishing gas and oil fires.
The mounts must be run at the same direction, as the belts are intended to secure
the driver.
The belt webbing must be protected from any sharp cutouts in the sheet metal or
any other sharp edges.
Seat belt webbing that comes into contact with any sharp or unradiused metal
edge must be protected from that edge by means of push on grip vinyl trim.
The areas of concern are the webbing slots in the metal racing seats.
All the seat manufacturers either roll the edge or supply the seat with trim
protecting the webbing from abrasion or cutting under impact conditions.
Webbing entry slots into the seat with an existing metal roll of 1/8 inch smooth
radius will not require vinyl trim.
The areas where the webbing slot has been enlarged by filing or cutting are of
particular concern.
In most instances the edges have been left sharp, increasing the incidence of belt
failure.
As racing seat belts are subjected to severe conditions, it is encouraged that
worn/frayed belts are replaced immediately and undamaged belts are replaced
every 36 months.
The date sewn into the webbing should be used as a guide.
Where the seat belt date is known to be “new old stock”, it is acceptable practice
to extend the replacement date on that set of belts to 36 months from date of
manufacture.
Damaged belts will also not be permitted.
All belts shall be of the quick release type, no thread through type belts will be
permitted.
