Grade 5 bolts on two weight clamps. Weights secured by one bolt

The use of at least a DIRT approved five point seat belt
system including a crotch belt is required. The system is to be
mounted to the frame and not to the floor pan. 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. The date on the belt must
not exceed 4 years.
b) 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.
c) 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 24 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. Belts older than 48 months will not be permitted for the 2006 season. Damaged belts will also not be permitted.
a) There must be no sharp or protruding edges in or around the cockpit, which would impede the driver’s rapid exit from the car.
b) A headrest (behind the head) with padding is required.
c) A right headnet in the absence of a padded right headrest is required. Headnets must be equipped with quick release mechanisms.
d) There must be a marked electrical kill switch in reach of driver.
e) There must be a marked fuel shut off valve in reach of driver.
f) All drivers must wear a clean one-piece DIRT approved driver’s suit, quilted or with underwear, head socks, gloves, foot socks and shoes to DIRT approved specifications.
g) An undamaged Snell SA95 or newer spec full face helmet is mandatory for all events including track packing.
h) 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.
i) Neck collars or similar restraints are suggested.
j) Arm restraints are suggested.
k) Flame retardant seat, roll bar, knee and steering pads or padding are required.
l) Driver’s suits, gloves, shoes and helmets must be presented at Tech inspection.
