be relocated to the back seat area.
Every vehicle is required to have rollover protection of a minimal 2-point “halo
type” rollover bar. Rollover bar is recommended to remain inside the vehicle but
may be outside the vehicle if the driver prefers. This is for your protection, and
must be strong and attached well. If officials do not feel you have adequate
rollover protection you will not compete. This means if we can physically move
your bar by hand, you will not race. This is to keep you as safe as possible.
For driver and passenger protection if you are only running a “halo type” roll bar
and do not have a 4 point cage inside the vehicle you must have some form of door protection outside both doors that will be occupied, such as a grader blade
or “Channel” running from the front post to the center post of vehicle and bolted
securely. This is not to be used to strengthen the overall vehicle, only for the
safety of the vehicle occupants.
If your vehicle has a full roll cage or you are using a derby type cage, it must not
extend through the firewall in the front of drivers compartment or through the
backrest of the back seat area in the rear. Cages shall not be attached to the
frame only the body or floor pan as to not strengthen the vehicle. IF THE
CAGE/DOOR PROTECTION OR ROLL BAR IS DEEMED UNSAFE BY

All fuel tanks must be removed from underneath the vehicle and be placed inside
the vehicle. Fuel Cells are recommended but factory tanks will be allowed for
fuel-injected vehicles. Once the tank has been moved inside it must be protected,
strongly secured, and covered. Preferably all vehicles will have a frame
extending from the safety cage or “halo Bar” that the tank is attached to and
protected by as to not be knocked loose when the sheet metal of the floor pan
begins to bend. If you plan to compete in these types of events in the future, the
purchase of a high-pressure fuel pump and a fuel cell is strongly recommended
as it can be moved from vehicle to vehicle with ease.
IT IS STRONGLY RECOMMENDED THAT ALL VEHICLES HAVE A SMALL
FIRE EXTINGUISHER MOUNTED IN THE VEHICLE WITHIN REACH OF BOTH
DRIVER AND PASSENGER.
All vehicles must have working brakes.
If vehicle has a factory stock bumper that is plastic, you may replace it with any
OEM bumper; bumper may be seam welded and capped. No extremely pointy
bumpers will be allowed. OR you may use a homemade bumper (4x4x1⁄4 MAX).
Bumper should not extend farther than 8in past the outside of each frame rail.
ABSOLUTELY NO POINT on homemade bumpers. Please attach all bumpers
well by welding, chaining, or bolting to keep them from falling off during the
competition. This is to be done within reason only to keep bumpers attached.
Drivers will be allowed 2 pieces of strapping (4in MAX) from core support to
bumper and from deck lid to rear bumper. The strap should be on the outer edge
of the radiator hole. This is not to make the car stronger, and is only intended to
help keep bumpers attached. Do not push this rule or make a gray area from this.
It is very simple and to keep bumpers on these cars front and rear.

Hoods must be bolted, chained, or wired with a maximum of 8 places. All thread
