Carl, I thought about competing too. But here are some of the rules that would have made me change alot of things and will impact you too.
4.16: Roll bars/Cages
W.E.Rock considers the cage as the safety bars surrounding the driver. Cages must be designed
to protect the occupant in the event of a rollover.
The following are roll bar/cage guidelines for competition:
4.16.1:
Six (6) point mounting cages covering the driver are required.
4.16.2:
OEM bars are approved for a portion of the roll cage.
4.16.3:
Handles are required on the interior portion of the roll-cage or vehicle.
4.16.4:
Round steel tubing (D.O.M Preferred) 1.5†O.D with 0.120†wall is compulsory for the
basic roll cage. Aluminum and/or soft metals are not permitted. Roll bar construction must be
welded. A W.E.Rock official must approve roll cages made of other material or in other wall
thickness/diameters.
4.16.5:
Connection positions of the roll cage must tie in to the frame of the vehicle; Body mounts
are considered a tie in point.
4.16.6:
The front-most position must be no farther toward the rear of the vehicle than fifteen (15)
inches behind the throttle and brake pedals.
4.16.7:
The Cage must have a space no wider than 24†above the driver’s head, and at least 1
spreader bar between the front main bar and rear main bar are required unless the cage top is
24†wide or less.
4.16.8:
Gussets must be welded in the four corners of the “haloâ€. Gussets may be tubing or plate
steel.
4.16.9:
A minimum of.040 magnetic expanded or flat sheet metal, or 1/8†aluminum, must cover
the area immediately over the driver seat and be welded or bolted to the roll cage. Steel tubing
must surround the roof panel.
4.16.10:
W.E.Rock recommends a spreader bar to be mounted under the dash area to connect
the right and left “A†pillars.
4.16.11:
If doors are not ran, a bar running from the “B†pillar, at approximately shoulder height, to
the “A†pillar, at approximately shin height, must be ran. This can be a bolt in piece.
4.16.12:
A “periscope bar†(a bar sticking straight up from the roll cage) is not allowed.
***A cage height minimum of 3†of the from around the entire helmet of the
drivers will be the Mandatory set standard for the 2007 season***
4.17: Seating
The following are seating guidelines for competition:
4.17.1:
Adequately padded headrest or neck support acceptable to W.E.Rock official inspectors
is required.
4.17.2:
Factory seats must be fastened to the tub in the factory mounting points or to the roll
cage.
4.17.3:
Aftermarket seats must be attached to the roll cage.
4.17.4:
Mounting points must be in good condition without rust or corrosion.
4.17.5:
An approved four-point harness is mandatory and must be worn at all times while on an
obstacle.
So once you have your helmet on measure and see if you have the required 3" min.
