Driver Cage

• A roll bar or halo must be installed behind the driver seat, extending to or above the roof line, with round, square, or rectangular tubing, minimum 3″ to a maximum of 8″. Roll bar or halo may not be welded to the body in any way. Smaller proper tubing (DOM, roll cage material) may be used at judges' discretion.
• The roll bar or halo can be directly welded to the top of the frame rails or mounted to the floor with a maximum 12″×12″×3/8″ steel plate, welded or bolted. Only two vertical bars are allowed. The roll bar or halo needs to support the weight of the vehicle in case of a rollover.
• A horizontal seat bar may be welded between the vertical halo bars or between the door posts at seat back height, and another horizontal bar may be installed 6″ above floor height behind the driver seat, or bars may be welded in an "X" behind the seat between the halo bars. These bars may not be welded to the frame or body. It is recommended to secure safety belts to the cage if using aftermarket belts.
• A dash bar is to be installed between the lower area of the "A" pillar to replace the original dash. Two vertical bars can be installed from the dash bar to the top of the frame on the inside of the front door seam, welded to the top of the frame or attached to the floor with 12″×12″×3/8″ steel plate. All tubing must be 4″ maximum. Dash bar can be made of 6″×6″ angle iron.

• Frame kicker support bars from the vertical dash bars to the front frame area are allowed, not to exceed 12″ past the front of the firewall.
• A support frame for the fuel cell will be allowed, welded to the halo and seat bars. The fuel cell support frame may not be welded or attached to the frame or body in any way.

Bumpers

• Front or rear bumpers may use any factory inner and outer automobile bumper, or 5″×5″ 3/16″ square tube with open ends and nothing inside.
• Bumpers can be no wider than tires, front and back.
• Bumpers may be mounted with any automobile bumper bracket and shock mounted on one side of the frame, extending no farther back than the first 12″ of frame. Pick one mounting method only.

• Front bumpers can have two straps 2″×½″ thick welded 6″ on bumper and 6″ on radiator support. Bumper brackets must be touching the bumper.

Trunks & Hoods

• You can fold hoods or trunk lids over. Do not slide your hood or trunk forward or back — trunk must remain on hinges.
• Your trunk lid may be V'd in the center but must remain at least 8″ off the trunk floor (measured from the top of the frame rails, not the spare tire hole). If tucked to the trunk floor, only 12″ from the end of the trunk cavity, 24″ total, in a 6″-on/6″-off welding pattern.
• Trunk lids must have a 12-inch hole cut in the center for inspection purposes; the hole may have 3 bolts (3/8″ or less) and 1.25″ diameter washers bolting the layers together.
• 2 – 1″ all-thread may go from the trunk lid to the frame or trunk pan vertically; if it passes through a body mount hole, you must have a 1″ spacer between body and frame.
• Trunk tie-down plates, sheet metal to sheet metal only, maximum 4″×4″-¼″ square. No plates welded to frame.
• Hoods must have at least a 12-inch square hole over the air cleaner cut out in case of fire. Holes may be bolted back together with 3/8″ or less bolts and 1.25″ washers, no more than 12 bolts total. Up to four 1″ all-thread with 4″×4″ washers may hold the hood down. All hood bolts must be placed outside the windshield bars and be vertical. No welding of hood to bumper. Hood MUST be opened for inspection or have a large enough cut-out to see the engine fully.
• Trunk lids may be chained, wired, welded, or bolted from sheet metal to sheet metal. No welding trunk to bumper. All doors and trunk can use 3″×1/8″ strapping or ¼″ rod for filler to weld seams.

Suspension

• Suspension must be stock height. Bumper height not to exceed 24″ to the bottom of the bumper, and must be a minimum of 14″ from the ground to the bottom of bumper or frame, front and back.
• Leaf springs must be stock, made of stock spring material, minimum 1″ stagger. Maximum 8 leaf springs per side, no thicker than 3/8″, no wider than 2¾″. Main leaf must be the top spring in the pack, going down from longest to shortest. Springs may be re-clamped, 4 clamps per side; homemade clamps can't exceed 2×4×¼″.
• Coil springs can be changed to a stiffer spring or add a spring. You may run up to a 1″ bolt from your rear end housing to the package tray — no chains allowed. You can either bolt or chain your rear end in, DO NOT do both.
• You cannot change the length of trailing arms to shorten or extend them. Rear control arms must be stock but can be reinforced/welded solid.
• Do not raise the suspension any other way except what is listed above.
• You can bolt, wire, or chain coil springs to rear end and frame to prevent springs from falling out — do not go through the body.
• You may weld leaf spring mounting brackets to prevent them from becoming unbolted. You can loop chain or wire (1 loop of 3/8″ chain or 4 loops of #9 wire) from rear end to frame in 2 spots per side, around the frame — do not bolt the chain to the frame. One link only may be welded to the side of the frame if you choose to weld the chain instead of wrapping it.
• When attaching leaf spring brackets, 4×4″ ¼″ square tubing no longer than 4″ may be welded to each side of the frame rail. Do not reinforce factory mounting plates.

It is highly recommended to reinforce the driver's door with a minimum of 1/8″ plate, not exceeding 6″ past each driver's door seam — plating the whole door is strongly suggested. All other doors and trunk may be fully welded with 3″×1/8″ strapping or ¼″ rod for filler.
• Firewall forward, you may also weld two ¼″ solid beads on frame seams only, over existing manufacturer welds. Must leave one frame hole open for inspection in front of the firewall on each rail.
• Frame patching: ALL frame patches will be painted WHITE and have a ½″ hole drilled to determine thickness, ¼″ maximum thickness — must be done or you will not pass inspection. Allowed 12″ firewall forward, 6″ behind front door seam, 12″ hump plates. Patches behind the firewall mounted on the outside of the frame only. No patches can exceed the width of the frame. Fresh or pre-ran cars can have patches.
• Body mounts: bolts and spacers can be replaced or discarded — no bolts larger than 5/8″ with washers no larger than 3″.
• Rust repair/patching: you can patch rust holes in sheet metal with sheet metal only. Do not cut rust out; weld 2″ beyond rust. Passenger side patches maximum 4″×4″, maximum 18-gauge metal; patches not allowed to touch each other to fill a hole.
