No AR aluminum. No PVC coated aluminum. No sheet aluminum. Aluminum should EASILY Bend with fingers.
No welding. No solid-form cars (melting metal, casting a body, press/stamping body form). 
No reinforcing of the body or the frame. Four point cages allowed. Positively no crawler cages.
No weight added to body
Major build point: no bodies wrapping tight around or under bumpers. No bracing / kickers.
No extreme body-lining. Body lines to replicate that of a real car are fine, side lines are fine to harden. But no stiffening lines the length of the hood, roof or trunk.
Hoods/Trunks can be folded back 3/4-in. Fenders can be folded back 3/4-in. 
Small bead rolls to reflect GM Wagon roof lines are permissable, but cannot be enhanced in any way
No full-wedge vehicles, front or rear
One rear, single-layer strap over the back window, two allowed over the front window.
Two single layer straps from bumper to hood is allowed.
Roof Signs will not be extreme, and should not act as protectors to prevent roll-overs or aid/assist in putting a car back on its wheels. Recommended single layer, vertical, 1 3/4 in tall, 2 inches long and not tee-pee'ed/triangulated.
KEY POINT: These cars should be hard, but should buckle/bend.
2.0.1 WAGONS
Wagon may be fully decked from the rear body mount bar to the rear tailgate.
The deck may attach at three spots to the mount bar, three at the rear and may be attached at the sides in two places.
The deck may fold up or down 3/4-inch and attach to single-layered body panel
Decks will not be doubled over in any location or at any bends
Door bars and decking will not be attached in any way
Rear pillars go to the body, not the deck.
Wagons can not be sedagoned.
2.0.2 TRUCKS
Trucks will look like trucks with a hood, cab and bed.
Trucks may be fully decked from the rear of the cab rear tailgate.
The deck may attach at three spots to the cab and three at the rear bed/tailgate
Decks may be doubled over 3/4-inch
They may be attached at the sides in up to five more places either top or bottom.
Door bars and decking will not be attached in any way
2.0.3 CORE SUPPORTS and TAIL PANELS / TAILGATES
Core supports/Tailgate/Taillight areas will be vertical at 90-degrees, or close to it as possible, when cars take to the track, regardless of number of runs.
The core and tail panels will be single layer and not doubled over
The panels will turn close to 90-degrees forward or backward over the hood or trunk lid area.
The panel can tie in at the bottom of the fender or quarter panel, and fastener can pass through up to three other layers of metal ( for example: a folded over hood and an overlapped corner of the core, a flat fender, hood and overlapped core corner... NOT an overlapped corner of the core, folded over hood and folded over fender)
The panel should be held in place by no more than eight total fasteners across the top to the hood, bottom and sides of the fenders.
No wedging noses.
2.1 FASTENERS:
Fasteners should not be used to excess; be prepared to remove or drill out items.
Fasteners for bodies should not pass through more than four layers of metal at a time (folded hood to folded quarter; folded hood and core support where it's overlapped; hood through fender and core support). Note additional details regarding core supports (2.0.3) and cages (2.3).
General guides: 
Up to five to hold hood/trunk to quarters per side. These can be either on top or the side, not both.
The fasteners should not pass through the cage if they hold the fender/hood.
Five per side to hold cage in doors
Up to five to hold each bumper on.
Note additional details regarding core supports (2.0.3) and cages (2.3)
Thin beading wire - not mechanic or actual nine-wire - is allowed with no more than three loops passing through any opening.
2.2 BUMPERS:
Homemade front / rear bumpers outside the body/mounted to the body are acceptable.
Fasteners should not pass through more than four layers of metal at a time on a bumper.
Bumpers can be two-piece formation
Bumpers can be connected to the body with up to five fasteners going through no more than 3 layers of metal
Bumpers will be no more than 1/2-in deep at the greatest width;
Bumpers will be open on the ends
Two single-layer straps, pulling from a point on the bumper with the fastener passing through no more than three layers of metal, can reach up to the hood OR core support and pass through no more than two layers of metal behind the top fold-back of the hood or core support. Same applies to rear bumpers
No rear chassis bumpers on the chassis of the slash, front bumper should be either factory slash or RPM.
No nitro/foam bumpers.
Aftermarket plastic bumpers that occupy a large portion of the core support are not allowed.
The body should only attach to the chassis bumper via the skid plate if used. If there is no skid plate, the core does not get to attach to the chassis bumper.
2.3 CAGES:
Maximum thicknesses three-layers of metal/tripled for cage, and 3/4-inches wide.
No extruded material.
Cage bars may be folded and turned to an angle 3/4-in wide and 3/4-in tall.
Cage bars can connect, allowing the only instances of six-layer overlap. This area cannot connect to the body from the top or side, so the six-layer overlap will be free-floating.
The cage should connect to the body with the fastener passing through no more than four layers of metal.
Body mount bars can be held to the body through the hood and trunk, with up to three fasteners passing through no more than four layers of metal total (single layer hood, tripled bar).
It should not connect through a fold-over if the bar is tripled; if bar is doubled, then the four-layer rule is intact and allowed.
Window bars should be a single-layer of metal, with fasteners passing through two layers of metal total.
Door bars should not extend forward into hood and fenders beyond the body mount points, nor extend backward into the quarter panel/trunk area past the body posts.
Diagonal cage struts from body mount bar to door bar should be held with fasteners passing through no more than six layers of metal, not connecting to the body and not extending past the body mounts.
Braced cars/kicker'ed cars will not run.
2.3.1 HALO BARS
Halo bars may not extend down farther than the door bars.
Halo bars can attach to the door bars and fasteners can pass through six layers of metal.
Halo down-tubes cannot be held by fasteners attaching through the body AND door bar if exceeding six layers of metal (triple layer halo, triple layer bar and single layer door is 7 layers and not allowed; however halo support overlap between the door bar, between the bar and cage is allowed if floating/loose).
Halow down bars cannot connect to the bottom of a door panel that has been folded over from the bottom
Halo bars can be two-piece construction like bumpers
Halo bars will be open or open-ended like bumpers
Halos will be no more than 1/2-in wide like bumpers
Halo bars fasteners should attach to the roof in up to four places, doors in up to four, and cage bars in up to four total (divided per side)
2.3.2 WIRE ON CAGES
To help lower body heights, you may use wire to wrap through the hood or trunk and around body mount (dash, trunk) BAR, and it must be OUTSIDE the area of the body mount itself. It cannot wrap through/around or attach in any way to the chassis.
This also applies to repairs of broken bars, but can not serve as the body mount.
2.4 ATTACHING BODIES:
Body will be held on in four OEM locations only, and by pinned OEM or screw-on mounts.
May mount through body or through cage bars.
A fifth attachement point is allowed in the form of a skidplate (2.5 x 3 inches), and may be secured to the front of the chassis by a single (1) self-tapping screw. The plate should attach to the aluminum body with 2 rivets or screws and should attach to a single-layered core support. It should not loop through the existing chassis front bumpers.
No rear skid plates.
A body must remain connected by at least two OEM mounts. If a body is totally removed from the chassis or being held by only one, the car is disqualified. If a body is attached by only two mounts, judges have the discretion to remove the car (the added weight dragging around can cause excess heat, and a fire hazard).
2.5 PATCHING:
Bodies can be patched in up to four spots, with a patches measuring no larger than four-square inches (1x3, 2x2), doubled and attached to the body in four spots.
The body cannot be patched until metal is ripping.
Patches can be manipulated to match body lines.
2.6 DECKING:
No full decking/shoeboxing. Cockpit area should be open on all cars. Come prepared to cut these areas out. When you look through a car window, you see to the floor area - when you look through the windows of the RC car, you should see the plastic chassis.
It is expected all RC cars have window openings on all sides as a vehicle would.
3.0 ELECTRONICS (Batteries, Motors): 
Any single 2s battery with a maximum of 6000 MAH (stock style rules) 7800 MAH (National). Battery must fit in OEM tray (6.25 in long, 1 in tall, 1.75 in wide). No double battery setups.
