do you guys know know of a company that makes either bolt in or weld in cages that are in spec

karl wasabi · 02-05-2009, 03:34 PM

Are you planning on going to a D1 qualifier? If so, a Cusco will work because the Japanese are awesome and don't care about bends in the cage.

If you want a Formula D or SCCA cage, I think KW cages are the legal thickness and amount of bends. Someone please correct me if I am wrong.

If you have to ask...

chris300zr · 02-05-2009, 03:51 PM

you dont need a cage for the qualifier at MW, but you will need one for the series. GL

Safety Cage Purpose
The purpose of the safety cage is to protect the occupants in case of a rollover or a collision. It
must be able to withstand the weight of the car landing on the roof. A cage with six mounting
points or more is required
Intent
Chassis stiffening is a side benefit of a good safety cage system, but it is not the intent of these
rules. The removal or redesign of the cage, whole or in part, to comply with these rules, does
not imply that penalties will not be issued for violating the intent of these rules
Installation
The cage may be removable or may be permanently welded, or any combination thereof,
providing that all aspects of the cage meet these rules.
Padding
All roll cage surfaces that may come in contact with the driver shall be padded with high-density
padding.
Bends
None of the tubing may show any signs of crimping or wall failure. All bends must be Mandrel
type. The center radius of the bends may not be less than three (3) times the outside diameter
of the roll cage tubing.
Main Hoop
The main roll cage hoop shall be as wide as the full width of the interior and must be as close to
the roof as possible. One continuous length of roll bar tubing shall be used as the main hoop.
The main hoop must consist of not more than four (4) bends maximum, totaling one hundred
eighty (180) degrees +/- ten (10) degrees.
Diagonal Brace
At least one (1) diagonal brace shall be used in the same plane as the main hoop. One end of
the diagonal brace shall attach to the corner, or horizontal part, of the main hoop above the
driver’s head, within twelve (12) inches of the driver’s-side corner. The other end of the diagonal
brace shall attach to the mounting plate (or to the main hoop as close to the mounting plate as
practically possible) diagonally opposed to the driver’s head (passenger floor).
Forward Hoops - Option 1
The forward hoops shall extend from the main hoop (in a forward direction) to the floor by
following the roof and the “A” pillar of the car. There shall be a bar connecting the two (2)
forward hoops at the top of the windshield mounted as close to the roof as possible. The
forward hoops shall incorporate no more than four bends each. Optionally a Halo Hoop (Option
2)” or Front Hoop (Option 3)” construction may also be acceptable.
Halo Hoop (Option 2)
A “halo bar” extends from the main hoop (in a forward direction) following the roof line to the
windshield then following along the top of the windshield, then following the roof line back to the
main hoop, thus creating a “halo” over the driver’s head. A “halo” bar shall be constructed of one
continuous piece of tubing. One (1) down tube following the “A” pillar must support the “halo” on
each side of the car. The down tubes shall incorporate no more than two (2) bends each.
Front Hoop (Option 3)
\A “front hoop” is a bar that extends up from the floor, then follows the “A” pillar up to the roof,
then follows the roof line across the top of the windshield, then back down the other “A” pillar,
and then terminates on the floor. There must be one (1) horizontal bar (following the roof line)
connecting the main hoop and the forward hoop on each side of the car. The front hoop shall
incorporate no more than four (4) bends.
Rear Brace
The main hoop must have two (2) brace extending to the rear. The brace shall be attached as
near as possible to the top of the main hoop, and no more than six (6) inches below the top.
Rear brace must not contain any bends
The main hoop brace may be mounted at the rear shock mounts or suspension pickup points.
They may go through any rear bulkheads provided the bulkhead is sealed around the cage
brace.
Door Bars / Side Impact Protection
Door bars on both driver and passenger side must be used. The driver’s door window glass,
window operating mechanism, armrest, map pockets, door panel, and inside door latch may be
removed. *This gutting of the door is only permitted if the roll cage incorporates at least two (2)
NASCAR style door bars that extend into the door or an X brace.
Mounting Points
The roll cage shall be mounted to the floor of the car in a minimum of six points. The cage shall
not go through the firewall. The seventh and eighth points must attach to the firewall or front
fender wells. All cage attachment points must be mounted to plates.
Mounting Plates
Each mounting plate shall be no greater than 100 square inches and no greater than 12 inches
or less than 2 inches on a side. Welded mounting plates shall be at least 0.080 inch thick.
Plates may extend onto vertical sections of the structure. Any mounting plate may be multiangled,
but shall not exceed 100 square inches total including vertical sections.
Mounting Plates – Bolt-In Cage
The attaching points of a bolt-in cage to the body must use reinforcing plates to sandwich the
body. At least three (3) bolts are required for each bolt-in plate and the plate must be at least
3/16 inch thick. All hardware must be SAE Grade 5 or better with 5/16” diameter minimum.
Tube / Mounting Plate Specifications
Any number of tubes may attach to a plate so long as they are touching each other at the plate.
There may be a small gap between tubes to allow welding 360 degrees around each tube.
Welds
All welding must be of the highest quality with full penetration and Arc welding should be used
whenever possible. The welder, using magnaflux, should inspect all welds for quality. All
attachment points must be welded 360 degrees around the tube.

Save your money and avoid cusco. Their cages are a joke. The huge S-bends in the a-pillar bars completely neagate the point of even having a-pillar bars, and their clevis style bolt thrus for tube attachments are questionable at best. Not to mention they have ZERO triangulation, and no harness bar. Basically they're a piece of collapsible scaffolding that you can crush you skull on seconds before it impales you.

First post and already talking like you know your shit.

A cusco cage WILL hold up in a rollover...

Baxter · 02-05-2009, 04:26 PM

regardless of the fact that it held up in that specific incident, you can't refute that their "cages" are a horrible design. It's not approved to be used by any sanctioned road racing body.

Honestly, it costs the companies a lot more money to have such-and-such cage legalized.

Then the cage would cost more money.

Just make a cage. It isn't that expensive.

Approval is free. All you have to do is build a cage according to the rule set, such as SCCA's GCR.

10-66kruk · 02-05-2009, 06:03 PM

personally i would say have a custom cage built. Yes they are more expensive but everycar is different and normally bolt in cages have lots of leiway. Custom cage will get you that baller "a game" fitment. It will also be built to your requirements and tolerances. I wouldnt have chimed in but work at a roll cage metal fab shop. Seeing how it is done and how well fitting a good cage is blows a bolt in out of the water.
Unique Fabrication
Yeah custom shit is more but with something like a cage you can't really put a price on safety.

240trainee · 02-05-2009, 06:40 PM

Yea, Cusco cages have proven to withstand rollovers.

However, by looking at it from an engineering standpoint, they leave a lot to be desired in a cage in terms of design and build.

Just decide what you want out of the shit, and go from there. Honestly, even though I have the facility and capability to build my own cage, if I could run Safety21 and Tandem, I would. But, for my plans for my car, they require a NASA approved cage.

and to echo what was said before, if you have to ask on a public forum........

All attachment points must be welded 360 degrees around the tube. http://www.d1gp.com/v2/docs/2009_D1USA_Rulebook.pdf LOOK UP PAGE 22 ~ 24 i mean dude... do some research... i found all these in less than 5 min...

Their cages are a joke. The huge S-bends in the a-pillar bars completely neagate the point of even having a-pillar bars, and their clevis style bolt thrus for tube attachments are questionable at best. Not to mention they have ZERO triangulation, and no harness bar. Basically they're a piece of collapsible scaffolding that you can crush you skull on seconds before it impales you.

Yes they are more expensive but everycar is different and normally bolt in cages have lots of leiway. Custom cage will get you that baller "a game" fitment. It will also be built to your requirements and tolerances. I wouldnt have chimed in but work at a roll cage metal fab shop. Seeing how it is done and how well fitting a good cage is blows a bolt in out of the water. Unique Fabrication Yeah custom shit is more but with something like a cage you can't really put a price on safety.

However, by looking at it from an engineering standpoint, they leave a lot to be desired in a cage in terms of design and build. Just decide what you want out of the shit, and go from there. Honestly, even though I have the facility and capability to build my own cage, if I could run Safety21 and Tandem, I would. But, for my plans for my car, they require a NASA approved cage. and to echo what was said before, if you have to ask on a public forum........ __________________ Team Pterodactyl SHARK ATTACK!!!

They have FIA cages, just so you know. Cages SHOULD be mostly for looks anyways. __________________ http://bhworld.wordpress.com/
