Thread: 35 Ford Roll Cage

Then you'll need crossmembers to attach the cages main mount points. All this is spelled out in the SFI specs, as mentioned...

Yup, first order of business should be to get the SFI book and read it cover to cover. Just google SFI Foundation.

That is what I was asking to begin with, I guess I just did not clarify very well what I was asking. I have the rule book and understand the concept of the cage, but this is my first attempt at putting a cage in a car without a structure under the floor to attach to or as in the case of my camaro, between the subframe connectors, additional plate welded to the floor, and the front down bars from the halo bar and the ones going through the firewall to the subframe, there was plenty of support to attach the cage to.

While the rule book does give some information & drawings the SFI book goes into much deeper detail in both written explanation & color coded drawings. It's well worth getting an SFI book. I would also contact the Chassis Tech in your area that will eventually be putting the sticker on your project. If you keep him in the loop he will answer specific questions as they arise. And, when the time comes to get it certified, you will have built it to his recommendations so there won't be any surprises.

Thanks for the help and guidance
