I was asked politely for some pictures of my roll cage so I figured that it would be nice to post them for everyone to see. They're just in the order that I took them and if I get the inkling, I'll reorganize them so that they're grouped together based on what part of the car they're on.
My car was built in 1998 by Ken Kovach and has been grandfathered into the current regulations. The current regulations require compliance with FIA Appendix J Article 253 but allow a material substitution of DOM (Drawn Over Mandrel) steel in place of CDS (Cold Drawn Steel) since DOM is easier to come by and has comparable properties to CDS.
A lot of people get excited about using Chrome-Moly steel but the truth is that it doesn't matter as long as the cage is made from steel and the welds are good. I could talk for hours about different material benefits but I won't unless someone wants to know.
Per the current FIA regulations, my cage would need a bar going from the top corner of the windshield down to this location. You're allowed to cheat it out a little so you have some clearance for the steering wheel but other wise it needs to be straight.
A very appropriate bumper sticker considering what this car has been through.
It looks like a jungle gym in there so I took a couple of close ups of the different intersections. We're required to carry 3 of those DOT triangles and one of them has to be within reach of the driver or co-driver. The third one that I carry is usually strapped to the door bars on the passenger side and then pinched between the door and the cage.
This is where the main hoop meets the floor on the driver's side. The shot is looking forward. With how many bars come together at this point, it is a very stiff part of the car.
I'm not really sure why this bar was tied in right here.
The top part of the main hoop and the intercom strapped to it. The car is extremely loud on the inside when you're on stage. It's not so bad when you're transiting on pavement and not driving balls to the wall. We'll just say that I'm glad my new helmet has built in hearing protection.
This is a decent picture to indicate how the front of the cage was constructed. This cage uses a halo design where there is a continuous bar that goes along the top of the car (like a halo) and ties into the main hoop. This design is no longer allowed but I'm allowed to continue to use it because my car was built and logbooked before the rule went into effect. This is also the location that the extra A Pillar reinforcement needs to tie into on the top.
The seats have to be hard mounted to the floor.
I need to get this car back in the garage before it rusts apart.
Some body damage. You can also see the fuel cell protection which is required.
