I did get 1, which is this one, and I do like the design of this, considering it ties the rear shock towers together, and this would be way better than a tower brace.

In other words, your roll cage bears no resemblance to mine other than the fact that it is made out of bent metal tubing.

Karack and I both posted links to pictures and diagrams. Unfortunately, it just isn't very common to have a roll cage with a full interior because both the safety and handling are better without the interior.

yep, probably not going to have many pictures of people with an actual cage and much of an interior.

sort of like putting a big turbo on your car and adding a 200lb stereo, in a sports car.

That would be weird, because you don't need 200 lbs to have a good sounding stereo, personally I just upgrade the stock parts to better components. Fortunately for me, my car is the non-powered type, so basically the base 5-lug version, so I have weight savings on having everything manual. Then I'll have more weight savings when I remove the stock catback and install the corksport catback that I have. A/C is already gone so even more weight gone. So honestly, I don't think weight is going to be too much of a problem.

Interesting...
I think I remember reading that the power windows actually weigh less than manual. its only a catback, not due how much weight that will really save. A cage will add more weight than u save from the exhaust, but being a base w/o amenities u should be@ about avg weight for an fc +/-

That's hot.

How does your door looks like due the side bars?

heres mine, its a cusco 4 point bolt in.

As is standard with the NASCAR style side bars, the inside panel of the door is cut out. An aluminum panel is then put in place to satisfy safety rules.

If the bars do not bow out like you see in the picture of my car, then they do not offer as much protection and there is not much space for the driver.

In the case of my car, I still have the windows that can be pulled up and down, but no cranks. I am not sure if this is legal for racing or not, but I have yet to put my car back on the track so it doesn't matter right now.

Cool.

At the moment i am thinking about something like rxspeed7 posted for the future but with somekind of harness bar at the back.

But that rollbar goes all the way to the floor right? Don't you get problems with the seat?

Oh wow, that's pretty cool, actually has a full interior with a cage.

FCs4226

how much for a cusco bolt on style?

gawdodirt

If it was properly fit, not much comprmise. However, it would have to be a modified mail order one or a custom.

I'e seen and fabbed a few complete cages in trucks and cars taht maintained the full interior. Even seen a very few that once they were installed, the inerior was instlled OVER the cage so you couldn't even see the cage. Very work and precision intensive and costly to have it done.

To address your question. You won't have to lose much if any interior.

Well atleast we know if you roll over your passenger will be safer than you

fully welded into roll bar.


with nearly full interior (just missing the passenger side cargo bin (battery box is too tall)

Ah, there we go, that's what I was talking about with the carpet on the rear strut towers and the dash cut away by the defroster vents. I have seen a few cars like that.

Notice how the seat back rests against the horizontal bar for better support. This was originally required in SCCA, but most of the composite seats were designed to have some flexing space. If you have metal seats, then you definitely want to do this. Also notice how the harness is attached to the bar rather than the floor. The SCCA diagrams show how to safely mount the harness like this.

There should also be a bar running under the dash, but you can't really see it in those pictures. You can see it better in the first picture that I posted of my cage.

The angled bar adds strength to the main hoop, and also to the whole cage structure. Sure, it would probably be better if mounted the other way, so I assume that is a J-Spec RHD design mounted in a LHD car.

A little bit of overkill on the trunk mounting, but I bet you have a nice solid place to mount the fuel cell straps.

How much weight does that add? Just curious.

Syritis

yeah i figure the last thing i want during a roll cage is for the cage to poke through and puncture my gas tank.

I weighed it at the time but i forget the number, i'm gunna estimate from what remember, (i installed it as one piece) probably 100lbs.

car weighs 2800lbs with me and fluids. no spare tire, no stereo, no heater, no blower. steel hood.


I figure i did pretty good job with it for using a drill press, grinder and a 110volt welder.
