Ultimate roll cage thread

[jhelgesen]

I'm on the fence for either buying or building a cage for my 911. Car is track only at this point, probably going to pca and nasa events.

Buying is semi quick. Design and build my own is a good project, I have time and equipment, and any excuse to buy more tools is a good one.

How about posting some pictures of your bought or built cages and what you like about them?

And a gratuitous shot of my new tool storage... ;-)) Sorry about the poor quality - camera phone...

This thread is brilliant. It will keep you busy for a while.

I have a few pictures of my roll bar fabrication here on the SpinningHippo site.

Don,

Did you have any problems installing the headliner? Your top bar looks really close to the roof.

John,
If you're using a headliner in your car, the clearance between the top bar and headliner should be considered. I had a custom roll bar measured and made when my car had no headliner, now it may be an issue.... just some things to keep in mind.

Here is a cage I built this summer for a car I'll share with my race partner. Though it's a dedicated track car it will only see lapping events and solo I competition, and maybe some vintage lapping but no competitive wheel to wheel stuff. Our objective was to keep the car as light as possible yet meet the safety guidelines required by our local club. 0.095" wall 1.5" dia ERW tube. Only extra material is the shoulder belt bar on the passenger. I estimate it took me about 40-45 hours to build, picky about tight fit...

The only thing I didn't know and didn't bump into when researching what to do with my cage was SCCA (I don't race SCCA) does not allow for a bend at the peak of the roll bar and PCA does.

I like how close to the A pillers this cage is

[Az911]

Why not just have some build a copy of the 993 Matter cage?

[Jim2]

chrisp, don't put a bend in the top center of the hoop. Though I did this, it was really pointless. It certainly limits acceptance by different sanctioning bodies. Especially if you take your car to multiple tracks and events.

Thanks for the great information guys. I'll probably start doing some CAD work on the cage soon.

I may start with what Don has done and put the rear portion of the cage in first.

I need to go through all the rule books to see what they say about tying down shock points with the cage. I really like what Jim has done with that.

The hard part will be deciding when to pull the car off the track for a while to do the next transformation. I wish I had a spare non sunroof tub to clean, strip, and install the cage in, then move my components into.

Saw a cage I really liked at the track this weekend......

Thanks to the owner for letting me crawl all over it and take pics.

Joe, Does this mean you are going to come play with us at the track?

So, does anyone know a good steel tube supplier here in Charlotte? Must be someone around with all the race teams in the area.......

[John Brandt]

deal me in

Here is mine:







Remember, mine is a 912 chassis with a Type-4 engine.

[jhelgesen]

Found a supplier for tubing, 1.75x.12, can get it shipped to my office in 20' lengths.

Anyone have a guestimate on how many feet a cage takes? Figure I'll end up ordering enough for at least 2 cages (or enough to mess one cage completely up)

Call Zuffehnaus 704 821 2546. They build cages for a lot of people in the South and I am sure would point u in the right direction.
