Hey...
I've been researching all sorts of roll cages until now. I have finally come up with the idea of welding up my own. I have a few simple rules...(BUT first off, i have researched this topic)
ALSO... i have read both NASA and SCCA rulebooks. These questions are referred to the rules.
I WANTED TO KNOW:


1) The minimum size for my wight class is 1.5 x .9.....im thinking about .120, but what about tube diameter...1.75??maybe?


Thank you for your time in advance...also i will greatly appreciate it if people can keep there useless comments out... because i just want quick answers from different people.
THANKS AGAIN

Do you plan on doing track events (HPDE's or Time Trials) or mainly autox? Usually a roll-cage is over kill for autocross.

 

For a 92 civic, 1.5" x .095 is legal, but most of the time you have to ballast those cars to get them to meet min weight anyway, so I prefer to use 1.5" x .120 tubing for this application.

No, you don't need a certified welder to pass tech, but the tech guys are getting MUCH more thurough with their inspections so your guy had better be good or you may find yourself doing it again.

Building cages is not rocket science, but there are a few little tricks that make the difference between a good cage, and a cage that you will find yourself cutting out in a few months. So I would make sure you know what you are getting into. I would recommend spectating at a local SCCA or NASA race event to get some ideas before you start. Good luck!

 

Don't bother with the expense of a cage if you only autocross the car. If you street drive the car also, definitely don't bother with a cage. Maybe a roll-bar if you really want *something* there.

As far as passing autocross tech with a cage... I venture to say that nobody ever teched my roll-bar in my miata at an autocross. Including at Nationals in Topeka. You can have style bars and pass (thinking those little hoop things people put in their miatas). For autocross, they are typically extra weight, and nobody generally wants that if they want to be compeditive.

 

im really sorry...here is a corection. My car is not for streets at all. I ntend to race with it only. BTW when i say race, i mean something similar to Honda-Challenge H1 class. So it isnt just for "Auto-X" this is serious road racing

the reason why your not getting any other answers is cause this is what most people do.

 

so are most rollcages 1.5x.12 r around there???
