any roll cage builders i am curious to know...? sizes, thickness, blah...material...types, ...etc...

also what is your best proven method of bending the metals?

and does anyone make their own strut bars, and X bars, or any other brace bar...not a cage..what are your designs?

also where to buy lengths of these materials

crush bent exhaust tubing is what I'm rockin in my mAd RyD3!

Just kidding...I believe the metal of choice is chromoly steel. It's a great steel alloy with excellent stress and shock characteristics.

 

In most cases, the rulebook dictates materials and dimensions, as well as some significant manufacturing processes and geometry. There is room for creativity you will need to start with the standards required by your sanctioning body.

Have fun!

gotcha...interesting...i dont auto-x but thought this would be the place to ask...wheres the links to the rules...?

 

Bzzzzt.... wrong...

Chromoly is harder to work with and must be TIG welded - the material of choice is DOM steel, there is no weight advantage for chromoly like there is in drag racing as the tubing thicknesses must be the same no matter which material you use.

Dont spread misinformation please.

No links for SCCA. You gotta buy the book. The NASA GCR, IIRC, mirrors the most restrictive SCCA classes.

 

ALL SCCA cages must be built using a DOM or ChromeMoly type tubing. As noted-the rules for 2003 are very specific on materials, construction and installation requirements. The NHRA/IHRA rules books are also excellent sources to learn what is needed for those 2 sanctioning bodies-and they are somewhat different from the SCCA and NASA rules.
If you elect to use ChromeMoly - find a fully certified welding shop that is experienced in doing drag cages with this tubing. This is an opinion, but links to the importance of weld quality. If you use DOM, including Shelby process, find someone who has done fabrication with this type of metal and has all of the needed tools for the job. MY cage was fabricated and the 'main hoop' assembly welded by KIRK Racing Products. The halo and down tubes were bent by them. Final preparation and installwas completed by my fabricator (NHRA/IHRA certified).
Good luck

thanks guys...anymore info i need.? also what about drag, ghow theres one size only?

 

Are you building the cage? For what kind of car? What series/class?

 

i am going drag right now, just getting info on best materials and such..but would like to get into circuit soon though...hey my sister goes to madison..and i appied there for freshman fall 2003 but dont know if ill get in with my crappy GPA due to laziness and alright SATs...u dont just happen to know someone t help do you? ill join ur motorsports club if i get in

 

I want a CF cage.

lol...dont we all
