Default Need roll cage help

I have a 06 Subaru WRX and I am interested in using it for rally races, while reading over the rules and regulations for Rally America and some local events I noticed a re-occurring requirement a a roll cage so my questions for you are....

Do you buy a pre-shaped cage for your specific car? If so where can I purchase one.

OR

Do you just buy metal and shape it to your car?

If neither please inform me.

The cage and safety rules for both Rally America and NASA are pretty substantial. Both are nearly in alignment with FIA safety cage rules, so you don't want to cheap out there!

E.G., probably better to leave the cagework to a shop that specializes in rally and road racing cages, stay away from the average drag race or circle track cage builders!

There are cage 'kits' that are available. SafeDrives sells a weld-in cage kit that is Rally America legal. As well, Custom Cages from the UK sells an FIA-homologated cage kit which fits very well (however being FIA homolgated the kit cannot be modified, it must be installed 'as designed'). There are a few vendors in the US which distribute them and can install them as well.

Of course, you could have a shop make a full custom cage from straight tubing, or you could buy the tubing, buy a welder, buy a tubing bender and then do it yourself. I would forgo this route unless you have substantial experience welding and bending/designing cages. Your rallycar is really no place to start practice your welding and fabricating skills. When you crash (and ALL rallycars do crash eventually), you want to have the best cage possible around you.

Best of luck.

Are you experienced in rally? My concern is that you'll get a cage welded into the car before really understanding what you are getting into. For example, does RA allow novices to run AWD turbo vehicles?

If you know all this, sorry for assuming the worst. If not, maybe some SCCA Rally Cross events are the way to start?

a place that does mostly drag or circle track cages would be alright, as long as they actually have the skill to do quality work. all the basic skills are the same, just got to make sure they know what is and isnt required for the cage, they obviously cant just throw a 9 sec legal drag cage in a rally car and expect it to have to live up to the same rules.

and i agree with not attempting it on your own, not without a lot of practice before hand.

I absolutely agree that the skill level (can) certainly be there, especially with the drag racer cage builder (TIG'd chromoly tends to need greater skills than MIG'd ERW tubing!). I'm merely pointing out that if they don't have the knowledge of the rules, then they may tend to steer the end user away from the appropriately legal cage due to infamiliarity with the rules on their part. If they are however willing to work within the ruleset and have the skills, they can do the job quite well.

I think what you ment to say is stick with a shop that has the experiance.. i.e. and road race or rally builder. Not a circle/drag shop... while they may have a fabulous welder.. it requires much more thought. Bar placement is very crucial... drag/circle guys tend to do it their way..having never really had to pass a sanctioned tech insp before.

(I have seen a 9 sec drag car that ran at a VERY high level... bolt in cage covered with JB weld)

Best is to stick with something proven.. (A KIT).
