Roll Cage, Going to do it this spring Options

[jcbass7]

So my pal (fellow Coastie) was showing me some pictures from home(Washington state) and i stumbled upon pics of his jeep. well he explained to me that the 5 pt. roll cage on his jeep, he made by himself, bending welding etc. I was extremely impressed by his work and we got talking about it and we are going to put in a cage in my car. Something similiar to Tufy's but i am not totally sure of what i want in the end. Definatly want to stiffen up the REAR of the hatch. My coupe was a lot less flexible in the back and i am looking forward to some serious support back there. i want to keep the cage somewhat tame though, as i want to build custom fiberglass enclosures after i have the cage installed.

The plan is to build something like this:

i also want it to be removable, with little to no permanent welds into the car. but if we can't avoid it then oh well

any one have any comments, questions, concerns?


EDIT: ps this is not incase i roll over, its purely for chasis rigidity and a little bit athstetics

IDK, jesse...IMO building ANY type of roll cage is NOT a place you wanna be experimenting and learning at all.
IMO its really not worth the risk, besides the fact that its not gonna stiffen the car as much as the other stuff people here are talking about.

wouldn't be expirimenting, since i have someone who used to do it for a job with his father helping, but i am starting to look at the points people are making about it not stiffening as much as i want it to

my hatch w/coilovers and a gt4 rear bar could oversteer
and purplegt4 has TEIN SS w/sways and his car is tight as a virgin

roll cages really arn't ment for "stiffening" of the rear...you just need to work on your suspension setup better

Ok so say i build a 3pt front and a 3pt rear, what other custom peices could we fabricate to help out with handling?

Also, what should i do for a harness bar then? Just weld a cross member between the B-pillars?


once again i want to thank everyone who has offered input, it is definatly helping me form my opinion on everything.

PS: these are my current susp mods and future plans

gt4 rear bar
stock front bar
kyb gr2's in the mail right now
tien s-techs waiting for kyb's

I can't afford Tien SS coilovers

and susp tech sways are coming next paycheck


If i drop the cage idea:
3pt custom rear strut
3pt custom front strut

^ what else.. i could do side tower braces
