I am posting these here because I have alot of trouble finding pics of this cage installed before I bought it. This is for reference so that if someone searches its available.

The cage fit pretty well, only 1 door bar needed notching. Its not as tight as something custom but it gets the job done. If I could do it over again, I would get a custom cage because in the end I spent the same as it would cost for a 6 pt custom chromoly.

It was welded using ER-70S-2

 

Fitment looks kinda crappy actually....

but better than S&W.

PS. you should have used different filler. ER80S2 is what you want to use.

 

it doesnt look to awful to me...do those bars behind the seat have to be so close to the seat?

 

if it is just mild steel, then you used the right filler. if it is cm, then you would have been better off with 4130. are you planning on adding any other connections to the frame like along the a and b pillars or across the roof line? that is a good idea and will strengthen it immensly and make it much safer.

Q. Why is 4130 filler metal not recommended?
A. 4130 filler typically is used for applications where the weld will be heat treated. Due to its higher hardness and reduced elongation, it is not recommended for sporting applications such as experimental airplanes, race car frames, roll cages, etc.

Q. What filler material do I use?
A. Although there are several good filler materials, ER80S-D2, is one you should consider. This filler material is capable of producing welds that approximate the strength of 4130. ER-70S-2 is an acceptable alternative to ER80S-D2, as is ER70S-6, although the weld strength will be slightly lower.

I personally didnt weld it, but I did research this topic before choosing the filler, and like said above I believe 4130 will need to be heat treated and we couldnt find an oven big enough to fit my car in lol

the seats move in all of the factory positions (minus reclining) they are all the way back in the pic.

I agree, its not nearly as tight as a custom cage would be

Well, you missed the bit of research that states that you don't need to heat treat cromoly until you reach a certain thickness. For .083 it is not necessary. Using the ER70S2 you lost quite a bit of tensile weld strength. You now have a greater chance of the welds breaking, if anything were to happen, instead of the cage doing what it is designed to do.

SAFETY FIRST!

 

IM SO TIRED OF READING FALSE INFO ON HERE! First off, cage looks great man! Dont take any shi*t from anyone!
Secondly, tepid...go somewhere and learn what your talking about before you open your mouth. ER70-S2 is perfect for a 4130 cage. If you knew what you were talking about, you'd realize that the reason 70-S2 is used is because it does flex, and is not brittle. If you were to use 4130 filler, and smacked the wall, the welds would break/crack, is it is VERY strong, but VERY BRITTLE, and would crack.
DONT STATE FALSE INFORMATION! ER70-S2 is used by all chassis companies in the country! Dont fool yourself!

You have got to be retarded.

The ER80SD2 will be the closest to the strength of the 4130, and have good elongation properties, so it wont shatter at the welds in a hard impact. The only thing that I like about the ER70S2 is that it is easier to keep contamination free and that is what's important. You can compensate for the lower tensile strength by using more filler in the joint. The difference isn't huge, but worth noting. If I remember correctly ER80SD2 is 90,000 psi vs. ER70S2 is 83,000 psi tensile strength. Normalized tempered 4130 is 90,000 psi. It only makes sense to match the filler to the material so that there is a global transfer of force when bad **** happens. There is no one weak link unless it is welded incorrectly.

 

er70s2 is what i use on all my chromoly, as does vanishing point racecars. i buy all my material from them. and they recommend er70s2.

 

I as well as almost every chassis guy i know uses ER70S2 on chromoly.

You're owned for not spelling correctly you dumbass....

 

tepid...what did he spell incorrectly?? hahaha. he spelled everything correctly. sorry you are wrong, but at least admit to it, or say something to the effect of "okay, thats cool, but i am going to continue to do it my way..."
come on now.
By the way, Keith and Jim Geese and the rest of the guys over at vanishing point racecars are GREAT guys! i do alot of work with them...

Actually he spelt my username wrong.... looks like you need to pay attention to detail too....

Anyway. I provided my input and reasoning. I will continue to do it the way that I do. Chose any method you want. According to everyone else, it appearantly doesn't matter.

New cage in my car

 

Well, Im not an expert or anything, but that cage looks pretty damn good for the purpose your using it for.

Add that to the BS. I have the S&W and I can't see a difference. Especially when S&W or Full Race doesn't drop the thing into your car for you.

 

my mom can kick your moms ***!!!

 

OK boys, do a Google seach for welding 4130, check the welding supply and the AWS page. The preferred rod by all is ER80-S2, then ER70-S2, ER70-S3 and the ER70-S6.

Not all chassis shops use ER70-S2, how could you even make that statement? I have spent time at Walker Evan's Shop building SODA and other Off Road 4130 chassis. They didn't use ER70-2, only ER80-S2. Every Pro Shop I have been in where they build chassis to sell in large volume used ER80-S2. I would think it is a preference by the shop.

The kit is pretty decent. I am surprised it fit as well as it did.

 

to the topic poster -- the cage looks great. Im sorry to hear you are not happy with it but it looks excellent.

 

ER80-S2

 

er80-s2 for me as well

 

the height could have been fixed, by lifting it up before welding it in. a slip over pipe or heavy-duty "box" could have done it. that would have tightened up the side angle are also

looks good though.
