Are subframe connectors needed if you have a 6 point cage? Doesnt the cage provide the same function as the subframes?

 

saftey wise NO, but I think you were talking about improving the structural integrity, so in that case yes. I am sure if the cage is connected the front and rear sub-frames it is good.

 

Yea I just looking in the area of some weight savings. I didnt see the sense of having "double" duty so to speak.

Anyone else have an opinion?

 

I plan on having both. I like the heavy duty approach and having everything very rigid. If the little extra weight got to me id just plan on adding more power

But thats just my opinion, others dont have to have the same.

 

Point well taken kmook...the extra ridigity cant hurt...

 

when i asked i was told yes-

the subframes and cage wont really "double" up on anything.

 

I have both and am glad for them. the car is very ridged.You can jack up one side at a time save time in the long run if you work on your car as much as mine

 

The strongest structural shape is a triangle. The front brace and the rear upright make up two legs of the triangle, leaving you with nothing but sheet metal for the third leg (the rocker panel). Adding the SFC's will give you the third element of the triangle, and provide the greatest strength. Another thing to think about.... if you go with swingout side bars, depending on how tight the pins are, you might lose some of the rigidity in the front braces.

To save about 1/3 of the total weight, have the roll bar made of chrome moly. Could be worth about 30# savings.
