Roll Cage...

[goodcookiedrift]

increasing the rigidity of one area of the chassis without addressing other areas such as joints and seems can cause those weaker ares to buckle and fracture under torsion. that is why seem welding and cages go hand in hand.

Alrite.. i have read through all of the post.. but one thing still confuse me... is that if you say you can't just stiffen a part of the car without stiffening out the other...
then what's the point of 4pt, 6pt, 8pt, etc. roll cages? do they offer the same rigidness but with more bars? i always thought the more pt rollcage the stiffer it is... so is it the best to get the most pt rollcage to balance out the whole car's unibody? still confuse ... but still intrested in getting rollcage...

Ya post pictures for sure

The exact points where the cage is welded should be well calculated to even out the stress and flex factors. Also the length and angle of certain bars in relation to others will also have effects on how the strength is distributed.

Ok, well all points are valid, and well taken. I think I will look into this a little more before deciding what to do.

Thanx

Is it the same with subframe connectors?

Oh icic... so the more pt the more stiffer? Also how many pt rollcage should be enough for a 70% track 30% street car? I'm leaning towards 8pt rollcage... :wink:

your roll cage should be constructed based on RULES that certain racing organizations allow. if you just want a cage for minimal stiffness and really have no interest in entering certain racing events, i would say go with the bolt in cages or just get a 4 pt made.
