Chromoly vs Mild Steel
How much weight savings?
I have 01 f-body and need to get a cage.
I was thinking weld in 5pt instead of a 6pt to save weight with a swing out.
How much weight would I save with that style of cage......chromoly vs mild steel?
Thanks

the right way to find out what you guys need to no is contact your division headquarters be it nhra/ihra they are the ones who make the rules ,or contact a competent shop who build cars ,also a lot of guys are calling roll bars cages this is also wrong [this is quite common]so when some one calls for quote first we have to find out what they are talking about :drivepro
heres a paragraph i made for the fast ls1 site [it is also post in ls1 tech a few times as people asked ] alot of people are useing the wrong terminoligy] ,a cage is a cage and a roll bar is a roll bar[a roll bar can have 5pts 6pts 7pts and8 pts,a cage can have 6 pt ,8,10 12pts] a lot of people call up for cages and their trying to ask for roll bars its a common mistake
,most cages are actualy are 6pt unless 2 diagnal bars go to tunnel or frame connectors[before everyone jumps on me the 2 side bars usually go to the front uprights so unless you have the 2 diags like i said and they are mandatory when a cage is put on plates[pge 209 of rule book see diag. read D] if its a chassis car[ ie chevelle,malibu,corvetteanything with a full frame under it]the cage then has to be mounted to the chassis and dosnt require the 2 diags to tunnel. what else is needed are ,a window net,padding anywhere drivers helmet can contact[pge 203], and the instaler should put tabs for required shoulder harness [so its bolted to spine bar and cannot slip off you in case of accident]and if you go faster than 9.99 a chassis cert that should cover the basics hope this helps.
and we have not done mild stel anything in like 5yrs,so C/M it is bob

When trying to figure the weight difference consider that MS has to be .118" thick wall and CM only has to be .083 so a CM rollbar is 70% of the weight of MS.
Example: if a MS weighs 75lbs. then a CM of the same configuration would weigh 52 lbs.

so the difference between that and the CM is @ 33%
we have wieghed it several times through the years, bob
