Class 11 roll cage.
 

What do you guys think of the weld in roll cages that are sold for baja cars for $160 dollars. They say they are class 11 and score approved whatever that means. The name of the brand that looks like it will best fit my car is "Chenowth"? The reason I want a cheaper weld in roll cage is that I have a modified fire wall and none of the bolt in cages will fit. I don't mind cutting up a $160 roll cage but I mind cutting up a $500 roll cage. I also want to weld in some front shock tower cross mounts like the yellow remmelle bug in the galleries to stiffen up the chassis. Any input would be helpfull.

Anybody got any ideas :confused:

How much weight does a roll cage add?????


I think I want a 10 or 12 point roll cage.

A 4 point cage touches the chassis 4 times and a 6 point cage touches the chassis 6 times, am I correct????? :confused:

For a street style car, I think the "Class 11" cage is a bit too much. The cage has mounts for the top of the rear shocks built into it and doesn't follow the inside of the car very closely. In a Baja it looks right at home, in a car with a nice interior it would look rather crude.

As Jerry D said it wont look at home if you have a full interior in your car.
Also consider the different needs in these applications

I mean in off road is easier to roll over so the cage must be thicker and have more suports in a circuit application u can use thiner tubes and in road application u can have less mounting points (due to supposed normal driving).

but its all ur call at the end.

Be very careful if you decide to cut some tubes off a weld in 11 point cage as it might reduce to overall rigidity of the cage.

What I was originally thinking of doing was to add a cross brace from the front down tubes by the dash in a X pattern to the front shock mounts for rigidity like the remelle cars I have seen. I have been thinking of ditching the roll cage idea as it will divert my money and time from the rest of the project. I will only have a near stock 1600 or a near stock 2.0 type 4 so I won't need the roll cage and when I get more power I will add a NHRA approved bolt in roll cage. :D

You would be better off making friends with your local roll cage builder. Tubing is cheap, even chromemoly, and really the labor time is not great on someone that is an experienced notcher. Having all the right tools makes installing a cage a simple affair. Try to find the guy that does it as a side job and maybe you can help and learn all at the same time. If you were close to Austin, Texas I would tell you to bring it by my FX shop. I will try to post our latest movie cage, a real notching nightmare...

Sorry we are not closer.

Thanks for the offer SuperRSI.... The more I think about it the more I would rather leave the roll cage for the race car. GL#2... :D I haven't even finished my first car and I'm already thinking of the next car... Somebody stop me.. :D :laugh:

From the beginning of my project (almost two years ago) i wanted to make my own rollcage.. Expescialy I wanted to use chroomolybdeen (the steal were most rollcages are maked from) but the local stealman. said that this was way expensiver then extra strong steal (an higher S-class of steel).

ANd also the baddest thing is that you have to have some other gas and weldingwire than on normal steal (that's what the stealman said.. is this true???)

My cage also wil be an big cage.. with pipes through the front to my veerpoten (don't know the english word of it)

Greetings Wiebrand :D

Hello,

Veerpoten = front struts ;)

Cheers,

Chromoly is nice but its not to mess around with. Many people get away with not heat treating the steel agian after its welded but a regular steel cage will probably beat a improperly treated chromo cage anyday. The trick to cages is getting the tube bender (no you can not use the orange PIPE bender from harbor freight). To my knowledge their is only to places to get a decent hobbiest bender and thats the protools bender and the JD3 bender.

I know that..

I know people who has an electronic controled bender and they have also hydraulic benders
