Hi,

I'm building the roll cage for my new asphalt street stock. I've seen two different styles for front roll cages. I'm not sure which one to go with.

Check them out here:

Which style do you use? Recommend?

I'm not sure of the pros/cons for each type and I've seen both of them win races.

What do you think?

Thanks,
Sal

its funny cause on almost any pavement street stock i have seen i have seen them running A. all the dirt street stocks that i have seen most run B. and i have allways wonderd why this is. seems to me that B would do a better job of protecting your radiator.

crash tested it a couple years ago. rearend a stopped car going about 50. The bars infront and beside the radiato were munched along with the radiator but the angled bar right behind the radiator saved the motor.

I always run two bars from the front of the cage to the horns instead of one hoop .My theory is that if I get hit from the side it only bends one horn.But you still have to tie together to protect the radiator support.So I really dont think one design is better than the other its just whatever you prefer they both weigh about the same .Enduro80

I personally like A and thats to the effect of what i will be putting in my new car, you can build the crush zone into the front of the car. Eddie

The benefit I see to design A is that your radiator support/protection is seperate from your frame support/protection. That way if you take a hit in the front it should, in theory, allow that to be the crush zone without harming your frame supports.

This way all you have to do it build a new radiator support and get a new radiator and go.

With design B any kind of hit you take in the front will be transmitted directly into the frame and the rest of the car which I would think would cause more damage.

I would personally rather have to replace a radiator and build a new support for it rather than have to bend the frame back out, cut and splice new tubing into the bent up front hoop, and replace the radiator.

Goes back to, do you want a tank or a racecar?

Just my take on it.

We have a Wayne Larson car and it is more like style A. That is probably what I would go with. I think that a seperate support for the radiator is best. I would also use pegs coming up from the stub for the fenders. We had a lot of problems with bending our radiator mount until we put our fender mounts coming up from the stub. I would also use a bolt in bar going over the motor in front of the carb. I think it makes the whole front end stronger.
