Questions on roll cages

Q: If the goal is to make a drag weapon (as opposed to a daily driver), how built up is your roll cage. At the ETs you guys are running, do you already have a full cage yet?
If so, is the cage tied to your front/rear suspension points?

Here's an example of a rollcage that's almost a "car within a car". I especially like the plates that tie the shell whenever it comes close to the roll cage structure.

A bar is all you need till 9.9's. Then a cage is required!

Most all of the legal drag racing cars on here presently use bars. Once into that 9 second zone then a cage is a must legally.

did you use mild steel or chromoly?

that's a lot of work to weld all the seams. If I was stripping my whole car, I'd likely do the same. But I'm not, lol.

What is the difference between a "Bar" and a "Cage"?

For the "Bar" the pipe is following the inside driver B-post, roof and then passenger B-post? And obviously the cage is what Nick has?

Thanks,

I can't see having a roll bar in my car. I like the interior the way it is. I'll have to keep it slow, but on the other hand if I had a rockin drag car I'd cage it out like a jail cell. Thanks for the 101!

I know its being a smart arse but...

At my local track the only requirement is a helmet, but then again its the only wildcat track left--no NHRA.

If all else fails get a bigger hammer!

A bar isn't too bad as long as you don't need to get in back. And it stiffened the car up alot on mine. Riding with the firm ride off now is like riding with the firm ride on before the bar.

I expect it is in your line of motorsports. Most cars on here do not need nor do they require a cage. Thats all I was saying. Some refer to a bar as a cage, but they are not the same.

There may be some soon entering that zone soon though. Regardless bar or cage, it's all for the protection of the driver and safety should be a priority.

role cage



So I have yet to see a role cage in these pictures.

You can see some of my cage in the beginning of this clip.

Here we go again!. Either NHRA or IHRA require anyone running under 11.50 or 11.00 dependant to have a required Roll Bar regardless! Lap belts and helmets and fire jacket are also required among other things.

Minimum of Bar/Cage is required with either sanctioning body once you start exceeding the 135 MPH barrier.

I know you all skirt the safety issues but this is what the facts are to be legal.

The new NHRA rule is for Sedans from 2008 up that are unaltered in any way to run down to those numbers. Of course, like everyone else that is at the discretion of the track personnel doing the inspecting which at IRHA that I've seen are sometimes very lax.

That being said I'm not getting into any safety issues with the cars. BUT, ROB and YOU BOTH know what should be done concerning his cars. Nuff said.

You won't be doing that but once at any of the tracks up here for sure.
