Hi, Im actually looking forward to buy a sedan Integra, im planning on making some improvements to it, nothing too obnoxious BUT as its an old car, I was thinking the probability of using a roll bar (not cage) on it as a street car.
How safe it is? I was thinking of the kind of bars that only go on the rear part of the cabin:
!!! UNKNOWN CONTENT TYPE !!!
So What are your thoughts oppo? is it safe? what about adding some padding to it?

Yo, that Integra will look sick, brah. Totally go for it. Integra sedans are seriously fast cars brah, so you better get it powder coated to match your rims.

I do in my Z, can’t hurt. I have considered side impact bars too. Mine is a 71' so crash safety was not really good.

If you go with a roll bar, padding is a necessity (unless you’re just tracking it and always wearing a helmet). Not just a cut up pool noodle either. You need high density foam covering every part of the bar you could possibly touch when in an accident.
Also, make sure you’re getting a good quality rollbar. A subpar bar will be much worse than no bar at all in terms of crash safety. A lot of people and companies make rollbars, most of them don’t get the proper geometries worked out. A good rule of thumb is to only go for bars that are approved by racing agencies.
Rollbars are great if they’re done right. Your car will be MUCH stiffer, and you’ll have the added peace of mind. If you’re ever in socal, go to blackbird fabworx and talk to the owner Moti. He’s a legend in the Miata community, and makes bars and cages for many other makes as well. And everything he sells is approved for all major racing bodies, which is more than can be said for any big name rollbar company. Good luck!

It’s your car, do want it to have a roll bar, or to actually be protected In a crash? Two different things both equally valid.

My car has a half cage... it’s best if you are not required a full cage due to racing regulations. Mine is set far enough behind my head that there is no way I’d hit my head on it in case of an accident. Having passengers in the back (Japanese sa22c are all 2+2) is more problematic though. In case of an accident, they’d hit their head on the half cage directly and most likely die immiedately. So yeah... I avoid taking passengers in the back :)

I was going to ask the same question.
I would only put a cage/bar in a car if it was required*. Unless there was some track requirement, it’s the last thing I would put in a car.
With the exception of maybe a roll hoop for a convertible.

when does a roll bar become a roll cage?

This sounds like a terrible idea if you aren’t going to be tracking it regularly and don’t want to wear a helmet when you drive. Putting solid steel closer to your head is going to increase the chance of a major head injury in an accident.

That would be a half cage. I’d say when it has more than two mounting points it’s a cage. Alternatively, a roll bar is what you have connecting your left and right hubs.

I would say padding is important even with a helmet... hitting your head on hard objects hurts, even if you’re wearing a helmet.

If the car is a daily driver, I’ll say avoid the roll bar/half cage. Though there is extra safety to be had in more extreme accidents, it also ups the chances of injury in more minor accidents. A lot of that downside injury risk is mitigated with harnesses, seats, and helmets, but that means you would be using harnesses, not so comfortable seats, and a helmet regularly. Those are not convenient for every day use.

I happen to be getting my old racecar going again after letting it sit for way too long. Back in high school when I was building the car, I drove it with the roll cage for a couple of months before buying another car to drive on the street. I wouldn’t recommend a cage on the street. Even my 18 year-old self thought it was a pain in the ass. The middle-aged adult me wouldn’t even entertain the idea of it now.
A roll bar can work fine on a street car, so long as the rear seats will never again be used as seats. Done right, you could have a race shop fab up a good enough roll bar to serve as the back half of the roll cage for when you’re ready to really make it a racecar. Bolt-in should be avoided, and a diagonal brace should be considered mandatory if you’re actually looking for a safety item, along with legal mounting plates, DOM tubing of legal diameter and thickness for the weight of the car and sanctioning body you want to play with.

When it has a front hoop, down tubes and door bars.

Structural foam in the frame rails makes a huge difference. And you can’t hit your head on it

If you’re ever in socal, go to blackbird fabworx and talk to the owner Moti.
I just installed my BFW bar last weekend, and I’ll vouch that they make nice stuff. As far as I know, Moti will only do bars that are SCCA & NASA legal, which most tracks will require. And if you are going to go through the work of installing a bar, why install one that won’t be accepted at the track?
Also, worth noting is that the bar in the top image has no diagonal. It will almost certainly NOT be SCCA legal without some triangulation to prevent deformation in a side roll-over.

I will be putting a roll bar (have it just not installed) in my Sprite because I am 1. taller than my windshield and 2. there is 0% safety in a roll over.

Thanks a lot for your input man, yeah I am totally aware of the need for it to be a certified/approved part - I’ve seen many disastrous and ridiculously made rollbars, a fellow friend almost lost a leg on a crash where a shitty rollcage was made.
Also I know padding wont be the end all/be all solution but somethinf if good quality could help a lot.

Because It will be a street car that would see track time sometime in the future, as the local racetrack asks for a rollbar I wanted a good mid point between something safe/useful and something streetable, besides I dont feel that safe in a 90s econobox so thought if properly done could do good both in safety and handling.

Hmm refer to the other reply - local track asks for roll bar and would use the car on the street too, if wanted to be a dumb stancekid oppo wont be the place to ask, and would have probably already bought some fiberglass piece of shit. Yeah, ive seen plastic fake rollbars.

Excellent answer my man! Thanks for your input, yeah thats the only downside, safer for front passengers, deadly gor rear passengers. Talk about black and white lol

Im totally on your side, but my question is, lets say its half a cage, would still be deadly? Like im not comparing aftermarket engineers with porsche ones, but I bet my ass the gt3 rs roll bars are totally safe for street use, right?

03/03/2017 at 19:05, STARS: 0
Thats one of my main issues, the car would be seeing some track time and local racetrack asks for roll bars, the thing is i want to drive it on the street too without being deadly in a street accident, thats why I asked for roll bsrs or half rollcage, Im not sure but I think half a cage properly padded and located would certainly help a lot in a collission. Ofc it would be deadly for rear passengers but then I would avoid having passengers st the rear at any cost

Oh it has a back seat, yeah the main thing with front or back seat bars with no helmets is whacking yer head. My Z has it all behind the seat at the moment, 2 seater. If you want passengers it is an issue for a sedan unless it can be right over the front seats and they wouldn’t lean into it moving forward. I would be careful about that.

Yeah, the GT3 RS one is, and I guess I should have noticed that you were looking at half cages. As long as you don’t intend to use the back seats and the bar’s well behind the seat, it should be okay, but I’d still be looking at a welded cage instead of a bolt in one. There’s a reason the SCCA doesn’t allow bolt-in cages and it’s because they have a tendency to just punch holes in the floor in the event of a rollover.
