Yes and yes. I also had the horizontal bar go straight across and intersect the diagonal instead of bending back and going behind it.

Here is another photo of how he usually does them to compare to mine.



Mine and the one above are based on his "GP Lite"

Here is his "normal" bar. I didn't want all the extra tubing and the extra 20lbs! it adds.

 

Looks like yours is bare metal rather than painted.

Do I win?

How is the chassis thickness where this attaches? Plenty of material to attach to?

 

That jungle gym is nuts. Seems weird to have a rally worthy roll bar without the rest of the cage.

 

Yep no use when the a pillar and roof just cave in around it and you lol. never been a fan of bolt in rollcages either.

 

Most cars these days are required to have rollover protection and/or meet minimum roof crush standards, which if I recall correctly is a relatively new standard (in the past 10-15 years)...

"A good rating requires a strength-to-weight ratio of at least 4. In other words, the roof must withstand a force of at least 4 times the vehicle's weight before the plate crushes the roof by 5 inches. For an acceptable rating, the minimum required strength-to-weight ratio is 3.25. For a marginal rating, it is 2.5. Anything lower than that is poor."

So any car where the A-pillar and roof cave in around you, I would assume is pretty old, and before that standard was required by the NHSTA and the like...so in other words, I think you'd be fine an a 2020 car with a well made bolt in roll hoop....

 

That's where I'm at, but I keep it to myself because I've had people start arguments over it. 🤣
It's a polarizing topic.

 

I've seen a good amount of rollovers the last 10 years and modern cars seem to fare MUCH better than older cars. I remember back when a rollover would result in at least one pillar to be pushed in a ton into the cabin. Modern cars are insanely safer than older cars.

 

Another reason they weigh more too. The side impact requirements in 2017 added a lot of weight to cars recently

 

yea but remember those crash tests are designed for a car travelling at normal traffic speeds. aka sub 120kmh.

Your easily doing twice that at some points on a race track. Of course a modern car will fare better but by the logic your using we wouldnt need Halo systems on open wheelers and modern GT3's etc wouldnt bother having rollcages anymore

 

I'm not talking about crash tests, I am talking about seeing rollovers on the track and street. I also never said anything about not having the need for rollcages and other bits of protection.

I run a seat, six point, and HANS when I am on track.

I think the disconnect we are getting here is that you come in all Mr. Real Race Car (this is not a criticism btw) and we are here with our street cars we use on the track.

 

I think he (she?) may be more so responding to my post..? Since I quoted him..

Yeah, because then mentions:

"Your easily doing twice that at some points on a race track. Of course a modern car will fare better but by the logic your using we wouldn't need Halo systems on open wheelers and modern GT3's etc wouldn't bother having roll cages anymore"

Which I'm not sure how "my logic" would even apply to open wheelers and other dedicated race cars.... Kinda confused by that...

 

Yea im talking about the track, as i assume thats why youd put a rollbar in your car in the first place not for the street. Comparing open wheelers was probably a step too far.

Guess my point is if you have an accident big enough to need a rollbar in a modern car then your probably going to want bars going down the a pillar aswell. otherwise chances are in a modern car that a rollover at low speed the roof wont go anywhere with or without a rollbar.

 

So what I'm reading is: theoretically, modern cars may not need a roll bar because they are safe enough in a roll over. If an accident is bad enough to bring in the roof, it's probably bad enough that only a roll cage would really help. So, the question would be: Are you going fast enough that you need a full roll cage?
Or something like that. haha.

I've often wondered if I need a roll bar in my new car. I'm doing it as a way to mount a harness because I can't do an ASM.

 

At least this roll bar is probably putting the harnesses in the correct position for his seat.

 

Yea something like that. i think the whole conversation fell off the wagon ages back haha.
