Pictures of ROLL BAR in 4 Door??????

[72nismo1]

I'm going to start figuring out how to build a roll bar set up in my 4 door 510 but I want to still have access to my rear seats. Anybody in here have any pictures of there set up?? Looking for ideas. Again car will have rear seats in it.

[okayfine]

Access to rear seats, or plans for rear seat passengers?

Off-the-shelf rollbars fit the same in a four-door as they do in a two-door.

Rear seat passengers.

Then you're going to be looking at a custom cage and spending a fair mint to ensure the builder has the freedom to make the cage as unobtrusive as possible. I wouldn't put anyone in the back seat with any of the standard, off-the-shelf roll cages, and none would allow entry into the rear of a four-door through the rear doors anyway.

I guess I will be the 1st to have one fabbed in a 4 door with passenger access.

Are you planning to build it yourself?

I plan on building a cage for my 4 door pretty soon. I'm not going to go overboard with a bunch of bars. My car will rarely see the track anyways. Just want something to stiffen it up a bit as well as ad some protection. I wont be running any bars near my head, just to be safe incase I do get in a wreck without a helmet on. A nice roll bar pretty much sums it up I guess haha. Mine will be something simmilar to the pic below.

As far building a cage in a 510 that is safe for people in the rear is gona a very difficult. Steel tube next to someone's head, even if padded is going to destroy a skull if in a wreck. Anything is possible though!


Anyway here is a pic of one. Not my car.

Here's a pic of my buddies kid in the monkey bars of my car. Although it is a two door, it has a functional back seat with stock belts. Entrance is though passenger side only and can seat one person somewhat comfortably in the middle. This is all depending on the mounting location of the rear bars of course. Mine are not very structural cuz the're welded on the rear wheel inners' to make the seat fit (and even thats TIGHT). A more optimal spot is on the floor just above the rear spring or if your running coilovers, near the top of the stock tower. Better cage but no seat. I always thought a neat design would be if the rear bars followed the roof and down the sail(C) panel. But that would put a bend in that bar and probably a big no no in the rule book.

This is what I was getting to. Are you doing this for street use? If so, that's one thing. If you need this roll bar to be legal for any racing class, then I don't think it will be possible to retain easy access and use of the back seat due to the rules. If legality isn't an issue, then you're free to do as you wish, but please heed SD's advice and keep the bars far away from anyones head. I was driving with my 8-year-old son in the back seat, not fast, with traffic, around a sweeper. There was a sharp dip in the road surface, and his head smacked against the rear 1/4 window. If this had been a fixed steel tube, with a little more speed, this innocent dip in the road could have caused real damage.

Plan ahead and post pictures.

Yes I will be doing it with some help from a friend.
Yes I only want it for street use not for Track.
So that is why I would like some ideas on how to make.

My idea is similiar to McShagger510
" I always thought a neat design would be if the rear bars followed the roof and down the sail(C) panel."

Any other suggestions or pics let me know.
Thanks


Planning on using 1-1/2 X 095 Wall ERW Tubing.

If you're asking for advice on cage construction, perhaps this isn't a project you should undertake. If you don't understand what's involved, it's quite likely anything you make will be compromised, perhaps to your (or your passengers') detriment.

There is plenty of research you can do to educate yourself, but most of that isn't going to be here. There are a couple cage builders on The Realm...I'm not sure they'd offer up suggestions without more confidence in your abilities.

The question that I have for you is why do you want a roll bar? Safety? Chassis stiffening? Bling?

There are many elements that go into building an affective roll bar that is both safe and aids in the stiffness of the chassis. Unfortunately that does not include rear seat passenger safety/comfort.

If you really only want it for bling, I have seen some examples of roll cages in Japan that would easily maintain access to the rear seat.

[72nismo1]

I would like it to do all 3 things. Safety? Chassis stiffening? Bling?
If at the end it is not do able to clear for rear passengers I would probably be ok with that.My 510 is not a daily driver.

So I would still be interested in ideas if anyone wants to share.

Have you even bothered to search here? There are a few roll bar threads, with much commentary in SacPop's race car project thread. Beyond that, what "ideas" are you looking to have shared?

[72nismo1]

No I have not really looked yet. I will check it out.
