914 GT roll bar questions, Dimensions if possible or advice Options

[Mueller]

Are there actual dimensions followed for the GT roll bars installed in the GT cars?

Looking at this picture it looks like the side bars are longer and mounted further ahead on the longs and lower at the hoop than other pictures I have seen.

It could just be the angle of the picture as well?

Reason for asking is I have a friend that bought a 22 foot length tube for me which is too long for me to transport. He is going to cut the tube to fit in my truck, without wasting too much material how long should we rough cut the side pieces?

Ideally how far up on the hoop from the longs should they be attached?

Same question for the bars that attach to the inside of the hoop up top and to the rear firewall. It seems in pictures there are attached in multiple places and angles.

Mocking up the bar in my car:

Mike - I'm glad you can put that bar to use!

I'd copy what McMark did (maybe he'll share some measurements?) but in the end, just be sure you're comfortable with in/out access with the door bars and head clearance on those upper bars. Note all that padding, too.

Keep us posted as you make progress...

Thanks again, it fits great. I will trim the lower portion a tad for the plates, but I was able to put the top on and access the locks with no problem and there is enough room for the padding for the targa top to fit as well.

The green car pictured above is a later conversion so the accuracy of the bar is questionable. I can tell you that the roll bar in the homoligation papers had no side bars.

Thanks, that is close enough for me then. I will just test a few heights and go with what feels and looks goid.

I have one of McMark's GT bars, complete set up.... haven't gotten around to installing it.

You are free to take measurements off it if you want to take a little drive up to Santa Rosa.

Mocking up the bar in my car:

Careful with those diagonal door bars, I had those in mine , it was uncomfortable
getting in and out especially with the top on, I ended up changing them to this
with a kit I got from jegs , I cut pieces from both ends to get the curve I wanted
then used the extras as you can see for extra bracing , Bill D.
mine is just for street , idea was to add a little more strength to the chassis ?

BuddyV - Thanks for the offer!

Mike - Let me know if I can help. I'd be happy to run up to grab the measurements...

Thanks, that has to offer some strengthening over no tubes at all. Might have to do some testing when I get to that part of my build.

Check out Eric Shea's roll bar too, it looks proper.

In my never ending changing of the mind, I like Bills solution. Car is not going to be a GT clone so who cares how accurate it is. (IMG:style_emoticons/default/smile.gif)

[Alphaogre]

I put a kink in mine for ease of getting in and out. Just an idea... I would say, if you are not going to be doing concourse shows where accuracy is judged, make sure to factor usability and reality into the mix (IMG:style_emoticons/default/biggrin.gif)

[Cracker]

MIke - Much like Chris is ending up with in the RaceRod...a ladder type low slung bar tied into the rocker in at least three places works wonders. Mine wasn't PERFECT like his but did the job - amazing improvement in chassis stiffness and how that translates to instantaneously putting power to the ground.

Is anyone producing these bars anymore, either bolt-in or as a kit?

[ValcoOscar]

Me too...

I would also be interested in a bolt in kit like the one WLD419 posted.

Kit is fine, probably better for shipping. I can weld it. I just don't want to mess with dimensions. I do enough of that.

(IMG:style_emoticons/default/idea.gif) can make some??? tygaboy (Chris) (IMG:style_emoticons/default/poke.gif)

[Larmo63]

Oscar, McMark is your guy on these.......

He made the one in the picture.

I would welcome the extra chassis stiffening these would afford......

Go with McMark, or may be hit up Chris Foley.
They have actual businesses for this sort of thing so I say let's support them. Plus, I'm mildly allergic to deadlines! (IMG:style_emoticons/default/biggrin.gif)

The bar I gave to Mueller was originally going in my car and when I went a different way, I was happy see it go to a good home.

Now, all that said, if someone was to come to the June 2 fab workshop and wanted some help bending up the bars, well... I'd be happy to help!

Seriously, I'm a big fan of communities where everyone helps where they can and I much prefer making stuff and giving it away or helping folks "do it themselves".

My current car came with a cage by Racer Chris/Tangerine Racing...like most anything, it was modified and enhanced to better serve my intended use and fitment.
