Dual roll bar question

[tcollins]

I just ordered my 33 hot rod kit and was surprised that FF does not actually offer and option for the dual roll bar. I've seen several images of this and wondered if anyone could help suggest the best approach to make this happen?

I have two of the original FFR roll bars that FFR supplied. They are untouched raw steel, as supplied. You would have to weld stubs to your chassis to fit the bars. I would be willing to sell these now very rare, pre-production pieces. Where do you live? (you should have that in your profile) Shipping might cost a few $$ though.

Now thats an offer! Fed ex ground it usually pretty good for shipping.....nothing is cheaper than greyhound bus lines for shipping......Steven

Oxford, Michigan...I thought I did include that in my profile...just joined the forum perhaps I screwed it up? How much to do want? and how far are you from Philadelphia? MY brother lives there and is coming this way soon.

Do you know why FFR stopped offering these?

[Olli]

$100. + shipping. I am roughly 2 hours from Philly. I don't know why FFR discontinued the roll bars.

For some reason your location didn't show on your first post. Clearly, it does now.

The hard top did not fit with the dual roll bar design.

Can they be made to fit at all??? I prefer the look of the Dual bars over the single hoop....

thnx

I have a single roll bar available on my web site that you might like. Heavier than the factory offer. You can see how it looks on my build site mounted on the car. It actually sits about 3" lower in its final resting place than pictured.

Sure they can. It's all just a sacrifice over actual functionality vs looks. You could mount them perpendicular (90degrees) to the chassis and take off a couple inches and you should be good to fit under the top. However, once you start lowering them, they lose their ability to save your neck in roll over. This is similar to the Miatas in which their roll bars are actually called "Style Bars" to limit any liability the manufacturer has. While they look great, most Miata owners who race road courses move to a real roll bar which looks more like the FFR square one.

What do you mean perpendicular??? Vertically speaking??? Rather then leaning back??

thnx

Yup! I'll take a look today when I take my top off and see how short you would need to make them in order to fit.

I had a set of bars made at a local race car fab shop. They fit behind the Kirkey seats and just hit the soft top. They are vertical to match the head rest angle. We welded in inner tubes for extra strength.96279628

Would you mind sharing the specs on these? Tube diameter, height, width and tabs? I love your design and am trying to get it together for my own. Thanks.

[Jay Mann]

Thanks for the compliment.

The tubes are 1.75 o.d. x .120. which is a common tube for circle track roll cages. The height is approximately 24 ". The height was limited by the clearance under the rag top and the back of the Kirkey seats. I did not use tabs, they are welded in solid to the frame and to the extra cross member I put in. The width was determined by the die that the shop had, I think it is 6 1/2" radius, approximatey. To give the hoops more strength, we inserted 12" lengths of 1.5" x .120 tube inside the hoops and plug welded them. This significantly increases the strength in the area of the cross bar. I have no illusions about the safety of these bars, if the car tips, they will help, but if it tumbles, all bets are off. They are many times stronger than the single 1.5" bar that was supplied with the kit. BTW, the hoops and insert tube cost us $200 at the race shop, we did the fitting and welding ourselves.

Thanks for the info. I love you guys in this forum, everyone is so eager to share. Ordered my kit this morning, and have been very busy spending money today. Mine will be for asthetics with a "little" safety in mind. I am with you about rolling, all bets are off...hopefully none of us will have to find that out! Your Coyote is awesome. Hope mine comes out half that nice! Thanks again.
