Cobra roll bar safety

[elmariachi]

The Hurricane is very well done. The rear leg slides down over a 6" long stub that is welded up from the frame in the trunk deck. Then the hoop legs are slid over two frame-welded 6" tall stubs mounted behind the driver's seat. Then the top of the rear leg is slid back up into its spot in the hoop and "wedged" into place and bolted. There are also bolts that hold the front hoop legs onto their mounts but they are really not needed because once the rear leg is wedged into place and bolted, the assembly is tri-pod wedged and cannot move up or down. I also have mounts for an identical passenger rollbar so I can someday be like Patrick. Well, sorta.....

I would not ride in much less own one of these cars without a frame-mounted rollbar.




EDIT>>>And I saw that rolled SPF in NE Houston from last year that was at Vintage Upgrades, in person. The twin rollbars and the way in which they were mounted made ALL the difference in the outcome of that rollover.

Does anyone have an opinon on whether dual roll bars are structurally superior, or inferior, to one full-width roll bar?

If all the mounts are equal in strength, my bet would be the duals would be stronger. 6 mounting points vs. 4.

Deformation is nearly equal from a 45 degree impact with the slight advantage going to the full width bar.

Add a bar from a leg attachment point to the opposite, upper corner (per SCCA requirment) and the full width bar improves dramatically.

Now that is a damn good answer.

I agree with the above assessment of the Hurricane rollbar. I have no doubt in my mind that not only would it support the car in case of a rollover, you could easily lift the whole car by the rollbar.

And as all of us Hurricane owners know, this is but of the MANY subtle but excellent features of our cars that have gone unnoticed because of the limited visibility of the brand in the market. But I think that's all about to change.
