I have a Metal Tech cage in my 40. My swampers are great until I hit 50 to 65 mph where there is enough shimmy to cause the cage to oscillate side to side. The tires are balanced with tire beads and are not going to get any better. The side to side movement at the top of the A pillar is not quite a 1/4" and a little bit of hand pressure will lessen it. I am designing a new bikini top that I would like to roll around the outer edges of the cage. This would create an issue when the cage is moving side to side. I fear it will badly wear on the top fabric.
I am searching for options to stiffen the cage enough to to eliminate the shimmy without causing issues with frame/body flex when wheeling. My first though was to attach the dash cross bar to the dash, but that could lead to too much stress when the frame flexes. Instead I am wondering if a little triangulation might add just enough stiffness. I just don't have any experience in this area to know one way or the other. My thought is to add a tube on each side connecting the A pillar to the dash cross bar as seen in the picture. Do you guys think this would be enough? Worth it, not worth it? I could add it above the cross bar although that would impinge on vision a bit. I might be able to do it at the top bar, but again that impinges on the forward vision. I would do it if it would make a bigger difference though.
Thoughts?
Thanks
