sirelesar,

Thanks for the response, I haven't driven my car enough to evaluate steering, but I have noticed yaw a couple of times, and wasn't smart enough to know it was caused by bumpsteer.

I have the B&b tube arms which are shortened 5/8 inch and am also having tire-to-fiberglass contact, caused partly by my backspacing decision. My original backspacing resulted in a 3 piece wheel where the inner piece actually extended about 1/2 inch beyond the face of the outer rim. When I looked at other Cobra's, I was surprised to see that this is not uncommon, but I just couldn't live with the appearance, so I had the backspacing decreased 1 inch, and now I have contact problems.
I don't have a solution yet, but I will either limit upward travel with bumpers and/or fabricate custom hubs which move the wheels inboard. Then I will deal with bumpsteer. Seems like the custom rack is an attractive solution, I'm wondering if I can also get a faster ratio. However, I have seen one B&B with a flaming river rack, and if memory serves me correctly, the mounting required considerable change to the setup.
