tubular A arms

Does anyone know, if you go to a tubular A arm, do you have to use a coil over kit?

I need to fix the shimmy in my stearing wheel I have at speed from the crappy bushings, so I figure if I'm getting new A arms and bushings I might as well drop some weight. But if I can't use tubular arms, I'm going with the Ford racing units.

Ok, thanks. I guess those are out. Coil overs aren't in my budget right now, saving up for h/c/i.
