No, those will not help the steering at all. What they will do is put extra stress on the springs, causing premature breakage. Just judging from how you describe the handling, the alignment is off, namely, it sounds like you have negative caster. Have them set the caster to about 3.5-4.5 degrees. Camber should be about .5-.75 degrees positive, with about 1/16"-1/8" toe in.
