If the Z will be a second car soon, I HIGHLY recommend going with everything SPL. My Z is my daily and I will eventually have just about everything in the SPL catalog on my Z.
Spacers don't make the problem worse really from what I have noticed on my car. The stock bushings causing dynamic alignment changes will do the most to cause movement under braking.
Multiple alignments aren't a big deal if you have a trustworthy Firestone shop around you for a lifetime alignment.

I've been suspecting the FLCA bushings. I imagine visual inspection won't tel you much unless they're really gone. What are the impact bushings - never heard of that before? On the FCLA's I've heard great things about delrin but can't find any suppliers. Are they only available as a custom machined part? And what's the material used on SPL's stuff?
My spacers made a small difference when I put them on but seemed very minor.
Check on the lifetime alignment. Very good investment.
