Need a shopping list of suspension parts

OptionZero

you want to grab all the stuff and install it once so you only align it once

The Z34 has zero front adjustment from the factory, just a fact of life.

The rear has limited adjustability, unlikely to be enough to compensate for any sort of significant drop.

You said you want the alignment to get "right." What's that mean?

Most people think they just want to get to factory spec, but . . . factory spec sucks.

If you want to improve your handling at all, you want a couple degrees of negative camber in front and rear, increased camber, and then to save your tires, zero out your toe.


Anyways, parts, at minimum, to do it right, go here:
https://www.splparts.com/09-370z-z34/

SPL Front upper control arm (FUCA)
SPL rear camber arm
SPL rear traction arm
SPL lockout kit

This is also where your coilover choice comes with an inflection point, and why I recommend against the KW V3's:

OEM type divorced coilovers (Spring and damper separate) will use the SPL mid-link, which mimics the factory bucket design but with added strength and adjustability

That part, however, is designed for a 65mm ID spring

KW's use a digressive (cone-shape) rear spring, which, I THINK, don't fit in the bucket. Someone can correct me if i'm wrong.

The solution would simply be to grab a set of swift springs, which SPL can get you. They'll be better than the SPL springs anyways and fit the SPL bucket, and comes in a variety of rates and heights.

Make sure to grab some thrust washers while you're at it, which will cut out the popping noise from springs binding.
