Other than getting an alignment (I am set at ~-.65 in the front and -1.75 in the rear), I can say having the Nismo springs and struts installed was definitely a worthwhile upgrade without making any additonal suspension changes.
It is a wee bit harsh, but only at first -- once the springs settle is is very stable and comfortable on all except the more uneven roads, where it is stiff but not unnerving.
Start, stop, and cornering are all greatly improved, with much more overall chassis rigidity and responsiveness.
Haven't felt the need to upgrade the sways just yet, but will consider this next... as is, can really throw it into corners -- feels great, much more surefooted and precise than standard OEM suspension
