Before you do that, think about this.

There are some bushings on there tha tyou don't even need to purchase.

first off, to autocross you'll probably want
adjustable caster front
adjustable camber front and rear
adjustable toe front and rear

from the factory you get

adjustable camber rear
adjustable toe front

splparts www.splparts.com can get you actual control arms that replace the bushings entirely with spherical bearing joints. i.e. piro ball.
also, get solid tc rods, they are cheap, like 150 or so. worth every penny, and adjustable to get you more caster. more caster in a 13 / 14 is a Godsend.
adjustable rear upper control arms and rear toe arms are great to get also

subframe spacers from spl parts also, cheaper than bushings and TONS easier to install also.

the only poly bushings i am getting is from energy suspension actually, and they are front lower contorl arm bushings for a z32, and steering rack bushings for a Z32. both of those I know how to modify to make work in a S chassis.

The rest of my stuff is all going to be piro balled. I already have solid front tc rods, rear camber arms, subframe spacers. my toe rods are OVERDUE and have been paid for for sometime now, but unfortunatly they're on backorder. I might just have to upgrade to some JIC's, or cancel my order and get some SPL parts ones. The toe links are next to go. then I wont have many bushings to get at all.

Maybe some rear lower contorl arm bushings or something.

for the front, i'll do the S14 lower control arms entirely, but with an S13 ball joint. why? The spindles are slightly different, it wouldn't work any other way. And while the control arm's out.. you guessed it, a black poly bushing.
