so after lots of reading, I went ahead and ordered a new suspension for my '03 coupe. parts list:

350Z RSR Springs
350Z Tokico D-Spec Shocks
Stillen Front & Rear Sways
Prothane Bushings for Sways
Kinetix Front A-Arm , Rear Camber/Traction Arm Package

someone suggested that i get new cotter pins for the front upper A arms to replace the ones that get pulled out when uninstalling the OE suspension and to reuse the OE rubber upper mounts. is this correct? anything else that might need to be replaced? my '03 w/ sports package has 60k miles, so I'm not sure if any other bushings, etc are prone to failure around that time. if anyone has some suggestions or part numbers, it would be much appreciated. thanks!

 

yeh, since you're replacing the a-arms anyway you'll need to get new cotter pins. You might be able to salvage the factory one, but it'll probably break off when you
unbend it so just get some new ones. $3 for like 30 of them.

If you were going to keep your factory arms you can remove the arms from the
chassis and not have to remove the cotter pin and the nut holding the knuckle.

 

do you know where i can get these? or what size? picture maybe? thanks!

 

any auto parts store has them.

here's a generic pict. not sure wat the size was off hand.
just look into your front wheel well and you'll see it.

 

cool, thanks. most of this stuff *should* be here by the end of the week, so hopefully i can get it installed soon. might have some more questions though, lol.
