Default Questions about suspension geometry

i personally don't know ANYTHING about geometries of anything in cars.
If i get a tein S-tech then i'll be needing rear camber and toe adjustment.
Will the replacing of traction/toe arm change the geometry of the suspension?
I think i heard from RSX forum..not sure.
I know that toe bolts are much cheaper but i heard that they slip under hard driving. So i'm thinking of Kinetix rear camber and traction arm combo for $250..

help me out with knowledge

50 percent of the suspension threads here are about making the car look cool.
The other 50 percent are about fixing what you just screwed up.
You will figure it out.

Ok first of all,

With the S-Techs, you should not have to change ANY suspension components whatsoever...just wait a week or 2 after spring install and go get an alignment.

With the S-Techs, the drop is F .7 R .6. Both are below staying above Nissan recommended .8 f/r, because at that point you will ultimately need rear kit first, then front kit if go even lower.

You should not need to change ANYTHING bud. I have S-Techs and the shop is very easily able to get my rear camber and toe into spec using stock suspension components.

SO this, of course, leads me to ask you, why would you want to change the rear arms at all?

Then you need an alignment, bro.

Sounds like your mistaking your wear for camber, when in fact it is most likely toe wear.

I just read your other thread...................................................... ............................................................ ............................................................ ........................................







It would have helped for me to know you have a G35 and not a Z.....

Well, whether it's now or later, we need rear camber/toe right? maybe some cars don't lol. You are lucky if you dun have to get the kit.

yes, changing the rear traction rod length will change the rear suspension geometry.

the only way to know for sure how much is to plot the curves using a bumpsteer gauge.

if you are worried about the toe bolts slipping, you can always upgrade to splparts.com midlinks with eccentric lockouts.

fwiw you might not even need toe bolts.

Will eccentric lockouts give me toe adjustability with elongated holes? or do i need both SPC toe bolts and SPL lock outs?
