a little over a month ago i had some eibach sportline springs installed on my car which slammed my car to the ground rode like crap and made driving very difficult plus my camber was way off, so now i have stech's on and im starting to notice whenever i go over a bump on the interstate the rear of the car seem to do a wave motion not up and down but like a side to side deal ,my question is what do i need to do to fix this problem because it is really starting to get on my nerves !!!!!!!! oh yea my camber is still off

 

do you have G or Z s-techs?

 

Attachment 81447
these are for a g35

 

You may have blown your shocks or something may have come loose.

 

Did you get a camber or toe kit? How far off is your alignment? It could simply be the toe in the rear.

 

could it be just the difference between progressive and the other type of spring? I forgot what it was called :/

 

Sounds like your toe is way off.

 

Did u buy new shocks or re-use your stock ones??

 

I drove my S.Techs without alignment for a few weeks and didn't notice anything like that. I did put on new shocks when I had the springs added, though.

If you put them on yourself, maybe jack it up and check everything out again. If you had someone put them on for you, maybe go back and have them look at it again. Maybe the shock bolts fell out or something.

 

Linear?

 

....+1

 

so do i buy some new toe arms??

 

you dont need toe arms just go get an alignment
plus there are no such things as toe arms on the g35. some call them toe arms but they are actually traction arms, and they dont adjust toe, they just move the wheel forward and backward in the wheel well.
you can get the spc toe bolts if you feel it necessary

 

Toe all day... it gives you this uneasy feeling like the rear of the car wants to go off to the side or in a different direction than the front.

Alignment necessary

SPC toe bolts might also be needed.

Good luck
