Hey guys, so recently I replaced my nismo s-tune springs with tanabe GF210's on nismo shocks/struts (8k on them) along with the install of camber arms F/R +toe w/proper alignment. One problem i'm having now is that my rear end tends to shift from one side to another only on large bumps but drives absolutely normal other than that. One thing I have to include is that when my buddy was doing the spring install, he disassembled my rear shocks on accident and made me drive with an incorrectly assembled strut for 3 days which made a horrible clunking sound going over bumps. Do you guys think that blew out the strut? I also had a mechanic reassemble my strut assembly and he told me that the struts seemed good. I also checked my tire pressure and had a proper alignment. What do you guys think the cause can be? Help will be greatly appreciated.

 

Anybody? My rear end dances over bumps and jerks to one side. help!

 

What year is it?

 

05 with 58k. I've done some research and a possibility can be a poor alignment with my rear toe off? My rear toe is at 1.2mm looking at the specs the shop gave me.

 

Mine kind of did the same thing when I installed my toe arms, untill I adjusted them properly. I also have RAS so it felt like my rear end was gonna slip out when I was on the highway.

 

Should I bring it back and have them align it again? &What do you mean by adjusting them properly?

 

My toe was way off and you could clearly see it. I adjusted it (eyeballed it) and it stopped. Do you have toe bolts?

 

Yeah the shop installed my spc rear camber arms and toe kit on the same day of alignment.

 

Then they should have been able to get your toe within specs, hmm, drive it as least as possible sense it's gonna start wearing your tires out and it doesn't seem very safe and get it realigned.

 

Did they know that they were support to bore out the hole where the toe bolt goes? I had to tell the alignment shop to do that sence they don't read instructions.

 

I did not as the shop had a reputation working on G's in the bay area and the tech also told me he had a G35 in the past. From looking at the specs they gave me, the rear toe on the left is 1.2mm and the right is 0.9mm.

 

Another thing is that i'm running -4 camber in the back currently with my temporary oem rays with 255/40/19 tires if that is a problem? Running camber + wider tires = problems?

 

I could see all those things contributing to the problem. There is only a certain amount of toe the bolts will allow when your adding lots of neg camber. Then you will need to invest in toe arms. Which means true type coilovers.

 

I already have the spc rear camber arms installed. It seems like my alignment is within spec.. maybe have it aligned with my new wheels/stretch tires and have them bring the toe to zero?

 

They should have brought it to zero from the getgo
