Cheers Tony, Z has had a huge number of alignments by all the best guys in the business in my city in NZ. Most recently 3 full alignments in one week, having only covered 100kms approximately. Each time moves and changes. This is more than just an alignment issue. Thank you anyway.

 

I know this is over a year and half old, but trust me its the piece of sh*t kinetix arms. I changed mine to SPC arms and problem was solved. The bushing that kinetix uses is a POS.

try driving in the rain with that wiggle and i guarantee you will lose control.

 

Running full stiff on the rear sways will also cause this a bit. Full stiff on any Hotchkis bar(front or rear) is way to stiff for street tires and will cause some odd handling.

 

I don't think I posted this here yet:

The problem was the camber arms. After checking everything else, I finally removed them and examined how it worked with the car. I noticed that the steel ring in the center of the urethane stuck out further then the rest of the arm. My theory is that when the car would hit a bump, that metal center would dance around freely. No washers came with the camber arms, just the toe arms.

We resulted in grinding down the metal to sit flush with the urethane. Been happier with the care since.

 

^ what camber arms are you using? I hope i don't have to modify my SPCs.

crap... I am experiencing this problem after installing my SPC rear camber arms and coilovers and dropped them to 1 finger gap. Bet they're way off spec right now. Makes me feel a bit scared to drive it when the rear "wiggles" on bumps. Think the toe setting is way off actually, it's definitely toe in right now, gonna try to adjust it tomorrow to see if I can get it a bit better b4 I take it to a shop to align it.

 

Same problem here. I have Ichiba rear camber arms. Makes me not wanna drive my car anymore, I had like 3 alignments already @ $75 each. I noticed when I lowered my car with Sportlines with the oem rear camber, the *** didn't use to wiggle. Now with Ichibas it wiggles crazy =X i don't know anymore lol

 

Just an idea because I had the same situation. Retorque your camber arms. I noticed when I had the problem and double check my work. One bolt was loose and I could turn it with me hand. If I didn't check again I don't know what would have happen. Just my suggestion.
