Camber arm eccentric bolt issue

Camber arm eccentric bolt issue
Recently, I installed BC coilovers and Ichiba rear camber arms and had an alignment done. Afterward everything felt great but the more I drove the handling and ride would get worse and I noticed the wheel on the rear passenger side appeared to be sitting farther back in the wheel well. So, I took the car back to have the alignment checked again and they found the camber and toe on the passenger side rear had moved from where it was set previously. The alignment tech told me the nut for the eccentric bolt will not tighten all the way and thinks the bolt may be partially stripped and this is causing my alignment to change as I drive. Clearly a new eccentric bolt is needed but in starting to research I read that the eccentric bolts *can* slip with hard driving. Has anyone experienced this?
This car is my daily driver but I do some spirited driving with it and next month I will be taking a long road trip, auto crossing it and cruising some mountain roads and want to make sure I don't have any more issues. Will a new eccentric bolt be sufficient or is a lockout kit necessary?

Use lockout bolts and remove the eccentric since camber adjustment is done on the arm itself. Buy spc eccentric toe bolts for more adjustment, although by design, eccentric bolts can slip. if you have true style and not oem style coilovers in the rear then toe arms and lockouts would be a better choice also.

So I could use them only on the camber side (the part farthest under the car) since this is where the problem is occurring and still retain ability to adjust the toe?
Any idea how hard of driving it takes to make SPC eccentric bolts slip or how common of a problem this is? In the research I did prior to installing the coils and camber arms I honestly never knew this could be a problem until now.

It wouldn't be a bad idea. If you don't have time, make some marks so you can tell if one of your bolts shifts at the track events. It will take serious autocross driving or an impact to get one to shift if it is torqued properly.

Sorry to bump an old thread but I am still needing to find some kind of solution. The car won't hold an alignment and it is causing feathering of the front tires on the inside edge. I had it aligned 5 times last year and the alignment guy says the rear toe is out every time I bring it back in which then causes the front to be off. I was reading about traction arms but found info on the Z forums saying they are useless and they kept moving with the suspension travel.

I have been taking it to Nissan so the guy doing the work does alignments at the dealership all day long. The printout always shows things are back in spec when he is done so maybe he isn't torquing them properly. It doesn't take long until it "feels" back out of spec even with normal driving and the fact that the tires are having a wear problem confirms it.

We usually crank those things down with a three footer and some muscle. Have you seen him do it before? I'm no big guy... Unless he is a serious wimp there is probably something else going on here. I would consider marking the outline of the eccentric cams to see if it is the bolts that are moving or something else. They warranty those alignments, no?
