Exclamation excessive feathering on drivers side rear tire

hey guys, i was wondering if anyone could help me out.

so i have JIC FLT-A2 coilovers installed on my G. i have the eibach/spc rear camber kit also installed. my problem is that im getting excessive inside feathering on my rear driver side tire. when i bring in my car to get an alignment (which since installing the coilovers a little over a year ago i've had to do about 4 times) the driver side is always at like -3 to -4 degrees of camber. i dont know what keeps happening for only one wheel to have that much negative camber, especially since i have the rear camber kit installed.

i was just wondering if anyone had any insight as to what the problem could be. could it possibly be due to some sort of malfunction with my coilovers? thanks in advance.

most likely the eccentric bolt and or camber arm is slipping causing the change. What are you having them set the camber to initially?

i just tell them to set the camber to OEM specs. the printouts i still have from the alignments have the camber listed at -1.4, and -1.3.

how would the camber arm be slipping? like slipping due to a defective piece? or maybe the people at the place im getting the alignments at just dont know what theyre doing? but if that were the case, then the passenger side would be experiencing the same problem right?

If they don't tighten down the lock nuts on the end of the arm it can slip, or the exxentric bolt could not be properly torqued and is slipping.

so the only thing to do then would be to just keep getting alignments and hope that its done right?

i guess it doesnt help that i am in a little a$$ town for school where the people who work at the shops dont even know what kind of car i have. i guess i'll just wait another week or so and get it done at a more reputable shop in LA. thanks for the help redlude.

Tires are designed to wear properly ONLY with a maximum of -0.5 degrees of negative camber while rolling.........don't confuse sitting still alignment with rolling parameters at speed.

OEM measure at speed parameters and create a static alignment specification that usually works when tires and suspension are new.
