yes, I also have this problenm on right rear only. (07 GP base) 123K MILES, new strut assemblIES today, also have camber adjusting top bolts, but that is not enough for the right side rear. . measured after install of new struts and still off. Am going to remove top bolt and slot strut mount about 1/8th inch, I think that should suffice and get camber same as other side...on a side note, I only get 22k miles out of that right rear tire and inner couple inches of tire was smooth compared to rest of tread that still looked good. other side is almost wearing pefectyly even.
