i would just watch you tires and rotate them every oil change. my camber is out about the same as yours and my tires are doin just fine. I do notice they are wearing a little more on the inside than the outside, but ive had them on there for 6 months and They should last a while. If you do get a camber kit your gonna need to Ingalls extreme camber kit that corrects from +1.25 degrees to +3 degrees.
