I measured all my rear control arms to see if they are off center and they are not. My rear diff/axle is centered in the frame. It's the body that is not mounted square on the frame. I ground away more of the inner fender lip but not enough. I'm swapping coilovers from side to side to see if one coilover spring is soft but it appears they are not. Maybe just go to 245 width tires and issue goes away. (Band-aid fix)
I decide to put a UMI Performance upper reinforcement brace behind the upper coilover mounting points. I also plan to install some lower reinforcement brackets they have that mount bottom of coilovers to inside of lower control arms. Makes the strut more vertical instead of the sharp angle. Unfortunately the lower brackets are on long 2-3 month backorder.
