I just had a local dealer here in DFW install the Eibach kit along with some SPC upper control arms. I had tire rub before, but with my caster now sitting at about 4.7 the rub is gone (running 275/65 right now). Overall, I am thrilled with the kit and highly recommend it. It just soaks up all of the road imperfections like it's nothing now. Very composed and it handles on rails in the corners. Here are some before and after pics. I had a Revtek front spacer kit before the Eibach kit. I should have just done the Eibach kit to begin with!
