Why spend more money on coil overs? Just get some new springs that won't drop you as low. Like Eibach 1.5 or Progress "2" which is what I have. I hate to say it but I do not think that is going to fix the problem. If being slammed was issue then the struts may have taken more of a pounding. Toe in toe out causes uneven tire wear more than it would cause the ass end to do the cha cha. Unless the toe is so bad th wheels are astronomically pulling away or pointing into eachother.
