I'd like to here feedback on these parts and how well they fixed the job? There website said something about slight adjustment. I want to make sure this product is going to be enough. Also stated the factory arm needed some modifycation. What do you have to do here?

 

the spc/eibach kit is a much better option, and using toe bolts is the only correct method for adjusting toe in the rear. The "toe" arms they sell don't adjust toe, they adjust caster, and any toe change is due to misalignment of the suspension
