well I have gone freakin insane...my car makes this rattleing vibration in the rear and I have gone through preety much everything I can think of...its only on rough roads and its facking annoying...its sounds like the struts but I have replaced all the mounts and changed nearly every bushing since I put the rear disc on...it even does it with the tokicos...I have tightend my strut bar and made sure the strut mount towers are secure also...any ideas?
