Well i lowered my car last week with eibach sportlines and tokico illuminas and now i have rear rattle issues that is pissing me off and the cause still not figured out. Everything is tight, and bushings that needed changing were changed. Also, the drop is not even all around, the right side is a lil less than 1 inch higher then the left side. WHY??? what can I do??? all this was installed by a prof shop. Any ideas or help would be great.
