i have this bad ass clunking noise from the rear of my car when ever i go slow. i  think that it ts the struts?  anyhow i have purchased kyb gr-2 with dropzonwe springs and coil overs. now when i install them is there any other parts that i should get.  thanks
 
I am having the same problems and someone one here suggested that it might be the rear shock mount???  I havn't been able to check mine yet.
