Ever since I installed the Eibach pro kit lowering springs I have had a little rattle oming from the rear going over pot holes or minor street anomalies. At first I thought it was the stock shocks going bad. I changed them to tokico illuminas and nothing. I double checked the install and all looks well. Cant seem to figure out exactly whats making the rattle but for sure it started after the spring install. Anyone having similar problems?
