Ok I have a 2003 ZX3 and have just installed Tein STech springs about 3 months ago. Lately, everytime I drive my car, especially at lower speeds and when I turn the steering wheel, I hear like a rattling noise. i have no clue what it is, I checked under the hood to see if maybe the strut tower nuts are loose but they are tight and I have no loose items under the hood. The only thing I can think of is that I blew a strut ( i am still on stock shock/struts ) or that something else isn't bolted up right. The sound seemsto be coming from the drivers side wheel well. I heard that some noise is to be expected with lowering springs, but I was just wondering if some of ya'll with lowered Foci have had this problem. I am planning on getting the Eibach struts/shocks combo soon, but if they will resolve the noise I'll order them next week. Any solutions anyone??
