I have just gotten 18 inch saleen wheels 18x9 with 245/45/18 tire and pretty much only rub on freeway bumps. Im not sure my existing struts are going bad but i notice my car does have a bit more bounce than say the 98 buick lesabre my buddy has thats even older than my 2002 grand prix. Would the KYB adjustable struts in the rear atleast help keep the tires from rubbing that plate on the spring strut assembly?
