don't expect a smooth riding car after you install it. ebay coilovers are usually cheaply made. i think you shoul've asked around the forums before buying something like that.
Either they were a set of used dropzone coilovers which i've heard mixed reviews about or they were some cheap no name coilovers. I was gonna bid on some ground controls but the seller never replied to my question as to what kind of struts they were for.
