I have a extra set of BRAND NEW never used Eibach Pro Kit rear spings for the Millenia that are for sale, best offer will take them. I have these springs on my car and they lowered the car about 1.5 inches and now the car does not lean at all. The way I came about these extra springs was that I originally installed the spring wrong (back on the front and viceversa) called the company that shipped them to me and told them they sent me the wrong back springs. well then sent me some springs and they were the same as the ones I got, then I realized my mistake when i called Eibach, they told me what numbers went on the front. email me at [email protected] to if your interested.
