Take into account that the sport kit lower the car 2+ inches. If you have 17 inch wheels your tires might rub, depending on the size and the offset of your wheels (Some of the guys that have the sport kit might be able to shed some light on this). I would recommend changing your strut mounts, and strut bearings up front, the spring isolators, and perches on the back. Also after you let your new suspension settle you will have to get the vehicle aligned, otherwise, as with any suspension modifications, you will wear the inside of your tires rather quickly. One more thing that I would recommend is changing the bushings and rear sway bar end links to polyurethane ones. Hope this helps you.quick question, thinking about putting an Eibach Sport System Kit on my '02 ZX5 and need to know if this is a good fit and what else I need to purchase or consider before install??
