I've found what look to be a good deal on some slightly used Eibach Pro Kit springs that will fit a 2004 grand prix. Anybody have any input on the performance of these? If I was to get them I would surely have them on stock rims and tires. I'm told they lower the car 1.0" - 1.5". I honestly don't want the car lowered but am dieing for better handling, which I assume these will help a lot? Are there some kind of spacer plates or something to use with these to control exactly how much they lower the car?
