I have heard a lot of good things about Eibach. Other people have told me to get STEEDA. I am going to lower mine about 1.5 too. I have always thought that they sat entirely too high.
Why pay for a kit. Take a tocrch and heat the springs up and jump up and down on the roof and the trunk ! ! Then you can even have the camber of an indy car. Tire wear might be excessive..
