Car is a 97ss all stock suspension wise... I see on slp's website a package that is bilstiens with eibach springs for about $650 and its supposed to lower the car a half inch... now is this the suspension that came on ss and firehawks with the suspension package? Also I had kyb agx and the eibach pro kit on my first 3.4 camaro and the ride was very rough and the rear axle used to hit the bump stops all the time so idk if I want eibachs again... anyones opinions?
