The lowering bolts should only allow adjustment (lowering) about 1". As stated above you will have to drive the car for a while and allow settling time. Be patient it does settle in nicely. Lowering will create severe negative camber that WILL wear the inside of your tires very quickly. Not to mention traction and handling difficulties. You must get a proper re-alignment to correct the camber. The stock camber adjustment cams will only allow enough correction to accomodate approx. 1" of lowering. You will need to replace the rear camber strut rods(?) with an adjustable aftermarket item if you want it lower. Good luck.
