Removal of the stock upper and lower insulators will lower the car an additional amount but will also increase harshness, road noise, and squeaks. If ride height is still too high after several hundred miles of spring "break-in", removing 1/2 coil from the spring will lower car approximately 1/2 - 3/4". Remove this material from the *bottom* of the *front* spring and the *top* of the *rear* spring if desired.
