I installed new springs (eibachs) and did about 2 inch drop in theback and 1.5 inch in the front. I left the front higher since my sister also drives the car and she scratches....... even on stock ride height.... but after i installed the springs my car became very bumpy and stiff (feels like im going off roading somtimes...). Im sure this is the normal affect of having a dropped car, i also have a strut tower brace and super subframe connectors from kenny brown. Do you guys have any advice on how to make my car a smooother ride..
