You may also have too much spring frt & rear. Stock fronts were only 235, rears were 355. Hanging stiff springs on a car for competition only works if you run on manicured table-top tracks like Indy or Daytona. For real-world driving and parking-lot GPs (e.g- autocross), the softest springs that keep the car from bottoming, with bigger anti-swaybars, works best. Also, adjusting coil-over shocks is a whole weekend of work using a set of Longacre or other scales and some way of measuring ride height accurately, to do it right. Was this done?
