anything you need for a z car can be found with Victoria British, (www.victoriabritish.com) or motorsport auto (www.zcarparts.com). they have all kinds of performance suspension, KYB shocks, Tokico, Eibach, and Suspension Techniques, that fit right into a z car.

 

If your going to lower you car 2 inches I would almost say you shouold go coil overs. You can get a lighter rate spring to compensate for the stiffness or harsh ride.

Cause about the only way to do it other whise would be to cut the springs..
