This is a common problem on the ZX. My '79 sagged the entire time I had it.. It was almost part of it's character - dipping on acceleration.. But, as for the fix.. I installed Eibach progressive rate springs and Tokico struts all the way around ..(replaced all bushings w/ poly, new tie rod ends, etc..).. and the '83 is solid as a rock! A good new set of struts/springs will cure what ail's ya!

Later!

For more advise,
beware of some racing springs because they too will lower your ride in the rear causing serios scrapping..

Jim,

When you say sagging do you mean all the time? If the car was parked, would the rear end sit lower than the front end. If that is the case then yes, you probably should replace the springs. I would replace them with stock unless you are going to replace all four. Having two high performance springs in the rear and two stock springs in the front is going to make for some unusual and undesirable handling characteristics.

If it is just dipping when you accelerate you might want to first go with a new set of shocks. I have an 83T and it dipped a lot when I would start out or under hard acceleration. I installed a set of gas charged KYB shocks and that ended it ever since. I could not get the rear end to squat under normal driving conditions. Hope this helps. Good luck. John
